Our mission

Scale nuclear energy. Power generations.

Our vision

A maritime commons thriving with abundant, economical, modern, and safe nuclear-powered activity — built, serviced, and staffed by re-industrialized American shipyards and people.

Role Summary

As Nuclear Systems Engineer, you work on the system-level design of the reactor systems that power our maritime nuclear plant: core, primary loop, power conversion, shielding, auxiliaries, and instrumentation & controls, from early concept studies through integrated design and handoff to build. You resolve the interfaces between nuclear, thermal-fluids, mechanical, structural, and controls disciplines, and keep the design compatible with the regulatory pathway and the constraints of the host vessel: mass, volume, motion, shock, and the marine environment.

This is a role we're hiring at multiple levels (L1 through L4). The work is shared across levels; scope and accountability scale with experience.

This work suits someone who treats interface conflicts as the real design problem rather than paperwork between disciplines, and who knows which trade-offs need to go up for a decision instead of getting resolved by fiat.

What You'll Do

At all levels, you will:

• Support architecture and integration of primary and secondary reactor systems — core, primary loop, power conversion, shielding, auxiliaries, and I&C — across concept, preliminary, detailed, and final design phases.

• Contribute to concept selection and trade studies, and help allocate requirements to discipline owners.

• Coordinate with nuclear, thermal-hydraulic/fluids, mechanical, structural, and controls engineers to resolve interfaces and close integration gaps.

• Maintain system requirements, interface control documents, margins, and master block diagrams; participate in design reviews and phase gates.

• Partner with safety, licensing, and naval architecture engineers to keep designs compatible with the regulatory pathway and host vessel constraints (mass, volume, motion, shock, marine environment).

At more senior levels (L3-L4), you will additionally:

• Own the integrated design baseline and lead architecture decisions across primary and secondary systems.

• Drive concept selection and trade studies, and allocate requirements down to discipline owners.

• Run design reviews and phase gates, and surface the trade-offs that need executive decisions.

• Track risk and manage technical debt across disciplines at the system level.

What You Bring

Required at all levels

• Bachelor's or advanced degree in Nuclear, Mechanical, or related engineering, or equivalent practical experience.

• Direct experience with a reactor or comparable complex thermal/energy system, from concept through detailed design — not just analysis of a system someone else designed.

• Systems engineering fundamentals: requirements, interfaces, verification & validation, configuration control, margin management.

• Working fluency across nuclear, thermal-fluids, and mechanical domains, enough to challenge each specialty without owning their analyses.

Experience by level

• L1-L2: Early-career engineers with systems engineering exposure through internships, research, or early-career roles on reactor or complex energy systems.

• L3-L4: Have taken a reactor system (naval propulsion, microreactor, SMR, or research reactor) from concept through detailed design, and can own an integrated design baseline across disciplines.

Preferred

• Naval reactors (NR) experience.

• Shipboard or offshore systems exposure.

• Licensing experience with the NRC or a maritime classification society (ABS, LR, etc.).

Role Summary

As Auxiliary and Distribution System Lead, you lead the engineering of the internal fluid networks, electrical distribution, and auxiliary systems for the vessels that carry Ocean Atomics' nuclear electric plant: the cooling loops, switchgear, piping runs, and containment isolation networks that ready the platform side for plant integration. You define how those systems carry power, coolant, and control across the vessel, from initial concept through class and flag-state approval, working with naval architecture, marine engineering, and our nuclear integration team. The interface boundaries you set are where the plant's auxiliary connections integrate cleanly, without a mid-cycle redesign — the connective work that lets our plant scale from the first vessels to a repeatable build.

The ideal candidate treats interface discipline as the thing that makes downstream integration boring in the best way, and would rather resolve a routing conflict on paper now than discover it in the shipyard later.

What You'll Do

• Lead the engineering, routing, and optimization of the platform's internal fluid networks, piping configurations, and auxiliary distribution systems from initial layout through deployment.

• Design the high-capacity cooling loops, electrical switchgear, and containment isolation networks so they're built for plant integration from the start, not retrofitted.

• Model electrical load profiles so auxiliary systems hold stable across both conventional transit and active power-generation modes.

• Establish the mechanical and structural interface boundaries that let conventional ship networks accept reactor auxiliary inputs without a mid-cycle redesign.

• Develop modular, reproducible auxiliary configurations that reduce shipyard fabrication complexity and minimize spatial routing conflicts.

• Generate the piping and instrumentation diagrams (P&IDs), fluid-flow calculations, and technical data packages that clear classification society (ABS, LR, etc.) and flag state (USCG, etc.) reviews, coordinating with our nuclear integration team on reactor-side interfaces.

What You Bring

Required

• Bachelor's or advanced degree in Marine Engineering, Mechanical Engineering, or related discipline, or equivalent practical experience.

• Track record leading system-level auxiliary, fluid-network, or distribution design from concept through deployment. Typically built over 8+ years of focused work in marine auxiliary systems, complex fluid-network design, or mechanical distribution architecture across commercial ships, naval vessels, or heavy offshore platforms. Depth of experience, design cycles, and successful leadership of major distribution projects is valued above years of experience.

• Working command of marine piping and thermal-management engineering, switchgear integration, and fluid-analysis tools, grounded in classification society machinery rules (ABS, LR, etc.) and flag state regulatory processes.

Preferred

• Experience with highly regulated vessel classes or systems requiring nuclear or high-hazard integration.

• Background in modular ship design or repeatable fabrication processes.

• Cross-functional experience partnering with naval architecture, marine engineering, and plant integration teams on integrated designs.

Role Summary

As Electrical Lead, you lead the engineering of the high-voltage (greater than 1000 V) and low-voltage (no more than 1000 V) distribution, power management, and grid-synchronization systems for the vessels that carry Ocean Atomics' nuclear electric plant: the generation busses, switchboards, load centers, and power panels, and protection networks that prepare the platform side for plant integration. You're responsible for how power is generated, distributed, and protected across the vessel and out to onshore utility grids, from initial concept through class and flag-state approval, working closely with marine engineering, naval architecture, and our nuclear integration team. The electrical interfaces you design become the boundary that lets the plant tie in cleanly, and you'll establish the electrical baseline every vessel that carries our plant is engineered against.

The ideal candidate treats electrical safety as non-negotiable while still finding ways to compress the design cycle, and can hold a clean interface boundary without turning it into a bureaucratic one.

What You'll Do

• Lead the engineering of high-voltage and low-voltage AC and DC distribution, power management, and grid-synchronization systems from initial layout through deployment.

• Design the main generation busses, switchboards, load centers, transformers, and protection networks so they're designed for plant integration from the start, not retrofitted.

• Develop modular, reproducible power distribution configurations that reduce shipyard fabrication complexity and downstream assembly risk.

• Design and validate the marine-to-shore electrical equipment and control protocols that transfer power to onshore utility grids safely and stably.

• Perform endurance fuel calculations.

• Run load-flow, short-circuit, voltage drop, harmonic current, dynamic response, stability, black-out recovery, in-rush current, quality of service, and protective relay coordination studies before steel cutting begins.

• Ensure the design adequately addresses common mode voltages and currents; Ensure the electrical distribution system is electromagnetically compatible with itself and other ship systems.

• Ensure the electric plant control system is designed using the ship’s cybersecurity framework.

• Determine equipment design requirements to minimize maintenance and repair costs.

• Conduct supporting analysis to calculate annual operating costs.

• Generate the single-line diagrams, load analyses, and technical data packages that clear classification society (ABS, LR, etc.) and flag state (USCG, etc.) reviews, built to 46 CFR, IEEE Std. 45 series, IEC (where needed), IMO (including SOLAS and MARPOL), and relevant marine electrical codes.

What You Bring

Required

• Bachelor's or advanced degree in Electrical Engineering, Marine Engineering, or related discipline, or equivalent practical experience.

• Track record leading system-level marine electrical design from concept through deployment. Typically built over 8+ years of focused work in marine electrical systems, industrial power systems, high-voltage offshore distribution, or comparable regulated power systems. Depth of experience, design cycles, and successful leadership of major electrical projects is valued above years of experience.

• Working command of high-voltage power generation, switchgear specification, and protective relay coordination.

• Working knowledge of classification society electrical rules (ABS, LR, etc.), flag state regulatory processes (USCG, etc.), and marine electrical codes (IEEE 45, IEC, SOLAS).

Preferred

• Experience with grid-synchronization and marine-to-shore power transmission.

Role Summary

As Marine Propulsion Lead, you lead the engineering of the propulsion machinery, shafting, and thruster architectures for the vessels that carry Ocean Atomics' nuclear electric plant: the prime movers, reduction gears, steering systems, and auxiliary transit networks that prepare the platform side for plant integration. You're responsible for how those vessels move, maneuver, and hold station once the plant is integrated, from initial concept through class and flag-state approval, working closely with naval architecture, marine engineering, and our nuclear integration team. The mechanical interfaces you design become the boundary that lets the plant drop in cleanly. This is the work that brings maritime nuclear into being, and you'll establish the propulsion baseline every vessel that carries our plant is engineered against.

The ideal candidate holds mechanical rigor as a non-negotiable while still finding ways to compress the design cycle, and knows the difference between safety theater and actual safety.

What You'll Do

• Lead the engineering of propulsion machinery, mechanical shafting, and thruster systems from initial layout through deployment.

• Design the integration of prime movers, reduction gears, steering systems, and auxiliary transit networks so they're designed for plant integration from the start, not retrofitted.

• Establish the mechanical interface standards and alignment tolerances that let our nuclear electric plant integrate cleanly into the platform.

• Develop modular, reproducible propulsion configurations that reduce shipyard fabrication complexity and downstream assembly risk.

• Run torsional vibration analyses, shaft alignment modeling, and hydrodynamic boundary assessments before steel cutting begins.

Role Summary

As Habitability Lead, you lead the human factors engineering, environmental control systems, and living-space architecture for the vessels that carry Ocean Atomics' nuclear electric plant. You're responsible for how crews live and work aboard — berthing, ergonomics, and life support — from initial concept through class and flag-state approval, working closely with the Arrangements and Structures leads so crew spaces are designed for plant integration from the start. The habitability baseline you set keeps crews safe and mission-ready across long offshore deployments, and it's part of how Ocean Atomics scales nuclear energy at sea.

The ideal candidate treats crew safety as a first-order design constraint rather than a compliance afterthought, and knows how to defend habitability margins without turning class and flag reviews into box-checking.

What You'll Do

• Lead the spatial design, berthing layouts, and living-space architecture of crew spaces, optimizing ergonomics and endurance for extended offshore deployments.

• Design, specify, and validate the vessel's environmental control systems, including radiological HVAC filtration, internal safety airflow, and emergency life-support systems.

• Work with the Arrangements and Structures leads to protect space and weight margins so crew systems adapt cleanly to the constraints of plant integration.

• Develop modular, reproducible habitability configurations that reduce shipyard fabrication complexity and downstream assembly risk.

• Address human-system interface and life-safety issues early in the design cycle, before they become costly late-stage changes.

• Generate the human factors analyses, drawings, and environmental control schematics that clear classification society (ABS, LR, etc.) habitability notations and statutory flag state (USCG, etc.) reviews, and that support NRC-facing safety documentation.

What You Bring

Required

• Bachelor's or advanced degree in Naval Architecture, Marine Engineering, Mechanical Engineering, Human Factors Engineering, or related discipline, or equivalent practical experience.

• Track record leading habitability, marine environmental control, or human factors design from concept through deployment. Typically built over 8+ years of focused work in marine habitability, shipboard HVAC/environmental control, or human factors engineering for commercial vessels, offshore platforms, or naval assets. Depth of experience, design cycles, and successful leadership of major habitability projects is valued above years of experience.

• Working command of marine life-support systems, radiological filtration design, and human-system interface standards (e.g., ASTM F1166), with a solid grasp of classification society (ABS, LR, etc.) and flag state (USCG, etc.) habitability requirements.

Preferred

• Experience with highly regulated vessel classes or habitability notations.

• Background in modular ship design or repeatable fabrication processes.

Role Summary

As the Naval Architecture Arrangements and Weights Lead, you lead the general arrangements, spatial allocation, and weight control for the vessels that carry Ocean Atomics' nuclear electric plant. While naval architecture defines the outer hull, you're responsible for the internal spatial footprint and mass distribution: the weight engineering matrices, center of gravity tracking, compartmentation, and equipment envelopes, from concept through deployment. The margins you hold are what let our plant integrate into the vessel cleanly without late-stage structural rework, and keep the vessel stable across decades of operation.

The ideal candidate treats weight and margin discipline as the quiet foundation of a safe design rather than box-checking, and can hold a threshold under design pressure without turning a review into a standoff.

What You'll Do

Role Summary

As Hydrodynamics & Stability Lead, you lead the seakeeping, hydrodynamics, and stability engineering for the vessels that carry Ocean Atomics' nuclear electric plant. You're responsible for how those vessels move, hold station, and stay stable in real ocean conditions, from initial concept through class and flag-state approval, working closely with the Principal Naval Architect and our structures, weights, and nuclear integration teams. The plant is a heavy, high-consequence payload that reshapes the stability problem, and your analysis is what demonstrates a vessel can carry it safely across its service life. This is the work that brings maritime nuclear into being, and you'll set the seakeeping and stability basis every vessel that carries our plant is engineered against.

The ideal candidate holds stability margins as sacred while staying energized rather than rattled by a payload no one has designed a vessel around before, and treats class and flag review as problem-solving rather than box-checking.

What You'll Do

• Lead intact and damage stability analysis across operating, transient, and damaged conditions, demonstrating adequate righting energy and survivability against SOLAS, class, and flag criteria for a vessel carrying a heavy reactor payload.

• Run hull-wave interaction modeling, CFD, and model-test campaigns to predict seakeeping and motion behavior in the metocean conditions the vessel will operate and hold station in.

• Establish and protect the KG, weight-growth, and buoyancy-reserve margins that let the hull accept our nuclear electric plant without eroding stability across the service life.

• Design and analyze station-keeping and mooring configurations, and run the dynamic simulations that keep the vessel on station across a decades-long service life.

• Partner with the Principal Naval Architect, structures, and weights teams, and with our nuclear integration team, so the hull's stability envelope is designed to receive the plant from the start, not retrofitted.

• Produce the stability booklets, hydrodynamic reports, and safety-at-sea documentation that clear classification society (ABS, LR, etc.) and flag state (USCG, etc.) reviews.

What You Bring

Required

• Bachelor's or advanced degree in Naval Architecture, Marine Engineering, or a related discipline, or equivalent practical experience.

• Track record leading hydrodynamics, seakeeping, and stability work from concept through class approval. Typically built over 8+ years focused on marine hydrodynamics, stability, or floating-system design in offshore, naval, heavy-lift, or comparable high-consequence contexts. Depth of experience, design cycles, and successful delivery of major stability and seakeeping work is valued above years of experience.

• Working command of intact and damage stability criteria and of class society (ABS, LR, etc.) and flag state (USCG, etc.) review processes.

• Proficiency with the hydrodynamics and stability tool stack (GHS, MOSES, WAMIT, ANSYS AQWA, or equivalent).

Preferred

• Experience with floating production or offshore assets (FPSO, semi-submersibles, spars) where weight, stability, and mooring are unforgiving.

• Background in naval survivability and shock, or in high-consequence cargo vessels (LNG carriers, heavy-lift).

• Experience helping establish the technical or regulatory basis for a first-of-a-kind or novel vessel class, rather than only demonstrating compliance against mature rules.

What You'll Do

• Design and analyze core mechanical components and internals for structural integrity, fatigue, and wear across operating, transient, and accident conditions including those unique to the maritime domain.

• Evaluate flow-induced vibration of fuel assemblies, control elements, and internals, and develop design features to mitigate wear and dynamic effects in marine operational load profiles.

• Assess the effects of ship motions and dynamic/shock loading on core mechanical performance and structural margins.

• Coordinate with thermal-hydraulics, fuels, and structural teams to integrate mechanical design with flow, thermal, and neutronic requirements.

• Document mechanical analyses, design basis, and qualification results, and support design reviews, testing campaigns, and regulatory documentation.

At more senior levels you will additionally:

• Lead system-level decisions on core mechanical architecture and material selection.

• Mentor newer engineers and review their analyses.

• Interface directly with our regulatory team on NRC-facing documentation packages.

• Drive cross-team trade studies across thermal-hydraulics, fuels, and structural domains.

What You Bring

Required

• Bachelor's degree in mechanical or nuclear engineering required

• Experience in mechanical design and structural analysis of reactor core components or internals.

• Proficiency with finite element analysis and structural/vibration tools (e.g., ANSYS, ABAQUS, or equivalent).

• Working knowledge of flow-induced vibration, fatigue, and dynamic/shock loading analysis.

• Strong grounding in solid mechanics, materials behavior, and structural dynamics

Preferred

• Background in naval architecture, marine engineering, or offshore energy.1

• Experience with PWRs, first-of-a-kind reactor designs, or small modular reactor (SMR) programs.

Role Summary

The Principal Marine Engineer serves as the technical authority for marine engineering across Ocean Atomics' standardized nuclear electric plant and the vessels built to our nuclear-ready guide. Where naval architecture shapes the vessel, this role owns the propulsion, electrical, auxiliary, and control systems that let a compact, water-cooled reactor integrate cleanly onto a maritime platform after delivery.

You will lead the Marine Engineering domain—directing specialist leads across Propulsion, Electrical Generation, Auxiliary & Distribution, and Controls & Communications—from initial concept through class approval and operational deployment. You will define the physical, thermal, and electrical interface boundaries between the conventional hull and the reserved reactor compartment, and convert cross-disciplinary inputs into regulatory-approved, shipyard-ready packages. This is the engineering that brings nuclear power to sea.

The ideal candidate treats interface discipline as the foundation of a clean integration rather than a constraint to work around, and holds technical rigor and collaborative work with class and flag reviewers as two sides of the same job.

What You'll Do

• Lead the marine engineering of the Test and Training Platform (TTP) and follow-on products across their full life cycle, directing the propulsion, electrical, auxiliary, and controls domain leads toward a harmonized machinery plant.

• Define the physical, thermal, and mechanical interface boundaries that separate the conventional maritime hull from the reserved reactor compartment, ensuring clean isolation of vital ship systems.

• Develop and validate the Piping & Instrumentation Diagrams (P&IDs) for high-capacity secondary cooling loops and containment isolation networks engineered for marine hazard conditions.

• Establish the electrical load profiles and high-voltage distribution topologies that accept the nuclear electric plant's power output and synchronize it safely with onshore utility grids.

• Steer the technical submittal strategy through classification society (ABS, LR, etc.) and flag state (USCG, etc.) reviews to secure hull classification and U.S. flag registration.

• Evaluate fabrication tolerances and lifting capability at targeted integration yards so design specifications hold against real shipyard infrastructure constraints.

What You Bring

Required

Role Summary

As Structures Lead, you lead the structural engineering of the hull, heavy foundations, and load-bearing architecture for the vessels that carry Ocean Atomics' nuclear electric plant. You drive the scantlings, material specifications, and structural analysis that clear class society and flag state review, and you ensure the platform side is designed for plant integration from the start — engineered to carry the plant's loads and foundations without mid-cycle rework. From initial concept through class approval, you establish the structural baseline every vessel built to our nuclear-ready guide is engineered against, working closely with naval architecture and our nuclear integration team. This is the structural work that lets nuclear energy scale at sea.

The ideal candidate holds structural margin as a discipline rather than a buffer, finds ways to compress the design cycle without loosening what the analysis has to prove, and treats class and flag review as problem-solving rather than box-checking.

What You'll Do

• Lead the engineering, analysis, and validation of primary and secondary structures under extreme marine and operational loads, from initial concept through class approval.

• Design and optimize hull girder strength, collision barriers, and the shielding support structures that isolate the nuclear electric plant.

• Establish the material selection, plate thickness, and scantling margins that let the platform carry the plant's loads and foundations without mid-cycle re-engineering.

• Develop modular, reproducible structural designs that reduce shipyard fabrication complexity and weld-rejection rates before steel cutting begins.

• Generate the finite element analysis (FEA), structural drawings, and calculations that clear classification society (ABS, LR, etc.) and statutory flag state (USCG, etc.) reviews.

What You Bring

Required

• Bachelor's or advanced degree in Naval Architecture, Structural Engineering, Marine Engineering, or related discipline, or equivalent practical experience.

• Track record leading system-level structural design from concept through class approval. Typically built over 8+ years of focused work in commercial shipbuilding, heavy offshore structures, or large-scale marine energy projects. Depth of experience, design cycles, and successful leadership of major structural projects is valued above years of experience.

• Deep proficiency with marine finite element analysis (FEA) tools and classification society structural rules (ABS, LR, etc.), including fatigue analysis.

Preferred

• Experience with highly regulated or heavy-payload vessel structures.

• Background in modular ship design or repeatable fabrication processes.

• Experience with advanced steel and alloy fabrication methods for marine structures.

Role Summary

As Director of Maritime Workforce, you build the talent supply that makes scaling maritime nuclear possible: the certified craftspeople, technicians, and skilled trades who assemble Ocean Atomics' nuclear electric plant and support the vessels built to carry it. While technical teams design the plant and its surrounding systems, this role secures the people side—ensuring a trained, credentialed workforce is ready as build and activation schedules ramp.

You will develop the domestic talent pipeline OA's model depends on, partnering with organized labor, vocational and technical institutions, and universities to open shared training and recruitment pathways into maritime nuclear work. You'll work across the Maritime Technical, Infrastructure, and Policy directorates so workforce readiness keeps pace with facility timelines and technical milestones, helping establish the training basis for a category of skilled work that doesn't yet exist at scale.

The ideal candidate treats workforce development as infrastructure in its own right, builds durable alliances across institutions that don't naturally align, and holds credentialing as earned capability rather than paperwork.

What You'll Do

• Build and sustain the domestic talent pipeline—craftspeople, technicians, and skilled trades—required to assemble OA's nuclear electric plant and support the vessels built to carry it, from early sourcing through long-term retention.

• Partner with organized labor, vocational and technical colleges, and universities to create shared training and recruitment pathways into maritime nuclear work.

• Work with regulatory bodies and training partners to develop credentialing programs that qualify maritime craftspeople and technicians against nuclear-grade construction and assembly standards.

• Track localized labor-market conditions across target regions and stand up sourcing and training strategies ahead of demand, so staffing keeps pace with build and activation schedules.

• Partner directly with the Maritime Technical, Infrastructure, and Policy Directors so workforce growth aligns with facility activation timelines and technical build milestones.

• Establish the workforce forecasting and readiness metrics that give OA clear visibility into talent supply against the build plan.

What You Bring

Required

• Advanced degree in Human Resources, Industrial Relations, Workforce Development, Business Administration, or a related field.

• Track record of building and scaling large-scale workforce development or human-capital pipelines in commercial shipbuilding, heavy manufacturing, or the energy sector. Typically built over 15+ years of workforce or industrial-relations leadership, though depth of pipeline-building and successful program scaling is valued above years of experience.

• Direct experience designing multi-tiered vocational or technical training programs and moving them from classroom environments to active industrial production.

• Experience negotiating and sustaining organized-labor relationships and building alliances across educational and institutional partners.

Preferred

• Background in highly regulated or safety-critical industries (nuclear, offshore energy, defense manufacturing).

• Familiarity with maritime or shipyard labor environments and relevant credentialing bodies.

• Experience connecting military-to-civilian talent pipelines into commercial maritime or heavy industry.

Role Summary

The Director of Maritime Technical is the technical authority for Ocean Atomics' maritime engineering, owning the structural, machinery, electrical, and auxiliary systems architecture across every marine product line. While policy, workforce, and infrastructure secure the legal and physical pathways, this role defines how vessels are engineered to carry our nuclear electric plant.

Leading the Maritime Technical Division—including the Naval Architecture and Marine Engineering domains—you translate core intellectual property and reactor integration requirements into a standardized Work Breakdown Structure (WBS) that codifies each design for shipyard fabrication. You direct fast-moving design iterations, guide the Principal Naval Architect and Principal Marine Engineer, and set the design criteria that clear classification society and flag state review. This is the role that turns a novel plant-integration concept into buildable maritime assets, and establishes the technical basis every vessel that carries our plant is engineered against—so nuclear energy can scale at sea.

The ideal candidate holds engineering discipline as the foundation of trust while still compressing the design cycle, and treats intense technical friction as collaborative problem-solving rather than a contest of authority.

What You'll Do

• Own the technical strategy for the vessels that carry Ocean Atomics' nuclear electric plant — the structural, machinery, electrical, and auxiliary systems architecture across all marine product lines.

• Direct the translation of core intellectual property and reactor integration requirements into a standardized Work Breakdown Structure (WBS) that codifies each design for shipyard fabrication.

• Guide the Principal Naval Architect and Principal Marine Engineer, coordinating specialized engineering leads across the Naval Architecture and Marine Engineering domains.

• Run the design loops, trade studies, and engineering sprints that mature early concepts into submission-ready packages for critical design reviews.

• Standardize design criteria across disciplines to clear classification society (ABS, LR, etc.) and flag state (USCG, etc.) review, while helping shape international regulatory.

What You Bring

Required

• Advanced degree in Naval Architecture, Marine Engineering, Mechanical Engineering, or a related heavy-industry engineering discipline.

• Track record of directing multi-disciplinary engineering organizations from concept through buildable marine assets. Typically built over 15+ years of engineering leadership in large-scale commercial shipbuilding, offshore energy, or first-of-a-kind (FOAK) marine platform programs. Depth of experience, program complexity, and successful leadership of major marine programs is valued above years of experience.

• Proven ability to translate complex, high-stakes technical designs into standardized, fabrication-ready packages.

Preferred

• Direct experience leading engineering teams through classification society (ABS, LR, etc.) and flag state (USCG, etc.) review.

• International regulatory experience (IMO, foreign flag states).

• Track record of building and scaling engineering teams from the ground up.

Role Summary

The Director of Maritime Infrastructure leads Ocean Atomics' industrial footprint: the deep-water dockyards, heavy fabrication hubs, graving docks, and upland staging areas where our nuclear electric plant is built and sustained. The role carries a dual mandate — identifying and securing the strategic deep-water assets that establish a definitive U.S. manufacturing foundation, then standing up and running operations once those facilities are under Ocean Atomics' control.

Your remit spans site selection through active operation: capital improvement, civil and mechanical integrity, heavy-lift logistics, and the regulatory and physical-security posture that advanced energy manufacturing demands. You'll work across Maritime Technical, Workforce, and Commercial to align yard configurations with plant build and integration requirements and to sequence capital deployment against program milestones. This is the industrial engine that lets nuclear energy scale at sea.

The ideal candidate treats massive physical assets and tight capital discipline as two sides of the same problem, stays composed when industrial timelines collide with program urgency, and reads regulatory review as engineering rather than paperwork.

What You'll Do

• Identify, evaluate, and present the deep-water dockyards, heavy fabrication hubs, and industrial waterfront assets that fit Ocean Atomics' manufacturing model, building toward a durable U.S. foundation.

• Lead operations and maintenance across controlled yards, graving docks, and upland staging areas — civil integrity, mechanical uptime, and site readiness for active build.

• Direct facility lifecycle work as manufacturing scales from prototype toward assembly-line throughput: capital improvement projects, industrial upgrades, and heavy-lift logistics infrastructure.

• Establish the physical-security and regulatory posture each site requires, aligning marine facility security (USCG, etc.), federal environmental controls, and nuclear manufacturing security requirements.

• Partner with Maritime Technical to match yard configurations to plant build and integration requirements, and with Workforce to align site staffing with build tempo.

• Coordinate with Commercial and Finance to sequence and de-risk capital deployment across the U.S. footprint.

What You Bring

Required

• Advanced degree in Civil Engineering, Mechanical Engineering, Construction Management, or a related heavy-industrial discipline.

• Track record of taking complex industrial facilities from site selection through active operation. Typically built over 15+ years directing heavy industrial operations, large-scale shipyard management, or major marine infrastructure builds. Depth of experience, project scale, and successful delivery of large industrial programs is valued above years of experience.

• Direct experience navigating the U.S. industrial and marine regulatory landscape — facility permitting, environmental controls, and physical security for high-consequence sites.

• Demonstrated ownership of capital planning and operating budgets across multiple large-scale sites, balancing asset acquisition against operating discipline.

Preferred

• Experience siting or operating nuclear, defense, or other high-security industrial facilities.

• Background in graving dock, dry dock, or heavy-lift shipyard operations.

• Experience standing up an industrial footprint from a standing start (first-of-a-kind or greenfield build).

Role Summary

As Controls and Communications Lead, you lead the instrumentation, machinery automation, and secure communication architecture for the vessels that carry Ocean Atomics' nuclear electric plant. Where other marine engineering branches handle fluid networks or high-voltage distribution, you build the digital nervous system — the distributed control systems (DCS), network backbones, and telemetry links that let a conventional vessel be engineered for clean plant integration from the start, not retrofitted. You lead these systems from initial concept through class and flag-state approval, working closely with marine engineering, naval architecture, and our nuclear integration team. The cyber-secure interface standards you define become the boundary that lets reactor telemetry integrate into vessel automation safely.

The ideal candidate treats cybersecurity and automation risk as something to characterize and contain rather than pretend away and holds a firm interface boundary without turning collaboration into a standoff.

What You'll Do

• Lead the engineering, configuration, and tuning of distributed control systems (DCS), machinery automation loops, and instrumentation arrays across the vessel.

• Architect and secure the network backbones, telemetry links, and data transmission pathways that carry vessel and machinery data, from initial concept through deployment.

• Define the cyber-secure interface standards and hardware/software protocols that let conventional vessel automation safely accept reactor telemetry when the plant is integrated.

• Design the monitoring bridges and data links that connect conventional marine control stations with reactor safety systems, working with our nuclear integration team.

• Develop modular, reproducible control topologies that reduce shipyard wiring and integration complexity and improve system resilience.

• Generate the control logic diagrams, network architecture topologies, cybersecurity risk assessments, and technical data packages that clear classification society (ABS, LR, etc.) and statutory flag state (USCG, etc.) reviews.

What You Bring

Required

• Bachelor's or advanced degree in Electrical Engineering, Computer Engineering, Systems Engineering, or related discipline, or equivalent practical experience.

• Track record leading system-level controls, automation, or industrial network design from concept through deployment. Typically built over 8+ years in marine automation, distributed control systems, or secure industrial/cyber-physical networks for commercial vessels, naval ships, or offshore energy assets. Depth of experience, design cycles, and successful leadership of major controls projects is valued above years of experience.

• Deep proficiency in industrial network architectures (e.g., Modbus, Profibus, EtherNet/IP), PLC/DCS programming, and maritime cybersecurity frameworks (e.g., IEC 62443, ABS cyber requirements).

• Working command of classification society rules for automated and computerized systems (ABS, LR, etc.) and flag state regulatory processes.

Preferred

• Experience with cyber-physical security for safety-critical or highly regulated systems.

• Background in modular ship design or repeatable fabrication and integration processes.

• Cross-functional experience partnering with marine engineering, electrical, and naval architecture teams on integrated vessel designs.
