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.).

The ocean is the largest undeveloped frontier on earth, and the next chapter of abundant energy will be written at sea. We're building the infrastructure to power it.
About Ocean Atomics (OA)
Ocean Atomics is an American company designing, licensing, and assembling a standardized nuclear electric power plant and the surrounding support systems for maritime applications. We will install these plants on any vessel built to our nuclear-ready standards, and will provide end-to-end sustainment in our planned nuclear lifecycle dockyard. We will help develop the licensed operators to unlock this new capability for your energy intensive application at sea. To move fast and to lead the creation of this new market, we are leveraging the compact, proven systems enabled by water-cooled reactors.
Our mission

Role Summary
Our Marine Engineers perform marine engineering activities across Ocean Atomics' standardized nuclear electric plant and the vessels built to our nuclear-ready guide. Where naval architecture shapes the vessel, these roles develop the propulsion, electrical, auxiliary, and control systems that let a compact, water-cooled reactor integrate cleanly onto a maritime platform after delivery.
You will develop the 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.
We are hiring into this area for a variety of levels based on experience.
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
Advanced degree in Marine Engineering, Mechanical Engineering, or a related heavy power or propulsion engineering discipline.
Track record of leading complex marine machinery and power systems from concept through regulatory approval and deployment. High level applicants have built over 12+ years of engineering leadership in commercial shipbuilding, offshore energy, or first-of-a-kind marine platform design. Depth of experience, design cycles, and successful leadership of major marine engineering projects is valued above years of experience.
Direct experience leading multidisciplinary engineering teams through classification society (ABS, LR, etc.) and flag state (USCG, etc.) review processes.
Preferred
Experience with high-voltage marine power systems, utility grid integration, or hazardous fluid thermal management.
Exposure to nuclear quality assurance frameworks (ASME Section III, N-Stamp) or complex containment systems.

The ocean is the largest undeveloped frontier on earth, and the next chapter of abundant energy will be written at sea. We're building the infrastructure to power it.
About Ocean Atomics (OA)
Ocean Atomics is an American company designing, licensing, and assembling a standardized nuclear electric power plant and the surrounding support systems for maritime applications. We will install these plants on any vessel built to our nuclear-ready standards, and will provide end-to-end sustainment in our planned nuclear lifecycle dockyard. We will help develop the licensed operators to unlock this new capability for your energy intensive application at sea. To move fast and to lead the creation of this new market, we are leveraging the compact, proven systems enabled by water-cooled reactors.
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
What You’ll Do
Electrical System Design
Develop the electrical power system design for the nuclear plant from functional requirements through detailed one-line diagrams, schematics, elementary and connection diagrams, cable schedules, and equipment specifications.
Establish and document the design basis for each system and load, including voltage and frequency, load classification, safety class and division assignment, design life, duty cycle, and applicable codes and standards.
Design safety-related and non-safety-related distribution: switchgear, load centers, motor control centers, vital AC and DC systems, batteries, chargers, inverters, and their protection.
Specify power supplies to reactor plant loads including control rod drive mechanisms, coolant pumps, motor-operated valves, heat tracing, and instrument and control power, and define the isolation between safety-related and non-safety-related circuits.
Perform protective device coordination and selectivity, and specify protection and control schemes consistent with the plant's safety and availability requirements.
Produce design specifications, design reports, and the supporting calculation packages that flow to suppliers and to the certifying authority.
Lead design reviews at concept, preliminary, critical, and final design stages. Drive resolution of action items and design changes through formal configuration control.
Vessel Integration
Define the boundary and interface between the nuclear plant electrical system and the vessel's generation and distribution, including which loads are served from which source under each operating and casualty condition.
Define equipment arrangement, mounting, and access requirements within the constraints of the vessel hull, deck structure, and surrounding plant systems.
Design equipment mounts, restraints, and cable support to transfer loads into the ship's primary structure without compromising either the equipment or the hull.
Route cable and define penetration treatment across watertight, fire, and shielding boundaries while preserving divisional separation and boundary integrity.
Coordinate with naval architecture and structural engineering on deck accelerations at equipment locations, weight and center-of-gravity impact, and the load path from equipment to hull.
Resolve interface issues with adjacent disciplines: mechanical, piping, instrumentation and control, HVAC, shielding, and maintenance access.
Support outfitting sequence planning so that equipment can be installed, terminated, tested, and commissioned within the shipyard build strategy.
What You Bring
Required
Bachelor's degree in Electrical Engineering, Electrical Engineering Technology, or a closely related discipline.
10+ years of electrical power system design experience on nuclear, marine, utility, or other code-governed power systems, with at least 5 years on nuclear systems.
Demonstrated working knowledge of safety-related (Class 1E) electrical design requirements, including redundancy, divisional independence, single-failure criterion, and separation.
Strong proficiency with power system analysis software (ETAP, SKM, EasyPower, or equivalent), including load flow, short-circuit, protective device coordination, and motor-starting analysis.
Direct experience producing design reports, calculation packages, or equivalent code-compliant analyses that have been reviewed by a third party or regulator.
Experience sizing and specifying DC systems and uninterruptible power: station batteries, chargers, inverters, and vital AC and DC distribution.
Working knowledge of cable and raceway design: ampacity and derating, voltage drop, raceway fill, separation and segregation, and penetration treatment.
Working knowledge of equipment qualification principles, environmental, seismic and shock, and vibration, and of how qualification evidence is assembled and defended.
Preferred
Master's degree in Electrical Engineering or a related discipline.
