Maritime Nuclear Systems Engineer

Ocean Atomics; Bethesda (MD); On-site; USD 120,000 - 160,000; Full time

Job summary

Ocean Atomics is building nuclear-powered maritime infrastructure and seeks a Nuclear Systems Integration Engineer to design and manage cross-boundary systems for maritime nuclear plants, ships, and shipyards. You will ensure performance, safety, manufacturability, and regulatory compliance across reactor, hull, and supporting systems.

You’ll lead interface control, coordinate across naval architecture, reactor engineering, safety/licensing, and shipyard teams, develop interface documents,

Qualifications

• Bachelor's degree in Mechanical, Marine, Naval, Nuclear, or related engineering.
• 5+ years of experience in mechanical design and systems integration for complex engineered systems.
• Demonstrated experience managing technical interfaces across multiple engineering disciplines.
• Working knowledge of structural and mechanical design principles, including dynamic and accident loading.
• Familiarity with safety analysis methods and regulated-industry design controls.
• Strong written technical documentation skills (specifications, interface control documents).
• A hustle mindset: bias toward action, comfort with ambiguity, and relentless follow-through.

Responsibilities

• Perform mechanical design and integration of cross-boundary systems including reactor/fuel handling equipment, plant-to-hull structural interfaces, shielding integration, and supporting auxiliary systems.
• Define and manage interface requirements between the reactor, ship systems (structure, propulsion, HVAC, electrical, fluid systems), and shipyard construction/maintenance processes.
• Assess and design for ship-specific hazards affecting the nuclear plant, including collision, grounding, flooding, fire, motion/sea-state loads, and shock/vibration.
• Develop and maintain interface control documents, system specifications, and integration plans.
• Coordinate across naval architecture, reactor engineering, safety/licensing, and shipyard production teams to resolve cross-discipline conflicts.
• Support safety case development and hazard analyses for integrated systems.
• Review designs for constructability, installation sequencing, and in-service maintenance and refueling access.
• Ensure compliance with applicable classification society rules, IMO/maritime regulations, and nuclear regulatory requirements.
• Lead, mentor, and develop teams of engineers responsible for mechanical, structural, civil, and nuclear system design and operation.
• Establish and maintain a high-performance culture centered on nuclear safety, technical excellence, accountability, and continuous improvement.
• Recruit, onboard, and develop engineering talent to support organizational growth and long-term engineering expertise.
• Conduct performance evaluations, career development planning, and technical mentoring for engineering staff.
• Support the expansion of Ocean Atomics through effective knowledge transfer, agile prioritization of critical business needs, and collaboration across functional company areas to build a scalable organization.
• Ensure engineering products meet rigorous nuclear industry standards and quality requirements.
• Provide technical leadership during emergent operational events and high-consequence engineering challenges.
