Nuclear Safety Engineer

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 Owns the safety case and probabilistic risk assessment (PRA) for a marine reactor and its supporting systems, demonstrating that the plant meets safety requirements across normal, off-normal, and accident conditions throughout the vessel's operating life. Beyond just analyzing, this role will iterate closely with the engineering team to establish the optimal architecture of systems. What You'll Do Develop and maintain the safety case and supporting PRA models for the reactor and associated ship systems. Actively use the PRA and underlying data to inform and optimize the engineering design of the overall system throughout the design phases Identify initiating events and failure modes, perform hazard and accident analyses, and quantify risk to verify compliance with safety acceptance criteria. Support design reviews and trade studies, translating safety findings into requirements and design changes for the secondary and balance-of-plant systems. Maintain safety documentation and traceability through configuration changes, operational feedback, and as-built modifications. Interface with regulators, classification societies, and internal review boards, and prepare licensing and certification deliverables. What You Bring Bachelor's degree in nuclear, or mechanical (advanced degree preferred). Demonstrated experience developing safety cases and PRA for nuclear systems. Proficiency with PRA methods and tools (e.g., fault/event tree analysis, reliability data, SAPHIRE or equivalent). Working knowledge of nuclear safety standards and regulatory frameworks (NRC, IMO, naval, or international equivalents). Export control notice This role involves access to information subject to U.S. export control laws, including unclassified nuclear technology governed by the U.S. Department of Energy under 10 CFR Part 810. Depending on a candidate's status, access may require DOE authorization, which Ocean Atomics may apply for. Any offer is contingent on your ability to work in compliance with these requirements. We evaluate all applicants regardless of citizenship or national origin, except where required by law. Why this matters Every industry on Earth needs scalable, clean energy, and the ocean is the ideal place to unlock it. Joining Ocean Atomics means building real, lasting infrastructure — the kind that powers generations. The world needs abundant energy. Let's make it happen.
