Job description

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
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.
  • Generate the mechanical schematics, calculations, 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 Marine Engineering, Mechanical Engineering, or related discipline, or equivalent practical experience.
  • Track record leading system-level propulsion design from concept through deployment. Typically built over 8+ years of focused work in maritime propulsion, heavy machinery design, or comparable regulated platform work. Depth of experience, design cycles, and successful leadership of major propulsion projects is valued above years of experience.
  • Working command of classification society machinery rules (ABS, LR, etc.) and flag state regulatory processes.

Preferred
  • Experience with highly-regulated vessel propulsion systems.
  • Background in modular ship design or repeatable fabrication processes.
  • Cross-functional experience partnering with naval architecture and structural teams on integrated designs.

Export control notice
This position involves access to information subject to U.S. export control laws (ITAR and/or EAR). Any offer is contingent on your ability to work in compliance with these laws, and Ocean Atomics LLC may apply for U.S. government authorization where needed. 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.
Ocean Atomics LLC is an equal opportunity employer.
We are committed to a workplace free of discrimination and do not discriminate on the basis of race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, genetic information, veteran status, or any other characteristic protected by applicable law.
