Nuclear System Integration Eng

Ocean Atomics

2d•$95,000 - $220,000

About The Position

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.

Requirements

Track record of defining and managing interfaces between a major system and its host platform, from design through construction. Typically built over 5+ years of integration, installation, or interface engineering — naval/marine, large-scale nuclear construction, or comparable regulated platform work. Depth of experience and successful resolution of complex interface conflicts is valued above years of experience.
Strong understanding of mechanical integration — foundations, alignment, hull/bulkhead penetrations, tolerance stack-up, thermal growth, and shock/vibration in a marine environment.
Working knowledge of fuel handling operations and equipment, including access, transfer routes, and refueling/defueling sequences.
Familiarity with shipyard construction methods, including modular build, installation sequencing, and heavy lift/rigging.
Bachelor's degree in Mechanical Engineering, Naval Architecture & Marine Engineering, Nuclear Engineering, or equivalent practical experience.

Nice To Haves

Experience with naval nuclear propulsion, transportable, or floating reactor programs.
Familiarity with spent fuel handling, cask/transfer interfaces, and refueling outage logistics.
Working knowledge of CAD/PLM and dimensional management tools.

Responsibilities

Define, document, and own the physical and functional interfaces between the reactor plant and the ship and shipyard.
Develop and maintain interface control documents, and drive their resolution across reactor, structural, and shipyard disciplines.
Design the fuel handling arrangement and equipment interfaces — access, transfer paths, active cooling, lift points, and refueling and defueling sequences.
Support modularization, installation sequencing, alignment, and foundation design so the plant can actually be built and installed.
Ensure interfaces hold up under shock, vibration, thermal growth, and the marine environment across operating and casualty conditions.
Document integration results and justify methodology for the licensing or certification process.
Coordinate with reactor, systems, and structural teams to confirm constructability and maintainability before steel cutting begins.
Provide integration inputs to build, test, and commissioning teams.
