About The Position

Ocean Atomics (OA) 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 is to scale nuclear energy and power generations. Our vision is 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

Required Experience defining and managing interfaces between a major system and its host structure or platform
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
Ability to own interface control documentation and coordinate across reactor, naval architecture, and shipyard trades
Ability to work on a close, rapidly iterative design team
Strong technical writing skills

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 disciplines
Design the fuel handling arrangement and equipment interfaces, access, transfer paths, active cooling, lift points, and refueling/defueling sequences
Support modularization, installation sequencing, alignment, and foundation design to ensure the plant can be built and installed
Ensure interfaces accommodate shock, vibration, thermal growth, and the marine environment across operating and casualty conditions
Rigorously document integration results and justify methodology in support of the licensing or certification process
Coordinate with reactor, systems, and structural teams to confirm constructability and maintainability
Provide integration inputs to build, test, and commissioning teams
