Radiation Shielding Engineer

About the role

This role is part of a team designing and analyzing radiation shielding for the reactor and ship at Ocean Atomics. It involves working with radiation transport codes, performing calculations, and coordinating with structural, layout, and construction teams.

Responsibilities

• Design and analyze radiation shielding for the reactor, primary systems, and surrounding compartments using transport, Monte Carlo, and hybrid methods.
• Perform activation, dose-rate, and source-term calculations across operating, shutdown, and accident conditions to verify compliance with occupational and public dose limits.
• Study historical ship and other unconventional shielding solutions and bring applied history into our design.
• Develop shielding arrangements optimized for shipboard installation: modular geometries, manageable component weights, access for handling equipment, and compatibility with build and outfitting sequences.
• Cook with the structural, layout, and construction teams to integrate shielding into the ship arrangement and resolve weight, space, and installation trade-offs.
• Document shielding designs, analyses, and as-built configurations, and support design reviews, licensing, and certification deliverables.

Requirements

• Bachelor's degree in nuclear engineering required (advanced degree preferred).
• Experience designing and analyzing radiation shielding for reactor or other high-radiation systems.
• Proficiency with radiation transport codes (MCNP, SCALE, etc.) and shielding/source-term methods (i.e. FW-CADIS).
• Familiarity with shipboard or other space- and weight-constrained installation environments.

Company Information

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 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.

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.
