Neutronics Jobs in Washington, DC (NOW HIRING)

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.

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.

Scale nuclear energy. Power generations.

A maritime commons thriving with abundant, economical, modern, and safe nuclear-powered activity — built, serviced, and staffed by re-industrialized American shipyards and people.

Our Neutronics Engineers will design, simulate, optimize, and document the neutronic aspects of our reactor core.

• Maintain and expand core design simulations, including simple and complex models covering criticality, transmutation/decay, shutdown margin/control rod worth, kinetics parameters, frequency domain stability, etc.

• Work with larger core design team to develop coupled multiphysics models supporting normal and transient behavior

• Analyze and optimize core performance in support of trade studies, licensing documentation, and product optimization

• Rigorously document design results

• Justify calculation methodologies and their V&VV in support of the licensing process

• Provide core design information in transient analysis studies

• Provide core information to simulator and operational physics teams

• Perform shielding and activation analysis supporting the design

• Experience building and running sophisticated core neutronics simulations

• Strong understanding of nuclear design couplings, challenges, tradeoffs

• Ability to work on a close, rapidly iterative design team

• Strong working knowledge of two or more common reactor simulation tools

• Highly skilled with computers

• Strong technical writing skills

• Bachelor's degree in Nuclear Engineering or Engineering Physics

• 5+ years professional experience designing cores

• Strong working knowledge of many common deterministic and stochastic neutronics tools (e.g. MCNP, OpenMC, CASMO/SIMULATE, VERA, DRAGON, etc.)

Don't meet every bullet? We'd still like to hear from you. If you're excited by the mission and most of this resonates, apply. 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.

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.
