From Radiant Industries's posting. “We” and “our” refer to the employer.
Radiant is an El Segundo, CA-based startup building the world’s first mass-produced, portable nuclear microreactors. The company’s first reactor, Kaleidos, is a 1-megawatt, fail-safe microreactor that can be transported anywhere power is needed and run for up to 5 years without refueling. Portable nuclear power with rapid-deploy capability can replace similar-sized diesel generators and provide critical asset support for hospitals, data centers, remote sites, and military bases.
Radiant’s unique, practical approach to nuclear development leverages modern software engineering to rapidly deliver safe, factory-built microreactors that use existing, well-qualified materials. Founded in 2020, Radiant is on track to test its first reactor at the Idaho National Laboratory this summer, with initial customer deliveries beginning in 2028.
Radiant is seeking a driven
Senior Thermal Modeling & Analysis Engineer to own high-fidelity CFD and thermal modeling for the Kaleidos microreactor. You will analyze heat generation and transport, high-temperature gas flow, and thermal interactions across reactor systems, cooling systems, shielding, and surrounding hardware under steady-state, transient, and off-normal conditions.
Your work will directly influence system architecture, component design, material selection, operating limits, test planning, and safety margins. You will work across mechanical, fluid systems, nuclear, structures, controls, and test engineering to develop validated analytical tools that support the commercialization of the first mass-produced nuclear reactor.
