Radiant Industries is an El Segundo, CA-based startup developing Kaleidos, a portable, containerized nuclear microreactor. Portable nuclear power with rapid deploy capability can replace diesel generators used today to provide critical asset support for hospitals, datacenters, and military bases or to power microgrids at remote sites. Radiant’s unique practical approach to nuclear development utilizes modern software engineering to rapidly achieve safe, factory-constructable microreactors leveraging existing, well-qualified materials. Radiant is on a fast track to demonstrate the first fueled operation of a new commercial nuclear reactor design, just four years from now.
Radiant is seeking a highly motivated nuclear engineer for an opportunity to work with mentorship and guidance from experienced nuclear professionals in a fast-paced startup environment. The candidate will be responsible for various aspects of nuclear design and analysis as priorities shift and expertise is gained.
