Design
El Segundo, CA, USA
Posted on Feb 20, 2025
Radiant is an El-Segundo, CA-based clean energy startup building a nuclear microreactor. A climate-friendly alternative to diesel generators, Radiant's Kaleidos 1MW microreactor will be the world's first portable, zero-emissions power source that works anywhere. We plan to test our development reactor by 2026 and if successful, it will be the first new commercial reactor design to achieve a fueled test in over 50 years. Radiant's goal is to bring one of the world's first factory-constructed microreactors to market. Our microreactor can bring power to remote parts of the world and provide backup power for life-saving applications in hospitals or disaster-relief scenarios.
Senior Motor Design Engineer
Radiant is seeking a talented Senior Motor Design Engineer to design and develop an alternator for the nuclear-driven, high-speed power generator. Responsibilities include but are not limited to the design of active parts, and the structural and thermal analysis of high-speed generators.You will collaborate with engineers cross-functionally and partner closely with the Power Conversion and Electrical Systems team responsible for converting mechanical energy to electrical to be delivered to customers safely and reliably.
