Senior Turbomachinery Engineer

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.

Radiant is seeking a highly motivated Turbomachinery Engineer to join our engineering team to own the power generation and/or primary cooling turbomachinery of our Kaleidos product. This role involves performing the mechanical design and analysis of high-speed rotating machinery including compressors, turbines, and pumps for high-temperature applications. The ideal candidate will have a strong background in mechanical design, structural and thermal finite element analysis (FEA), rotordynamic simulations, and bearing selection and integration, along with hands-on experience building physical hardware.
