Supplier Development 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 Supplier Development Engineer responsible for the onboarding, qualification, auditing, and ongoing development of suppliers to ensure compliance with applicable nuclear and industrial quality codes and standards. This role will help build a world-class, compliant, and reliable supply base capable of delivering high-quality, safety-critical components for our micro reactor systems. The ideal candidate is detail-oriented, collaborative, and eager to grow subject matter expertise within highly regulated industries.
