<div>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. </div>Senior Structural Civil EngineerRadiant is looking for a Senior Structural Civil Engineer to design and develop reliable metallic and cement structures for reactor systems, including shielding and foundation structures. You will design safety critical systems that withstand natural loads (seismic, flood, wind) as well as soil interactions.
