Senior Hardware-in-the-Loop (HIL)Engineer El Segundo, California, United States

Senior Hardware-in-the-Loop (HIL) 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 Senior Hardware-in-the-Loop (HIL) Engineer to own and develop Radiant's NI PXI-Based HIL system for Kaleidos. You will be responsible for the end-to-end development from requirements gathering, hardware sourcing and development, integrating HIL into our software systems, and completing through commission. The ideal candidate will have extensive experience with NI PXI hardware, real-time testing, and automated validation frameworks. You will also own harnessing design from an early stage, component selection, qualification through production. The ideal candidate is comfortable working both autonomously and with an interdisciplinary team, as well as in the early design architecture phases of development. You will have the opportunity to build electrical integration systems from the ground up that will drive success towards the first successful fuel demonstration of a new commercial nuclear reactor design in over 50 years.
