Full Job Description
ABOUT RADIANT Radiant is an El Segundo, CA-based startup building the world’s first mass-produced, portable nuclear microreactors. The company’s first reactor, Kaleidos, is a 1-megawatt, fail-safe microreactor that can be transported anywhere power is needed and run for up to 5 years without refueling. Portable nuclear power with rapid-deploy capability can replace similar-sized diesel generators and provide critical asset support for hospitals, data centers, remote sites, and military bases. Radiant’s unique, practical approach to nuclear development leverages modern software engineering to rapidly deliver safe, factory-built microreactors that use existing, well-qualified materials. Founded in 2020, Radiant is on track to test its first reactor at the Idaho National Laboratory this summer, with initial customer deliveries beginning in 2028. ABOUT THE ROLE Radiant is seeking a Hardware-in-the-Loop (HIL) Engineer to support the development and maintenance of Radiant’s NI PXI-based HIL system for Kaleidos. You will work closely with senior engineers to assist in hardware integration, testing, and validation of critical systems. This role is ideal for someone with foundational experience in HIL systems and a desire to grow their skills in real-time testing, automated validation, and electrical integration within a collaborative team environment. You will have the opportunity to contribute to the development of electrical integration systems that support the first high-temperature gas-cooled portable microreactor ever commercialized. RESPONSIBILITIES AND DUTIES: - Assist in designing, building, and maintaining HIL test bench systems. - Help configure test hardware, including power supplies, actuators, and sensor mapping. - Support communication and integration with Digital Twin systems. - Assist senior engineers with assembling and debugging HIL hardware and harnesses. - Execute test procedures, collect data, and support analysis. - Document test results, procedures, a
