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 an Engineering Manager, Integration & Test, to lead the electrical engineering team responsible for test infrastructure and system integration for Kaleidos, Radiant's commercial microreactor unit targeted for deployment in 2028. You will manage a team of electrical engineers while owning cross-functional stakeholder relationships and driving execution from early architecture through hardware bring-up, testing, and commissioning. The ideal candidate brings deep electrical engineering expertise, proven people management experience, and a track record of delivering complex hardware programs on tight timelines.
Responsibilities & Duties
Radiant compensates people for impact and invests in those who continue to raise the bar. Radiant’s new hire compensation package includes base salary, substantial equity grants, and comprehensive health benefits. Total compensation and level are determined through a rigorous evaluation of interview performance, experience, education, and qualifications, and are designed to support continued growth as scope, responsibility, and impact expand at Radiant.
