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 failsafe microreactor that can be transported anywhere power is needed and run for up to five years without the need to refuel. 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 utilizes modern software engineering to rapidly achieve safe, factory‑built microreactors that leverage existing, well‑qualified materials. Founded in 2020, Radiant is on track to test its first reactor next year at the Idaho National Laboratory, with initial customer deliveries beginning in 2028.

We’re building a new team to own Radiant’s internal data infrastructure, executive analytics, and AI capabilities. As the Staff Dev Ops Engineer, you’ll own the infrastructure that powers our data platform—ensuring reliability, security, and scalability for the systems that connect Finance, HR, Supply Chain, and Recruiting.
