Job description

About Radiant

Radiant is an El Segundo, CA-based company building the world's only mass-produced, transportable nuclear microreactors. The U.S. grid is under growing strain, with power demand accelerating, driving higher utility costs, rising carbon emissions, and interconnection backlogs. Radiant has a solution, transportable, on-site power. Our first reactor, Kaleidos, is 1 megawatt: small enough to be factory-built, transported by land, sea, or air, and deployed wherever power is needed. 1 MW can power 1000 homes for five years. Ship it back and we refuel for a 20 year operating life. We made energy a product that can be used for critical infrastructure like military bases, data centers, hospitals, and remote sites, as well as the commercial main street businesses that keep America running. Founded in 2020, Radiant is under contract to deliver power to the U.S. Army, Navy and Air Force and has signed pre-order agreements with Equinix, with deployments beginning in 2028.

About The Role

Radiant is seeking a highly engaging and effective leader for our regulatory and licensing team. The Director of Regulatory Affairs will oversee licensing engagement, strategy, process, and execution with the U.S. Nuclear Regulatory Commission (NRC).

The ideal candidate is experienced working with government agencies and officials in risk-informed regulations, is determined to execute on how things should be done vs. how they’ve always been done and can engage deeply with our engineering organization to produce a foundationally safe product rather than one that simply checks regulatory boxes.
