About the role
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 hiring a Business Development Manager to be based out of El Segundo, California. Reporting to the Chief Revenue Officer, this role is for someone early in their BD career who is hungry, scrappy, and ready to build a pipeline from scratch. There are no warm leads handed to you here. We need someone who can independently identify potential customers, get in the door, and drive commercial conversations forward in a market our product will be the first to create. This is fundamentally a sales role for someone who wants to prove themselves. The right candidate has enough experience to know how to run a deal process, but is early enough in their career that closing their first major agreements in an emerging industry would be a defining moment. If you are competitive, curious, and want to do some of the most meaningful commercial work of your career, we want to hear from you.
Responsibilities & Duties: Independently source and qualify leads across commercial verticals including C&I, utilities, remote communities, and defense. Lead client conversations from first contact through discovery, proposal, and term sheet. Support negotiation of commercial documents toward binding agreements. Build and maintain a pipeline from zero, with an emphasis on quality over volume. Develop tailored proposals, grant letters, and external communications. Learn the fundamentals of siting, licensing, permitting, and project finance well enough to speak credibly with customers and identify what it takes to get a deal across the finish line. Act as an ambassador for Radiant's mission, values, and brand in every customer interaction. Required
