Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
Manage the full recruitment lifecycle from sourcing niche technical talent to closing offers. Develop talent market reports and help build the foundational recruiting processes and tools for the company.
Requires a bachelor's degree and 0-2 years of experience in recruiting, sales, or sourcing. Candidates must demonstrate a bias toward action, curiosity about hardware/nuclear/AI, and the ability to engage with technical candidates.
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.
Run your own reqs from open to close, building the pipeline, screening candidates, coordinating interviews, and getting offers signed.
Find niche talent markets for specialized engineering roles in places like GitHub repos, arXiv papers, technical mailing lists, tech foundation communities, conference speaker rosters, and academic programs.
Create talent market reports based on research you drive to help make better-informed recruiting strategies.
Coordinate interviews and help facilitate hiring team debriefs to keep decisions moving quickly.
Sit in on offer conversations with senior recruiters and learn how strategy and closing work in practice.
Help shape how Radiant recruits; the processes, tools, and 3rd party platforms you help build and adopt now become the foundation the team scales on.
Get hands-on exposure to hiring across multiple technical functions: electrical, mechanical, software, and more.
Bachelor's degree from an accredited university.
0–2 years of experience in recruiting, sales, sourcing, or coordination, or you've picked it up on your own and can point to something that proves it.
Something outside the classroom that shows real team influence, a club you led, student government, a project you built, a sport you competed in, or work you volunteered for.
A genuine pull toward hardware, nuclear, physics, or AI/ML; you don't need an engineering background, just real curiosity.
A bias toward action: you move quickly, problem-solve on the fly, and know when to raise your hand for help.
You're able to hold a genuine conversation with technical candidates, curious enough to ask good questions, and honest enough to admit when something's outside your depth.
Bachelor's degree in a STEM-related major is a plus.
Any prior exposure to hardware, software, engineering, or tech recruiting, even informally.
Comfort picking up new tools such as LinkedIn Recruiter, ATS, sourcing, LLM platforms, even without direct prior experience.
