About Radiant
Radiant is an El Segundo, CA-based startup building the world’s first mass-produced, portable nuclear microreactors. Rising energy demand is straining the U.S. grid and driving up utility costs, emissions, and interconnection backlogs. Radiant decentralizes energy, producing power close to where it’s used. Its first reactor, Kaleidos, is a factory-built, 1-megawatt, fail-safe microreactor that can be transported by land, sea, or air and runs up to 5 years without refueling. Deployed locally without a decade-long build or permitting fight, Kaleidos provides independent power for critical infrastructure like military bases, data centers, hospitals, and remote sites. Founded in 2020, Radiant is under contract to deliver power to the U.S. Army, Air Force, Navy, and has pre-order agreements with Equinix, with deployments beginning in 2028.
About the Role
Radiant is looking for an Indirect Procurement Associate to support sourcing and procurement of indirect goods and services — Facilities, IT, Professional Services, MRO, consumables, and R&D collaborations. This is a hands-on role for someone with strong technical instincts who wants to build skills in supplier evaluation, negotiation, and contract support. You'll work alongside Engineering, Operations, Finance, and Production, and will be paired with more senior procurement staff to develop your commercial and negotiation skill set.
Responsibilities & Duties
Support sourcing efforts for indirect categories (IT, Professional Services, MRO, consumables, R&D collaborations) by gathering technical requirements and evaluating supplier capability against Radiant's engineering needs.
Assist with drafting and reviewing SOWs, NDAs, and PO terms; help prepare negotiation positions for MSAs and licensing agreements under guidance from senior staff.
Help manage facilities/MRO procurement tasks — coordinating with vendors on maintenance, repairs, equipment, and small lab build-out needs.
Track purchase orders through the procure-to-pay cycle, flagging delays or technical mismatches early.
Act as a day-to-day point of contact for select, lower-complexity suppliers, escalating high-stakes commercial matters to senior procurement staff.
Contribute technical judgment to cost and quality trade-off discussions.
Help identify supply chain risks from an engineering/technical perspective (e.g., part obsolescence, service quality issues).
Support process documentation and improvement efforts.
Required Qualifications & Skills
Bachelor's degree in Mechanical Engineering (or closely related engineering field) strongly preferred, Supply Chain or similar degrees considered
1–3 years of relevant experience; prior procurement/sourcing experience is a plus but not required.
Strong technical/mechanical aptitude and genuine interest in the commercial side of engineering (supplier selection, cost trade-offs, contracts).
Good analytical and organizational skills; comfortable learning negotiation and contract fundamentals on the job.
Strong written and verbal communication skills.
Comfortable with ERP/MRP systems and standard office software (or willing to learn quickly).
Occasional travel to supplier locations (up to 20%).
Desired Qualifications
Exposure to Facilities, MRO, IT, or Professional Services sourcing.
Coursework or interest in quality systems (ISO 9001, AS9100).
