Strategic Sourcing Lead - Nuclear Hardware & NPI, Equity

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 proactive and technically-minded Strategic Sourcing Manager to lead the discovery, qualification, and development of new suppliers and manufacturing technologies in support of our micro-reactor program. This role is foundational to expanding Radiant's supply base into new commodities, processes, and capabilities as our designs mature. Unlike a traditional buyer role, this position is heavily front-end weighted — finding the right suppliers before a part exists in production, matching engineering intent to real-world manufacturing capability, and shepherding new suppliers and parts from concept through qualification and into reliable, on-time delivery. You will work closely with Engineering, Supplier Development Engineers (SDEs), Quality Assurance, and Operations to build Radiant's supplier ecosystem from the ground up. Responsibilities & Duties: Supplier Discovery : Proactively identify and research new potential suppliers and manufacturing technologies across domestic and (where permissible) international markets, including specialized, niche, or emerging process capabilities relevant to nuclear-grade hardware. Design-to-Supplier Matching : Partner with Engineering to interpret drawings, specifications, and material requirements, and translate them into supplier search criteria — matching part complexity, tolerances, materials, and process needs to real supplier capability. Supplier Vetting & Qualification : Lead initial supplier vetting, including capability assessments, facility questionnaires, and preliminary risk screening, in coordination with SDEs and Quality on technical and quality qualification. Onboarding : Own the end-to-end onboarding process for new suppliers — from first contact through NDA, capability review, and entry into Radiant's approved supplier base. R&D & New Technology Sourcing : Research and evaluate emerging manufacturing technologies and processes (e.g., additive manufacturing, novel joining/forming methods) that could unlock new sourcing pathways or de-risk critical components. New Part Introduction (NPI) Support : Act as the commercial and program-management thread for new parts through their qualification lifecycle — coordinating purchase order issuance, first articles, prototype builds, and pilot runs between the supplier, Engineering, and Quality. Supplier PM through Production : Once a supplier/part is qualified, manage the transition into steady-state delivery — issuing and managing purchase orders, tracking schedule, resolving early production issues, and ensuring a smooth handoff toward on-time, recurring delivery. Cross-functional Collaboration : Work seamlessly with SDEs on technical/quality qualification, with Engineering on design intent and make/buy decisions, and with Procurement/Planning on transitioning qualified suppliers into the standard sourcing and PO process. Market Intelligence : Maintain awareness of supply market trends, capacity constraints, and geopolitical risk factors affecting candidate suppliers and technologies, particularly for nuclear-grade and DFARS-relevant materials and processes. Process Improvement : Help build and refine Radiant's supplier discovery, vetting, and onboarding processes and tools as the sourcing function matures. Purchase Order Support : Assist with placing purchase orders and monitoring purchase order health (open PO aging, delivery status, discrepancy resolution) as needed to support program timelines. Supplier RCCA Support : Support Root Cause Corrective Action (RCCA) activities with suppliers as issues arise, coordinating with SDEs and Quality to drive timely resolution and closure. Deliverables: A growing pipeline of qualified, capable suppliers matched to Radiant's evolving design needs. Successfully onboarded new suppliers meeting technical, quality, and commercial requirements. New parts/technologies moved through qualification and into reliable production delivery. Supplier capability assessments and vetting documentation supporting sourcing decisions. Identified and evaluated new manufacturing technologies with clear recommendations for adoption. Strong collaborative relationships internally (SDE, Engineering, QA, Procurement, Operations) and externally (new suppliers). Required Qualifications & Skills: Bachelor's degree in Supply Chain Management, Engineering, Business Administration, or a related field. 3–8 years of experience in strategic sourcing, supplier development, or new product introduction, preferably within manufacturing, aerospace, defense, or energy sectors. Demonstrated ability to read and interpret engineering drawings and technical specifications. Strong track record of identifying and qualifying new suppliers, particularly for complex or low-volume/high-mix components. Excellent analytical, research, and problem-solving skills. Strong interpersonal and communication skills (written and verbal), including comfort engaging directly with supplier engineering and operations teams. Proficiency with ERP/MRP systems and standard office software. Ability and willingness to travel to supplier locations for capability assessments and audits (up to 20%–40% depending on program phases). Desired Qualifications & Skills: Experience in the nuclear energy, aerospace, or defense industries, or working with nuclear codes and standards (NQA-1, 10 CFR 50 Appendix B, 10 CFR 21, ASME BPVC Section III & VIII). Familiarity with additive manufacturing, precision machining, forming, or specialty material processing. Experience conducting supplier audits, facility assessments, or first article inspections. Familiarity with quality management systems (e.g., ISO 9001, AS9100) and their role in supplier qualification. Understanding of DFARS/ITAR-relevant sourcing constraints for regulated industries. Additional Requirements: Must be willing to work extended hours and weekends as necessary to accomplish our mission. Must work 100% onsite at El Segundo HQ. Benefits and Perks Stock: Substantial incentive stock plan for all full-time employees. Medical: 100% up to base silver level plan for employee + 50% dependents, offers up to Platinum plans. One Medical: Sponsored memberships for employees and their dependents. Vision: 100% top tier plan coverage + 50% for dependents. Dental: 100% top tier plan coverage, orthodontia extra, 50% for dependents. Voluntary life, accident, hospital, critical illness, commuter and FSA/HSA are offered as employee contributed benefits. 8-weeks of paid parental leave for all parents. Additional paid pregnancy leave for CA employees. Daily catered lunch. Free snacks and drinks. Flexible PTO policy. Remote workday allocation. Company and team-bonding events, happy hours and in-person camaraderie. Beautiful El Segundo headquarters close to the Pacific Ocean.
