Job Description

Own the technical backbone of TRISO-X's subcontract oversight. This Subcontract Technical Manager role oversees every dollar, deliverable, and day of subcontracted work for the TRISO-X fuel fabrication — ensuring suppliers deliver to nuclear-grade standards (NQA-1, 10 CFR 50 Appendix B, DOE O 414.1D) on schedule, on budget, and with the quality rigor that reactor and fuel production demands. You'll be the critical technical bridge between engineering, project controls, quality, procurement, and regulatory teams and the supply base that makes our first-of-a-kind missions possible, coordinating inputs across disciplines to ensure subcontracted scope integrates seamlessly with program objectives and contract requirements.
We need a proven subcontract technical leader who thrives in high-stakes, nuclear-regulated environments: someone who has managed multi-million-dollar subcontract portfolios under NQA-1 or equivalent QA regimes, held suppliers accountable for both technical compliance and cost/schedule performance, and built the cross-functional coordination discipline required to keep complex programs on track. You'll oversee cost, schedule, and performance across all subcontracted scope — tracking deliverables, managing vendor performance through design reviews and site inspections, identifying risks before they threaten program success, and coordinating across engineering, project controls, quality, procurement, and licensing to resolve technical issues in real time. This role demands both strategic oversight (defining subcontract strategies, evaluating make/buy decisions, participating in material review boards and NCR resolution) and hands-on technical coordination (reviewing subcontractor submittals for spec compliance, conducting constructability assessments, ensuring QA/QC adherence on-site). You'll present performance to internal and external stakeholders, drive process improvements across the subcontract lifecycle, and ensure every supplier relationship strengthens — not threatens — X-energy's nuclear safety culture and mission delivery.
