HADRIAN - MANUFACTURING THE FUTURE Hadrian is building autonomous factories that help aerospace and defense companies manufacture rockets, satellites, jets, and ships up to 10x faster and up to 2x cheaper. By combining advanced software, robotics, and full-stack manufacturing, we are reinventing how America produces its most critical parts. We’re accelerating our mission with the launch of Factory 3 in Mesa, Arizona, a 290,000-square-foot facility creating 350 new jobs. We are expanding rapidly to support thousands of future hires, launching Hadrian Maritime to expand into naval production, and introducing a Factory-as-a-Service model that delivers complete systems instead of individual parts. Hadrian is backed by leading investors including T. Rowe Price, Lux Capital, Founders Fund, and Andreessen Horowitz, our fast-growing team is united around reindustrializing American manufacturing for the 21st century and beyond. The Role The Senior Supply Chain Buyer (Direct Spend) is responsible for end-to-end procurement execution and supplier management in support of Hadrian's supply chain. This role sits at the intersection of sourcing, contract management, and supplier performance: acting as the connective tissue between our customers, internal teams, and supply base. You will own the full lifecycle from RFQ through PO execution, ensuring we hit cost, quality, and schedule targets while building the supplier relationships that sustain long-term program success. What You'll Do Your responsibilities will include, but are not limited to the following: * Lead sourcing efforts across your assigned commodity or program area, including RFQ development, supplier selection, negotiation, and PO management through acknowledgement. * Serve as the primary interface between suppliers and customers, ensuring alignment on requirements, timelines, and quality standards across the supply chain. * Own demand fulfillment accountability, with a relentless focus on quality, while optimizing for cost and schedule. * Develop and maintain strong supplier relationships, using performance data and KPIs to drive accountability, continuous improvement, and root cause resolution in partnership with Supplier Quality. * Provide tactical support on both customer and supplier contracts, ensuring commercial and technical requirements are executed and upheld. * Identify process gaps and build or improve operational workflows where they don't yet exist. * Maintain tight feedback loop with internal supplier quality to ensure issue resolution is swift and accurate. What We're Looking For * 2+ years of relevant experience in procurement or supply chain execution owning a direct commodity such as machined components, electronics, sheet metal, raw material, or PCB/PCBA. * Bachelor's degree in supply chain management, business, engineering, or related field. * Strong project management instincts: able to juggle multiple accounts and competing priorities with high attention to detail and clear, proactive communication to all stakeholders. * Comfortable navigating engineering data (drawings, GD&T, specifications) to interpret manufacturing requirements. * Proven ability to build cross-functional relationships with engineers, supply chain peers, and other internal stakeholders alike. * Experience working in fast-paced, ambiguous environments where priorities shift and speed matters. * Proficiency with ERP related systems and purchasing/planning functions. What Will Set You Apart * Experience interpreting GD&T and component profiles to determine manufacturing requirements. * Track record of successful NPI negotiations without prior purchase or sourcing data to rely on. * Supplier performance management experience influencing improvement through KPI-driven actions. * Familiarity with aerospace, defense, or other regulated manufacturing industries. * Experience with personally growing and developing a supply base.
