Hadrian - Manufacturing the Future

Hadrian is building autonomous factories to reindustrialize America. By combining AI, advanced software, robotics, and full-stack manufacturing, we help aerospace and defense companies build rockets, satellites, aircraft, ships, and other mission-critical systems up to 10x faster and at significantly lower cost.

Following our $1.37B Series D at a $7.87B valuation, Hadrian is rapidly expanding our manufacturing footprint, launching new capabilities across welding, casting, forging, electronics, additive manufacturing, and more, while scaling our Factory-as-a-Service platform to transform how critical products are built.

Backed by leading investors including JPMorgan Chase, Valor Equity Partners, Andreessen Horowitz, Founders Fund, 137 Ventures, Lux Capital, T. Rowe Price, and Morgan Stanley, we're building the future of American manufacturing-and looking for exceptional people to help make it happen.

If you're ready to take on the most challenging and rewarding work of your career while helping create American manufacturing jobs for generations to come, you're exactly who we're looking for.

The Role

The Buyer, Subcontracts is responsible for end-to-end procurement execution and supplier management in support of Subcontract Supply Chain (externally manufactured). This role sits at the intersection of sourcing and requisition, 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 subsect of sourcing efforts for the subcontracting supply chain division, 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 through subcontract requirements, 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, subcontracting, or supply chain execution, ideally in a hardware or manufacturing environment.
• Bachelor's degree in supply chain management, business, engineering, or related field.
• Experience sourcing machined components, with working familiarity of machine shop operations, processes, and quality methods (e.g. multi-axis machining, OSP, CMM).
• 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 subcontracting in aerospace,…
