Supply Chain Specialist, Procurement

What MatX Is Building

MatX's mission is to make the world’s best AI models run as efficiently as allowed by physics, bringing the world years ahead in AI quality and availability.

We're looking for a Procurement Specialist to build and own the procurement and spend-management backbone behind our hardware programs. As we move from design into builds, we need someone who can run the full purchase-to-pay cycle: issuing POs, tracking commitments, managing logistics, and making sure suppliers and invoices are handled cleanly, while giving Finance and leadership a clear, real-time picture of where our money is going.

You’ll sit at the intersection of Hardware, Finance, and Technical Program Management, and partner closely with Business Development and our planning team. This role starts hands-on and transactional, but grows with the company: first standing up our spend and procurement systems, then owning material planning against commitments, and ultimately helping shape how we communicate supply strategy to executives and suppliers alike.

• Own the end-to-end purchase-to-pay process using procurement tools to ensure POs are issued based on lead times, track logistics including reverse logistics
• Engaging with sourcing, engineers, suppliers, and finance partners to keep all stakeholders aligned, requirements and update are documented, obtain approval for PO
• Generate and maintain periodic reports, provide accurate supply chain data to the leadership team for strategic decision making, supplier performance and customer commitments, document changes
• Proactively identify and elevate supply chain risks to ensure timely mitigation and prevent delays to critical build schedules
• Work closely with Business Development, Finance, and Sourcing to keep procurement aligned with program schedules and budget, adapt to updates
• Maintain meticulous, audit-ready documentation within spend-management platforms to support financial transparency
