GITAI builds space and defense hardware through deep vertical integration. We design, prototype, test, and manufacture as much as possible in-house, and rely on suppliers where they can help us move faster. Your job is to make that supply chain work. You will work directly with engineers and program teams to source parts, materials, manufacturing services, and specialized hardware needed for fast-moving development and defense programs. You will own the day-to-day procurement execution from RFQ through delivery. This is a hands-on role. You will find suppliers, get quotes, negotiate terms, place orders, push on lead times, resolve commercial issues, and make sure critical hardware arrives when the team needs it. You will often be negotiating without the purchasing power of a large aerospace prime. Good judgment, persistence, speed, and supplier relationships matter.
