About this role
There was a time when all of America believed that the future of the physical world could be radically different. The engineers of the mid-1900s put a man on the moon in eight years, designed and built planes and submarines from scratch in under three, and conceived of building things we wouldn’t even be able to dream up today.
Today, the last of the engineers who imagined and built these systems are retiring. As they go, we lose not only the engineering knowledge gained from their decades of imagination and trial-and-error, but also the spirit that made that imagination possible.
Amca is working day-in and day-out to restore America’s ability to engineer anything that our critical systems depend on, and reinvigorate the cycle of creation that allows imagination to shape physical reality. We rapidly develop and manufacture new critical components and subsystems required to build and sustain the planes, military vehicles, and core infrastructure America needs. By restoring the capability of our antiquated supply chains, we increase the country’s capacity to imagine and realize new systems, and make a physical world that looks very different from today.
Overview:
Supply Chain Buyers own end-to-end procurement for Amca's manufacturing operations. We will hand you a set of parts, you'll be held accountable for whether they show up on time at the right price, and we'll give you the autonomy to make that happen. You'll source and fulfill the parts and materials that go into our builds, track hardware from quote through delivery, and keep the manufacturing floor stocked to support build rate. You'll also own the supply chain health of your assigned commodities and build out the supply base by vetting new suppliers in that commodity and partnering with only the best.
Responsibilities:
Procurement
Own the full procurement cycle: source, quote, negotiate, and issue POs for machined parts, hardware, raw materials, special processes, and consumables
Manage open orders end to end: track deliveries, update lead times, and expedite anything putting the build schedule at risk
- Resolve PO discrepancies across receiving, suppliers, and engineering — own each issue through to closure
- Maintain accurate ERP/MRP data: open POs, lead times, pricing, vendor records, and part statuses
Maintain visibility into build status and material readiness, and flag shortages early enough to act on
- Identify cost and lead time improvement opportunities across the supply base
Supplier Development
Identify and onboard new suppliers across machining, injection molding, PCBAs, electronics, soft goods, testing, assembly, and other processes as needed
- Vet suppliers on capability, quality systems, capacity, and certifications
Visit shops to assess them first-hand and build the relationships that get Amca's needs prioritized when it matters
Run quarterly business reviews and grow a vendor base that can scale with our manufacturing operations
Expectations:
In your first year, you own your scope outright: on-time delivery to promise, zero line-down shortages you didn't flag in advance, measurable cost and lead time reduction across your supply base, and at least five newly qualified suppliers across your commodities.
Qualifications:
1–5 years (including internships) in purchasing, procurement, materials planning, or supply chain analysis in a manufacturing environment
Demonstrated ownership of PO management and open order tracking in an ERP or MRP system
Strong organizational skills to be able to manage a large and constantly shifting queue of open orders and build priorities
Direct, proactive communicator with suppliers, engineers, and the production floor
Thrives in a fast, ambiguous environment where the plan changes
Able to travel 25%, with heavier stretches during supplier qualification campaigns
Preferred Qualifications
Comfortable working from BOMs and engineering drawings to translate requirements into procurement actions
Aerospace, defense, or precision manufacturing background
- Familiarity with supplier qualification processes and quality documentation (C of C, material certs, AS9100)
Experience sourcing across a broad range of commodities — machining, PCBAs, electronics, testing, coatings, NDT
Annual Salary Range
$80,000—$120,000 USD
