Senior Manager, Supply Chain Planning

Xometry (NASDAQ: XMTR) powers the industries of today and tomorrow by connecting the people with big ideas to the manufacturers who can bring them to life. Xometry’s digital marketplace gives manufacturers the critical resources they need to grow their business while also making it easy for buyers at Fortune 1000 companies to tap into global manufacturing capacity. As Xometry moves from transactional custom parts into recurring production programs, the planning problem changes shape. Strategic programs commit us to volumes, lead times, and capacity months ahead of demand, across a distributed network of manufacturing partners. Doing that well requires demand and supply planning capabilities that do not fully exist yet. The Senior Manager, Supply Chain Planning will build them. This role is responsible for developing the demand planning, supply planning, and analytical capabilities that underpin Xometry's strategic programs, and for turning those capabilities into decisions leadership can act on: what capacity to secure, where to place volume, what inventory to hold, and where the risk sits. Alongside the planning mandate, this role will directly program manage a set of new and emerging opportunities. These are programs without an established playbook, where the work is to structure the problem, stand up the operating approach, and prove it out before handing it to a steady-state owner. This is a build role as much as a run role. It suits someone with strong analytical fundamentals and a consulting-grade ability to structure ambiguity, who wants to own the answer through implementation rather than stop at the recommendation. This role reports to the Director, Strategic Program Enablement.
