The Manufacturing Partner Marketplace is the operational heart of Protolabs Network. We own the full order lifecycle - matching orders to the right manufacturing partners, moving them through production and quality control, and ensuring on-time delivery.

Within this domain you'll be building systems that power the marketplace - automated auctions, order allocation, supplier tooling, production workflows, global logistics, quality control, and internal ops tools. We are looking for a pragmatic problem solver who will thrive in a dynamic environment and can take ownership of the business problem, not just the technical solution.
