About the role
<div class="content-intro"><p><span style="font-size: 10pt; font-family: arial, helvetica, sans-serif;">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.</span></p></div><p style="color: rgb(81, 83, 87); font-family: Lato; font-size: 16px; font-style: normal; font-weight: 400; letter-spacing: normal; text-align: start; white-space: normal; word-spacing: 0px;"><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt; color: rgb(0, 0, 0);">Xometry is seeking a <strong>Principal Computational Engineer</strong> to set the multi-year technical direction for our 3D geometry and Design for Manufacturability (DFM) platform. You will be the senior individual contributor in this domain, owning the architecture that turns every customer-uploaded CAD model into a manufacturable, priced, and routed part across CNC, sheet metal,&nbsp;additive, injection molding, casting, and finishing processes. This role also serves as the technical architect for one of Xometry's highest-leverage strategic&nbsp;initiatives: the embedded DFM AI + IQE integration with our partner. You will lead the integration of Xometry's proprietary computational geometry and AI directly into the partner's industrial software ecosystem — including Solid Edge, NX, Designcenter, and Teamcenter — integrated within the native DesignCenter environment to deliver real-time manufacturability feedback and pricing insights. The goal is a "science fiction speed" design-to-source digital thread from ideation to physical parts, with no export, no round-trip, and no translation loss. This is a hands-on role. You will write production C++ and Python that ships to millions of&nbsp;quotes per year, define the kernel and toolchain strategy, publish or patent novel methods where they create durable advantage, and raise the technical bar of the team through mentorship, design review, and hiring. The role requires demonstrated mastery of computational geometry, geometric modeling kernels, and the messy reality of consuming arbitrary customer CAD — STEP, IGES, X_T, JT, SLDPRT, CATPart, and DXF — at scale.</span></p> <p style="color: rgb(81, 83, 87); font-family: Lato; font-size: 16px; font-style: normal; font-weight: 400; letter-spacing: normal; text-align: start; white-space: normal; word-spacing: 0px;"><span style="font-size: 10pt; color: rgb(0, 0, 0);"><strong><span style="font-family: arial, helvetica, sans-serif;">Responsibilities </span></strong></span></p> <
