Job Summary
Principal Software Engineer leading the embedded partner integration for Xometry's AI-native marketplace, architecting native embedding of DFM and IQE into enterprise CAD/PLM environments. You will enable a "science fiction speed" workflow where designers receive real-time manufacturability and pricing feedback inside their primary design tools, by integrating core AI engines with partner applications. The role requires leading discovery and architectural design, setting engineering standards for 3D geometry data handling, and delivering scalable, secure microservices with sub-second latency. You will mentor staff and senior engineers, collaborate with Data Science to advance AI tooling within architecture and development workflows, and drive cross-team roadmaps to move from lightweight HTML snippets to deep, native integrations. Collaboration with partner engineering teams to ensure a unified digital thread, and ownership of reliability, security, and monitoring of the integration lifecycle. A strong background in Python, React/TypeScript, AWS, and enterprise software integrations, CAD/PLM domain experience, and familiarity with 3D geometry workflows are highly desired.
