Prototyping Engineer - CNC Machinist

Meta Reality Labs is connecting the world by building products and hardware devices. Many of these products are custom designed for unique requirements and integrate advanced technologies. We are seeking a Computer Numerical Control (CNC) machinist and prototyping leader to join our mechanical prototyping facility, drive process improvements and contribute to the development of next-generation hardware products. In this role, you will lead the programming and machining of complex multi-setup parts and assemblies, coordinate closely across engineering teams to debug designs, develop advanced fixtures and workholding, and drive precise assembly work. As a technical leader, you will lead operational improvements and process development across the shop, leveraging AI tools to identify opportunities for automation, efficiency, and workflow optimization. Working across a wide variety of materials—from specialized plastics to hard metals—you will tackle complex challenges to continuously elevate team standards and impact. Our prototyping facility features advanced 5-axis and 3-axis CNC machine tools, laser cutting, 5-axis waterjet cutting, and manual machining equipment. You will own the safe setup, operation, and maintenance of this gear, including tooling and fixture specification and procurement. You will serve as a key partner and cross-functional coordinator with mechanical engineering and industrial design teams to solve complex design and manufacturing challenges. We are looking for a leader excited to establish the fastest, efficient paths from CAD models to finished parts through AI-driven automation, robust process design, and team mentorship.
