ABOUT THE TEAM Our Robotics team is focused on unlocking general-purpose robotics and pushing towards AGI-level intelligence in dynamic, real-world settings. Working across the entire model stack, we integrate cutting-edge hardware and software to explore a broad range of robotic form factors. We strive to seamlessly blend high-level AI capabilities with the constraints of physical systems to improve peoples’ lives. ABOUT THE ROLE We are seeking a Mechanical Design Engineer to lead the development of motor mechanical designs and prototype hardware for advanced robotic systems. You will own stator and rotor mechanical development from early concepts and detailed design through hands-on builds and prototype validation, partnering closely with electromagnetic, electrical, test, and manufacturing teams. This role focuses on the design, integration, and validation of motor components and prototype processes, including laminations, stack assemblies, bobbins, winding interfaces, and fixtures. You will help drive motor development from initial design through repeatable low-volume builds while establishing the tooling, work instructions, and validation practices needed for future robotic platforms. This role is based in San Francisco, CA, and requires in-person presence 4 days a week. IN THIS ROLE, YOU WILL - Own stator and rotor mechanical designs and released CAD and drawings, including geometry, interfaces, fits, tolerances, retention, assembly access, and mechanical validation. - Develop laminations, stack assembly methods, bobbins, and winding interfaces that control alignment, insulation, conductor placement, and end-turn packaging. - Design, fabricate, and debug fixtures for winding, stacking, assembly, alignment, and inspection. - Build and troubleshoot prototypes. Use measurements, defects, rework, and assembly effort to improve designs and processes. - Establish low-volume prototype production with equipment, build sequences, work instructions, revision control, traceability, and acceptance checks that let technicians reproduce successful builds. - Test new manufacturing methods and winding approaches, balancing performance, repeatability, and practical implementation. - Work with electromagnetic, electrical, manufacturing, and test engineers to resolve tradeoffs between motor performance, packaging, buildability, and validation. YOU MIGHT THRIVE IN THIS ROLE IF YOU - Move comfortably between CAD, the shop, measurements, and
