DoorDash completes over 2.5 billion deliveries per year and is investing heavily in the next generation of delivery automation. This role is part of a small, high-impact team building a new autonomous system from the ground up, with the potential to eventually operate at a massive global scale. We haven’t publicly announced this specific project yet. We are seeking a highly capable, driven, and passionate mechanical engineer to design and develop high performance electric motors. The primary application of these motors is unmanned aerial vehicle (UAV) propulsion. There are other important motors on our aircraft and within ground equipment that we may decide to develop in house as well. About the role... This is an exploratory product space with significant opportunity for architectural ownership. This role is on-site in San Francisco’s mission district at least 3 days per week. Availability to be onsite 5 days per week is required with flexibility to work from home as appropriate. Occasional travel to suppliers is expected. You will operate in a very fast-paced, prototype-driven environment where hands-on engineering and rapid iteration are encouraged. We provide access to a full machine shop with welding equipment, additive manufacturing tools, electrical integration tools, and significant in-house test capability to enable efficient concept-to-hardware development. This is a senior role that offers autonomy, cross-functional collaboration, mentoring, and opportunities for increasing responsibility. You're excited about this opportunity because... Collaborate closely with: Electro-mechanical design experts on winding and magnet design. Internal, domestic and foreign manufacturing partners Electrical, systems, structural, aerodynamics, reliability, and test engineers as well as industrial design to refine requirements. Design mass and volume optimized rotor and stator structures. Bearing selection and bearing system design. Electrical wiring and connector selection and integration. Motor sensor selection and integration (rotary encoders, temperature, etc.) Perform structural and thermal finite element analysis (FEA) to optimize performance and reliability. Start to finish ownership of motors from concept through production. Build prototypes, fixtures, and test hardware using CNC tools and 3D printers. Design for outdoor commercial operation including ingress protection and harsh environmental survival. We're excited about you because... Mechanical engineering bachelors degree and 3+ years of experience. Experience with dynamic mechanical systems (motors, actuators, mechanisms, etc.) Strong 3D modeling (CAD) skills for complex parts and assemblies. Self sufficient with at least basic structural and thermal simulation. Self sufficient with hands-on prototyping, metal fabrication, 3D printing. Competence with assembly and test fixture design. Familiar with electromechanical integration and wiring practices. Experience designing hardware for outdoor or harsh environments. Strong understanding of manufacturability and assembly methods. Comfortable working in an exploratory, fast-paced environment. Bonus points for experience with electric motor manufacturing processes and equipment.
