The Manufacturing Engineer role at DoorDash Air focuses on building the process and tooling for the autonomous food delivery platform's first high-volume drone assembly line. The engineer will work hands-on to transition from prototype to production, addressing real-world manufacturing challenges. This position is part of a senior team dedicated to innovating drone delivery technology. The ideal candidate will thrive in a fast-paced startup environment and be passionate about solving complex manufacturing problems.

• Bachelor's degree in Mechanical Engineering, Industrial Engineering, or a related engineering field
• 5+ years of manufacturing or mechanical engineering experience in high-volume electromechanical, aerospace, robotics, or consumer hardware production
• Hands-on experience applying Design for Assembly (DFA) and Design for Manufacturability (DFM) principles
• Experience authoring and driving Process FMEA (PFMEA) for new product introduction and ongoing production
• Experience with factory or line layout design and optimizing workstations for throughput, ergonomics, and quality
• Experience specifying, designing, and/or sourcing assembly tooling, fixtures, and jigs
• Comfortable operating in a fast-paced, ambiguous environment and building processes from scratch
• Strong cross-functional collaboration skills across engineering, supply chain, and production
• Familiarity with aerospace structures and electronic systems integration
• Ability to travel up to 20% of the time to support contract manufacturer and supplier evaluations

• Be the first manufacturing engineer for DoorDash Air's mass-production drone assembly line from pilot build through full-rate production
• Apply Design for Assembly (DFA) principles in partnership with hardware and electrical engineering to optimize new drone platforms for manufacturability, cost, and quality
• Own Process FMEA (PFMEA) development to proactively identify and mitigate failure modes in assembly, test, and inspection
• Design and iterate on factory and line layout, workstations, and material flow to support a scalable and efficient production system
• Specify, source, and qualify assembly tooling, fixtures, and jigs while working directly with equipment vendors
• Partner cross-functionally with design, supply chain, internal production, and contract manufacturers to troubleshoot build issues and drive continuous improvement
• Create manufacturing processes, Manufacturing Bill of Materials (MBOM), work instructions, and standards that scale as production volume ramps up
