Senior Manufacturing Engineer - DoorDash Air

DoorDash • San Francisco, CA

4d • Onsite

About The Position

The DoorDash Air team is bringing drone delivery to reality. To make this happen, we’re building a strong electrical team to design high reliability, high power density converters, and fault-tolerant controls electronics. Come join us to build a new class of aircrafts and deploy at scale. DoorDash Labs, established in 2018, serves as the innovation hub for DoorDash, focusing on developing automation and robotics solutions to enhance last-mile logistics. The team's mission is to create technologies that support and augment human networks, aiming to improve efficiency for Dashers, merchants, and consumers alike. We’re ruthlessly focused on business impact. We are a highly senior team composed of former pioneers from a variety of different robotics industries. As of 2025, DoorDash has completed 10B lifetime deliveries. We’re focused on how to do the next 10B even better. We're hiring a Manufacturing Engineer to help build the process and tooling behind how our autonomous food delivery platform gets made. You'll work hands-on to bring up our first high-volume drone assembly line—applying DFA and PFMEA to new designs, building out layout and workstations, and specifying the tooling and fixtures that turn a prototype into a repeatable build. You'll spend your time on the shop floor and with suppliers and contract manufacturers, solving the real problems that come up when a line moves from prototype to production: fit and tolerance issues, process failures, tooling gaps, throughput bottlenecks. This is for someone who wants to be in the weeds of execution, who thrives in a fast-moving startup environment, and gets energy from solving hard, hands-on manufacturing problems. You'll get in at the ground floor with the chance to shape how the next generation of food delivery vehicles gets built.

Requirements

• Bachelor's in Mechanical Engineering, Industrial Engineering, or a related engineering field
• 5+ years of manufacturing/mechanical engineering experience, ideally in high-volume electromechanical, aerospace, robotics, or consumer hardware production
• Hands-on experience applying Design for Assembly (DFA) / Design for Manufacturability (DFM) principles
• Experience authoring and driving Process FMEA (PFMEA) for new product introduction and ongoing production
• Experience with factory/line layout design, 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 — building process and infrastructure from scratch
• Strong cross-functional collaboration across engineering, supply chain, and production

Nice To Haves

• Familiarity with aerospace structures and electronic systems integration (composites, electro-mechanical sub-assemblies, PCBAs)
• Able to travel up to 20% of the time to support CM and supplier evaluations/support

Responsibilities

• Be our first manufacturing engineer for DoorDash Air's first 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 make sure new drone platforms are optimized for manufacturability, cost, and quality before they hit the line
• Own Process FMEA (PFMEA) development, proactively identifying and mitigating failure modes in assembly, test, and inspection before they hit yield or reliability
• Design and iterate on factory/line layout, workstations, and material flow to support a scalable, efficient production system
• Specify, source and/or design, and qualify assembly tooling, fixtures, and jigs, working directly with equipment vendors
• Partner cross-functionally with design, supply chain, internal production, and CMs to troubleshoot build issues and drive continuous improvement
• Create the manufacturing processes, Manufacturing Bill of Materials (MBOM), work instructions, and standards that scale as DoorDash Air ramps production volume

Benefits

• 401(k) plan with employer matching
• 16 weeks of paid parental leave
• Wellness benefits
• Commuter benefits match
• Paid time off
• Paid sick leave
• Medical, dental, and vision benefits
• 11 paid holidays
• Disability and basic life insurance
• Family-forming assistance
• Mental health program
