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 About the Role As a Senior Mechanical Design Engineer

• Closures , you will own the architecture, design, and execution of closure systems for DoorDash's next-generation autonomous delivery vehicle.

This role sits at the intersection of mechanical engineering, vehicle integration, and product reliability, delivering robust access systems that operate safely and reliably through millions of delivery cycles in demanding real-world environments. You'll partner with industrial design, vehicle architecture, systems engineering, manufacturing, reliability, and operations teams to create closure systems that delight customers while meeting the rigorous durability, cost, and manufacturability requirements of a commercial autonomous fleet. You're excited about this opportunity because you will… Contribute materially to the form and function of a high profile delivery robot— your work will be on display for all to see and interact with You want to build products that millions of people interact with—not just drive. Every engineering decision directly impacts the customer experience. You're energized by solving first-of-their-kind engineering problems at the intersection of robotics, automotive engineering, and logistics. You enjoy working on products that move quickly from concept to real-world deployment, where engineering decisions immediately translate into operational impact. You believe autonomous delivery has the potential to fundamentally reshape local commerce by making deliveries safer, more sustainable, and more affordable. You're excited to join a highly collaborative team where mechanical engineering plays a central role in defining the future of autonomous last-mile delivery. We're excited about you because… Bachelor's or Master's degree in Mechanical Engineering or a related field. You have 6+ years of experience designing automotive body, closure, or mechanism systems, taking products from concept through production. Experience with commercial vehicles, autonomous vehicles, robotics, or high-duty-cycle products is a strong plus. You possess deep expertise in closure mechanisms including hinges, latches, actuators, linkages, counterbalance systems, and environmental sealing. You understand how to design for high-volume manufacturing using processes such as sheet metal stamping, castings, injection molding, extrusions, and welded assemblies. You have extensive CAD experience (NX (preferred), SolidWorks, CATIA) and are comfortable designing complex assemblies with robust parametric models. You are skilled at tolerance analysis, stack-up management, GD&T, and designing robust interfaces between mechanical systems. You have a strong understanding of structural design, fatigue, durability, corrosion prevention, and environmental sealing for outdoor products. You use engineering fundamentals and data to make decisions and are comfortable leveraging simulation tools (FEA, kinematic analysis, MATLAB, Python, or similar) to validate concepts. You have demonstrated success leading cross-functional technical discussions and influencing engineering decisions across multiple disciplines. You are equally comfortable reviewing CAD in a design review, troubleshooting hardware on the prototype floor, or working with manufacturing engineers to improve assembly quality.
