About the Team Design Program Managers make DoorDash's Design Studio run better. As owner of the Logistics pillar within Design Operations, you're accountable for one of our most important operating outcomes: maximizing the bandwidth of the team. About the Role You'll find where ICs and managers lose time, fragmented workflows, manual processes, meeting overload, unclear rhythms, and you'll define and build the tools and systems that fix it. That might mean shipping a new internal tool, automating a recurring workflow, redesigning how scheduling or reviews work, or establishing a better operating cadence. You own the full loop: diagnose the problem, design the system, build the tool, measure whether it worked. You're excited about this opportunity because you will… Own the Logistics outcome, maximize the bandwidth of the team. ICs and managers have more usable time. Meeting load decreases. The team can focus on high-value work. Identify the biggest sources of operational drag across the Studio and turn them into a prioritized roadmap of tools and process fixes. Define and build the tools, automations, and workflows that reduce manual coordination, including for scheduling, budgets, vendor management, and event logistics. Redesign how the Studio operates: reviews, planning cadences, rhythms for both ICs and managers, information flows, whatever determines how fast teams can move. Measure whether your systems work, usable time for ICs and managers, meeting load, adoption, hours of manual work eliminated, and iterate. Turn recurring requests into scalable solutions. The second time a problem shows up, build the thing that stops a third. Own scheduling, budget, vendor, and logistics programs as a builder, not a permanent executor, your job is to make them need less manual effort every quarter. Partner with (and, as scope grows, help develop) other DPMs on the Logistics pod. We're excited about you because you have… 5+ years in operations, program management, or bu

Our domain runs from the moment an order is placed to everything a company needs to administer it: high-complexity ordering for catering, recurring team meals, and group orders; the admin portal, identity, and member management that companies run their account on; budgets and policy enforcement; and the expense and travel integrations that connect us to our customers' finance systems. You'll own a pod of 8-10 engineers with a critical charter inside that domain, real revenue attached to it, and close partnership with Product, Design, and Sales Strategy & Operations. You must be located in the Seattle, San Francisco, Sunnyvale, or New York Metro Area for this hybrid position. You're excited about this opportunity because you will… Own a business-critical charter end to end - set technical direction, define the roadmap with your PM and Business counterparts, and be accountable for what ships and how well it runs. Build and grow a team - Hire, level up, and retain engineers; set the bar for what good looks like on your pod; give people work that stretches them. Work on a genuinely global product - Your charter serves the US alongside EMEA, LATAM, and APAC, with partner pods in India, Helsinki, and Brazil. You'll help decide what's built once globally versus what needs regional variation and build the partnerships across time zones to make that stick Take on real architectural weight - Consolidating onto one global stack means untangling parallel implementations, drawing clean service-ownership lines, and making migration calls with production tr
