Role Overview We are seeking a Staff Simulation Engineer to build an end-to-end aerial autonomy simulation stack at DoorDash Labs. This is a highly technical, hands-on leadership role focused on defining and implementing the simulation architecture that underpins autonomy development, validation, CI/CD testing, and pilot training. You will operate as the technical authority for simulation: owning core architecture decisions, developing key components yourself, and setting engineering standards. You will build and mentor a small, high-caliber simulation team while remaining deeply involved in implementation and system design. This role is ideal for someone who has built simulation systems from first principles, understands simulator internals deeply, and is excited to create a world-class platform from scratch. Key Responsibilities Architect and implement an end-to-end simulation stack for aerial autonomy at DoorDash Labs.. Develop high-fidelity simulation capabilities, including: Flight dynamics modeling Contact modeling and constraint handling Sensor and perception simulation Autonomy software-in-the-loop (SITL) integration Design and implement scalable simulation infrastructure to support: Regression testing in CI/CD pipelines Continuous validation of flight autonomy and autopilot software stack Mission-level testing and scenario generation Build cloud-deployed simulation systems to enable large-scale parallel testing and pilot training. Partner closely with autonomy, controls, and aircraft teams to ensure simulation fidelity and validation alignment. Establish technical direction, architecture standards, and performance benchmarks for simulation. Mentor and grow a small team of simulation engineers while remaining deeply hands-on. Required Qualifications Master’s or PhD in Computer Science, Electrical Engineering, Mechanical Engineering, Robotics, Aerospace Engineering, or a related field. 10+ years of experience in robotics or physics-based simulation.

About the Team DoorDash for Business is how companies feed their people. We build the products that let a company run a recurring team lunch, give every employee a meal budget, cater an event or meeting and manage all of it through a single corporate account - across every brand and every market DoorDash operates in. About the Role We're looking for an Engineering Manager to lead a team in DoorDash for Business. 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
