Localization is at the heart of our mission to connect creators with their communities on a global scale. We're looking for a Localization Program Manager to own the operational core of our localization program — vendor coordination, content workflows, quality processes, and launch execution across 29 languages. You'll join a lean team of senior professionals who operate as strategic partners to Product and Engineering and focus on bringing global users a native experience. Strong performers can take on increasing scope over time. You can work from San Francisco, CA; Irvine, CA; Seattle, WA. You Will: Manage end-to-end localization into 29 languages, including launches that require creative asset localization, terminology building and testing Monitor continuous localization operations while identifying and implementing opportunities for improvement. Run and evolve localization quality processes: coordinate testing, build LQA workflows and propose improvements based on data. Monitor and improve translation quality output by developing and maintaining linguistic assets Influence upstream content operations for seamless, context-rich translations. Build localization metrics reports (turnaround,

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.
