The Senior Planner Engineer role at DoorDash Labs focuses on developing advanced motion planning and trajectory optimization algorithms for autonomous delivery systems. The team is composed of experienced professionals dedicated to enhancing last-mile logistics through innovative automation and robotics solutions. The ideal candidate will have a strong background in building production-level autonomy systems and will play a crucial role in addressing complex challenges in dynamic environments. This position offers the opportunity to contribute to the development of technologies that improve efficiency for Dashers, merchants, and consumers.

• You have a BS/MS/PhD in CS, EE, Robotics, or a related technical field, or equivalent practical experience.
• You have strong C++ software engineering experience building robust, production-quality systems.
• You have experience developing or deploying motion planning, trajectory optimization, robotics, or real-time decision-making systems.
• You are comfortable working with data-driven evaluation, simulation, and performance metrics to guide engineering decisions.

• Design and ship real-time behavior and motion planning features for complex urban and suburban driving scenarios.
• Lead automation of root-cause analysis and systematically eliminate planner-related disengagements and long-tail failures.
• Build scalable evaluation, simulation, and validation frameworks to ensure safe rollout to new geo-fenced regions.
• Collaborate cross-functionally with perception, prediction, controls, and platform teams to deliver end-to-end autonomy improvements.
• Contribute to architecture decisions that improve planner robustness, generalization, and computational efficiency.
