Principal Motion Planning Engineer

We are seeking a Principal Motion Planning Engineer to provide technical leadership for next-generation autonomous driving systems. This role will own complex planning problems from architecture and algorithm development through simulation, validation and production deployment.

Responsibilities

• Lead architecture and development of behavior planning, trajectory generation and motion optimization systems.
• Develop safe, comfortable and dynamically feasible trajectories across complex highway and urban scenarios.
• Address challenging behaviours including lane changes, merging, intersections, obstacle avoidance and emergency manoeuvres.
• Integrate perception, prediction, localization and vehicle-control interfaces into the planning stack.
• Develop planning approaches that account for uncertainty, vehicle dynamics and surrounding-agent behavior.
• Analyze real-world autonomy failures and translate findings into planning improvements.
• Build simulation and evaluation frameworks for large-scale planner validation.
• Provide technical mentorship and influence planning architecture and long-term technical strategy.

Requirements

• 6 - 10+ experience in autonomous driving, robotics or motion planning.
• Deep expertise in motion planning, behavior planning, trajectory generation and optimization.
• Strong C++ and Python skills.
• Experience with MPC, QP/NLP optimization, trajectory optimization and/or sampling-based planning.
• Strong understanding of vehicle dynamics and the perception → prediction → planning → control pipeline.
• Experience deploying planning algorithms on real autonomous vehicles.
• Learning-based planning, RL or imitation learning.
