Software Engineer – Motion & Behavioral Planning

About this role

DiDi Autonomous Driving seeks a Software Engineer to develop behavioral planning and motion planning systems for Level 4 autonomous vehicles. You'll design decision-making algorithms that enable safe, intelligent navigation by integrating high-level behavioral reasoning with trajectory optimization in complex driving environments.

What you'll do

• Design and implement behavioral planning logic for vehicle actions like lane changes, merges, and agent interactions
• Develop motion planning algorithms that optimize geometry and velocity profiles into cohesive trajectories
• Architect path generation systems for geometrically feasible and compliant routes
• Create velocity profiles that balance safety, comfort, and efficiency
• Model driving scenarios and agent interactions to support robust world modeling
• Analyze system performance, debug edge cases, and collaborate with Prediction, Perception, and Control teams

What they're looking for

• C++ (real-time algorithm implementation)
• Motion planning and trajectory optimization
• Behavioral planning for autonomous systems
• Robotics fundamentals and control theory
• Search and optimization algorithms
• Vehicle dynamics and trajectory ranking
• Machine learning and reinforcement learning (preferred)
• Automotive software development

Benefits

• Competitive base salary ($129k-$215k for Software Engineer; $149k-$247k for Sr. Software Engineer)
• Bonus and equity compensation
• Health and wellness benefits
• Work on cutting-edge Level 4 autonomous driving technology
• Collaborative team environment
• San Jose, CA location
