Responsibilities
Design and implement the core Behavioral Planning logic that determines the vehicle's high-level actions (e.g., lane changes, merges, yields, and interactions with other agents)
Develop and optimize the motion planning algorithms that execute behavioral decisions, integrating Geometry Reasoning (path) and Speed Reasoning (velocity) into a cohesive trajectory
Architect and enhance the geometry system for generating geometrically feasible and compliant paths
Architect and refine the velocity system for generating context-aware, comfortable, and safe velocity profiles
Model complex driving scenarios and agent interactions to create a robust world model for the behavioral planner
Design different costs for trajectory ranking to trade off ETAs, comfort and safety of the vehicle behaviors
Conduct in-depth analysis, testing, and debugging of the system's performance in various scenarios, leading root cause investigations
Collaborate with Prediction, Perception, and Control teams to ensure a seamless flow from environmental understanding to physical vehicle motion
Qualification
Required
B.S./M.S. in Computer Science, Robotics, or a related field
Experience in autonomous systems, robotics, or automotive software development
Strong proficiency in C++ and Python for implementing complex, real-time algorithms
Solid understanding of robotics fundamentals, including decision-making, motion planning, control theory, trajectory ranking, search and optimization algorithms etc
Related experience in one or more of the following: behavioral planning, motion planning, behavior and world environment reasoning, trajectory ranking and cost design
