- Build and enhance geometry systems for generating feasible, compliant paths
- Create velocity systems for context-aware, comfortable, and safe speed profiles
- Model driving scenarios and agent interactions to support behavioral planning
- Analyze system performance, conduct testing, and investigate root causes across various scenarios
What they're looking for
- C++ proficiency for real-time algorithm implementation
- Motion planning and trajectory optimization
- Robotics fundamentals and decision-making systems
- Control theory and optimization algorithms
- Vehicle dynamics and longitudinal/lateral control
- Machine learning and reinforcement learning
- World environment reasoning and trajectory ranking
- Python or other scripting languages for prototyping
Benefits
- Work on Level 4 autonomous driving technology
- Collaborate with Prediction, Perception, and Control teams
- Equity and bonus compensation
- Health and standard benefits package
- San Jose, CA location with potential for relocation support
