Principal Engineer – Vanguard Team

Mission Summary

We are looking for a principal engineer to develop and deliver new algorithms and models for motion planning, trajectory generation, and controls to advance the capabilities of our autonomous vehicles, pushing the capabilities and reliability of the system to the next level.

• Research & Development: Lead the research, design, and development of algorithms and ML models that enhance vehicle decision‑making, expand ODDs, and ensure robustness against long‑tail events and subsystem failures.
• System Co-Design: Collaborate with cross‑functional engineering teams (Perception, Prediction, Hardware, Infrastructure, etc) to architect a holistic system that maximizes safety and performance at scale.
• Simulation & Validation: Architect dynamic simulation scenarios to validate expanded ODDs, ensuring rigorous testing of the system’s “edge case” limits.
• Documentation & Clarity: Maintain a high bar for technical excellence by clearly documenting research findings, system architectures, and validation results to ensure organizational alignment and safety traceability.
• Mentorship: Act as a technical catalyst by mentoring junior engineers in software craftsmanship, algorithmic rigor, and systems thinking.

• Expert in robotics decision making, motion planning, and controls algorithms and ML models
• Experience designing, developing, and delivering complex robotic or automation systems
• Experience with robotics systems and the ability to root cause problems
• Experience writing software for safety critical embedded systems utilizing C, Rust, or similar
• Experience developing analytics using Python, or similar
• Experience with testing, verification, and validation of systems with functional safety requirements
• Experience with simulation systems for robotics and/or autonomous vehicles
• Experience using Linux operating systems, and ability to work in terminals/shells to perform troubleshooting, system performance monitoring, and kernel/journal log debugging
• Experience profiling CPU, GPU, Disk, and Network usage

• Experience with perception or prediction algorithms and models
• Experience with open-source robotics middleware (ROS, DDS)
