Software Engineer - Motion Planning (Fallback Stack)

Job summary

Responsibilities

As a Motion Planning Engineer on the Fallback Stack team, you will design and ship deterministic, safety-critical planning systems that ensure autonomous vehicles behave safely when autonomy degrades or operates under uncertainty.

• Design and implement classical or ML motion planners for fallback and minimal-risk maneuvers
• Build planners that operate reliably under degraded perception, partial observability, and system faults
• Use large-scale simulation and real-world data to evaluate planner behavior and guide parameter tuning
• Collaborate closely with behavior prediction, perception, controls, safety, and remote assistance teams
• Contribute to a reusable fallback platform used across trucking and other autonomy programs

What they're looking for

• 4+ years of experience in motion planning for autonomous vehicles or robotics
• Strong foundation in robotic motion planning algorithms and trajectory generation (optimization-, search-, or rule-based)
• Experience building deterministic, safety-critical planning systems
• A data-driven mindset for large-scale evaluation, debugging, and tuning of planning behavior
• Proficiency in C++ and experience working in real-time systems

Tech stack

• C++
