Job Title
Motion Planning Engineer (PhD, Intern)
Job Description
Job title: Motion Planning Engineer (PhD, Intern) Role Summary: Apply research expertise in motion planning to design and refine behavioral and trajectory algorithms for autonomous vehicles, integrating geometry-based path planning with context-aware speed control, and collaborating across perception, prediction, and control teams. Expactations: Deliver innovative planning solutions, implement and benchmark algorithms in simulation and real-world tests, debug performance issues, and contribute to research publications and technical documentation. Key Responsibilities: - Implement behavioral planning modules for lane changes, merges, yields, and multi‑agent interactions. - Design and optimize motion planning algorithms that merge geometry‑based path reasoning with speed reasoning to produce smooth, safe trajectories. - Develop core geometry and velocity planning systems that maintain feasibility, compliance, and comfort under varied driving scenarios. - Model complex driving environments and agent behaviors to build robust world representations under uncertainty. - Formulate cost functions and optimization frameworks balancing safety, comfort, and efficiency. - Analyze, test, and debug system performance using simulation and real‑world data; conduct root‑cause investigations and recommend improvements. - Collaborate with researchers and engineers in Perception, Prediction, and Control to integrate planning into a reliable autonomy stack. Required Skills: - PhD‑level research background in motion planning, robotics, or autonomous systems. - Strong knowledge of motion planning algorithms (optimization, sampling, graph/search‑based). - Experience with behavioral planning, trajectory optimization, and multi‑agent interaction modeling. - Published research in top tier conferences (RSS, ICRA, IROS, CVPR, NeurIPS, CoRL). - Hands‑on C++ and Python programming for real‑time algorithms. - Analytical problem‑solving, effective communication, and collaborative mindset. Required Education & Certifications: - PhD in Robotics, Computer Science, Electrical Engineering, or related field (or imminent completion). - Prior research or internship experience in motion planning and autonomous systems.
