This includes, but is not limited to, advanced search-based and sophisticated geometry-based methods, as well as decision-making under uncertainty with a strong emphasis on probabilistic approaches
• Lead cross-functional projects to define new or upgrade existing interfaces to solve problems
• Monitor overall system performance to identify areas for improvement and develop technical strategies to address deficiencies
• Guide cross-functional project teams to provide comprehensive solutions and demonstrate the ability to think beyond the confines of the planning system
• Architect and integrate complex combinations of motion planning and prediction algorithms, driving their evaluation and refinement for real-world deployment
• Design and build a robust, scalable, and high-performance codebase that facilitates rapid exploration, prototyping, and rigorous evaluation of innovative motion planning approaches and algorithms
• Drive technical collaboration and interface seamlessly with perception and prediction components upstream and trajectory optimization, tracking and control components downstream, ensuring end-to-end system performance
• Leverage your deep software development and research expertise to teach others better software practices and principles, fostering a culture of technical excellence
• Guide and mentor junior and senior team members, cultivating a culture of product-focused engineering, rigorous research, and advanced development

Skills

• PhD preferred in Robotics, Computer Science, Computer Engineering, Mechanical Engineering, or a related field; or a Master's degree with 7+ years of experience in the robotics (preferably AV industry)
• 10+ years of research experience in robotics / motion planning, with a proven track record of contributing to state-of-the-art solutions and leading significant projects
• 5+ years of C++ software development, with an emphasis on developing high-performance and reliable systems
• Past experience owning and leading technical development on complex features from problem formulation through research, implementation, and deployment in a production environment, demonstrating significant impact
• Thirst for knowledge, continuous innovation, and a drive to push the boundaries of autonomous driving technology, acting as a technical thought leader
• Experience with probabilistic models, including but not limited to Gaussian mixture models, Hidden Markov Models, and Particle Filters
• Experience with machine learning techniques (such as Bayesian modeling and inference techniques) for decision making under uncertainty
• Experience with the Bazel build framework
