In August 2019, the unit became an independent company, DiDi Autonomous Driving, dedicated to advanced AD R&D, product application, and business expansion. We believe integrating AD technology into a shared-mobility fleet will generate immense social value. By leveraging DiDi's specialized technology, operational expertise, and integrated ecosystem, we are positioned to build and operate a highly efficient, user-oriented autonomous fleet. ## About The Role We are seeking a motivated PhD graduate with a strong research background in motion planning, robotics, or autonomous systems. In this role, you will apply your expertise in algorithm design and system integration to help develop next-generation planning capabilities for autonomous vehicles. ## Responsibilities - Implement novel solutions for Behavioral Planning, enabling high-level decision-making for lane changes, merges, yields, and multi-agent interactions. - Design and optimize motion planning algorithms that integrate geometry-based path reasoning and context-aware speed reasoning into smooth, safe trajectories. - Develop and improve core geometry and velocity planning systems to ensure feasibility, compliance, and comfort across diverse driving scenarios. - Model complex driving environments and agent behaviors to create a robust world representation for planning under uncertainty. - Formulate cost functions and optimization frameworks that balance safety, comfort, and efficiency in trajectory selection. - Analyze, test, and debug system performance through simulation and real-world data, conducting root-cause investigations and proposing enhancements. - Collaborate with researchers and engineers across Perception, Prediction, and Control to ensure an integrated, reliable autonomy stack. ## Qualifications - Recently completed or soon-to-complete PhD in Robotics, Computer Science, Electrical Engineering, or a related field. - Research or Internship experience in one or more of the following: - Motion planning algorithms (optimization, sampling, graph/search-based methods) - Behavioral planning and decision-making under uncertainty - Trajectory optimization and control - Multi-agent interaction modeling - Proven research ability demonstrated by publications in top-tier conferences (e.g., RSS, ICRA, IROS, CVPR, NeurIPS, CoRL). - Hands-on experience in C++ for implementing complex, real-time algorithms. - Excellent analytical and communication skills, with a collaborative mindset. - For Internship Applicants: This role offers a clear pathway, with top-performing interns receiving the opportunity to convert to a full-time engineer upon successful completion of the program. The hourly rate for the Intern position in the selected city is $46. Interns will also be eligible for Intern benefits. Applications are accepted on an ongoing basis.
