About The Position

DiDi's autonomous driving unit was established in 2016 with the mission of developing Level 4 autonomous driving (AD) technology to make transportation safer and more efficient. 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.
We are seeking a passionate and driven intern to join our Planning team for the summer. You will contribute to enhancing the efficiency and scalability of our autonomous vehicle planning system. This role offers hands-on exposure to system architecture, motion planning algorithms, and build optimization in a high-performance production codebase.
