Responsibilities
- Develop perception systems for autonomous mining vehicles using LiDAR, millimeter-wave radar, 4D millimeter-wave radar, and camera sensors.
- Build LiDAR point-cloud algorithms for ground segmentation, clustering, obstacle extraction, and drivable-area detection.
- Develop environmental understanding and online local environment models for road boundaries, free space, occupancy, terrain traversability, and other inputs to localization, prediction, and planning.
- Develop detection algorithms for slopes, rocks, debris, vehicles, and people in mining environments.
- Develop and optimize LiDAR deep-learning detection models and design post-fusion between rule-based and model-based detection.
- Develop millimeter-wave and 4D millimeter-wave radar detection, clustering, tracking, velocity-estimation, and clutter-suppression algorithms.
- Develop multi-sensor fusion across LiDAR, 4D millimeter-wave radar, and cameras.
- Deploy perception systems, optimize performance, build data feedback loops, and analyze large-scale data to identify and resolve issues.
Requirements
- Bachelor’s degree or higher in computer science, automation, robotics, electronic information, artificial intelligence, or a related field.
- At least 3 years of experience developing perception algorithms for autonomous driving, robotics, or intelligent equipment.
- Proficiency in C++ and Python, with familiarity with Linux and ROS/ROS2.
- Strong understanding of point-cloud processing workflows including ground segmentation, clustering, object detection, and tracking, plus experience developing LiDAR rule-based detection algorithms.
- Familiarity with PointPillars, CenterPoint, PV-RCNN, Voxel RCNN, and BEVFusion, including experience with post-fusion and reliable perception architecture design.
- Knowledge of traditional and 4D millimeter-wave radar, with experience in millimeter-wave point-cloud clustering, tracking, velocity estimation, and clutter filtering.
- Understanding of autonomous-driving perception-system architecture and data-flow design, with large-scale data analysis and issue-localization skills.
- Preferred qualifications include 4D millimeter-wave radar detection, radar-LiDAR fusion, CUDA, TensorRT deployment optimization, production autonomous-driving projects, mining or other closed-site autonomous-driving experience, SOTIF, multi-sensor fusion, high-definition or lightweight-map systems, free-space or occupancy modeling, and real-time perception-to-map consistency checking.
