In this role, you will contribute to the development of our next-generation 3D occupancy and segmentation networks. You will architect and optimize high-performance deep learning models that generate dense, temporally consistent voxel representations of the driving environment. This work is critical for enabling our vehicle to navigate complex urban scenarios, handle rare obstacles, and drive safely in tight spaces by providing precise geometry and motion estimates to downstream planners.\nIn this role, you will...\nDesign and implement state-of-the-art multi-modal sensor fusion architectures (Lidar, Camera, Radar) to predict 3D occupancy, semantic segmentation, and flow .\n\nDevelop \"vision-first\" fusion strategies to enhance geometric understanding and reduce dependency on sparse sensor modalities .\n\nEngineer temporal processing modules to improve the stability and consistency of predictions over time.\n\nOptimize model architectures for real-time on-vehicle inference, balancing high-fidelity range extension with strict latency constraints .\n\nCollaborate with downstream consumers (Tracking, Prediction, Planner) to refine geometric outputs, such as contours and free-space estimations, for complex maneuvering.\n\nQualifications\nMS or PhD in Computer Science, Robotics, Machine Learning, or related field with 6+ years of industry experience.\n\nDeep expertise in 3D Computer Vision and Deep Learning, specifically with voxel-based or BEV (Bird's Eye View) architectures.\n\nStrong proficiency in Python and deep learning frameworks (PyTorch) for model training and design as well as some experience in C++ for model integration.\n\nExperience with multi-sensor fusion (Lidar, Camera, Radar) and handling temporal data sequences.\n\nExperience with occupancy networks, implicit representations (NeRF/Gaussian Splats), or scene flow estimation.\n\nBonus Qualifications\nExperience optimizing models for TensorRT/CUDA to achieve low-latency inference.\n\nFamiliarity with sparse convolutions or query-based architectures for efficient 3D processing.\n\nExperience with Vision Language Model, or multi-modal 3D foundation model, or World Model, or VLA.","description_format":"text","description_chars":2330,"description_truncated":false,"requirements":{"experience_years_min":6,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United
