About the role

Role focused on designing and optimizing multi-modal 3D perception models for autonomous driving, including 3D occupancy, semantic segmentation, and flow using Lidar, Radar, and Camera data. Hybrid on-site/remote in Foster City, CA.

Responsibilities

  • Design and implement state-of-the-art multi-modal sensor fusion architectures (Lidar, Camera, Radar) to predict 3D occupancy, semantic segmentation, and flow
  • Develop "vision-first" fusion strategies to enhance geometric understanding and reduce dependency on sparse sensor modalities
  • Engineer temporal processing modules to improve the stability and consistency of predictions over time
  • Optimize model architectures for real-time on-vehicle inference, balancing high-fidelity range extension with strict latency constraints
  • Collaborate with downstream consumers (Tracking, Prediction, Planner) to refine geometric outputs, such as contours and free-space estimations, for complex maneuvering

Qualifications

  • MS or PhD in Computer Science, Robotics, Machine Learning, or related field with 6+ years of industry experience
  • Deep expertise in 3D Computer Vision and Deep Learning, specifically with voxel-based or BEV (Bird's Eye View) architectures
  • Strong proficiency in Python and deep learning frameworks (PyTorch) for model training and design as well as some experience in C++ for model integration
  • Experience with multi-sensor fusion (Lidar, Camera, Radar) and handling temporal data sequences
  • Experience with occupancy networks, implicit representations (NeRF/Gaussian Splats), or scene flow estimation
