> Build and deploy the ML-based perception system (3D detection, BEV, tracking, sensor fusion) for L4 autonomous trucks, owning models from architecture through onboard deployment and safety validation. Requires 5+ years in ML perception/robotics, strong Python/C++/PyTorch, and classical perception fundamentals.

## Job Description

## Responsibilities
- Design, train, and deploy deep learning models for 3D object detection across LiDAR, camera, and radar sensors.
- Build multi-sensor fusion architectures that combine independent detection and classification streams.
- Characterize perception failure modes, build targeted evaluation sets, and hill-climb system-level metrics.
- Build and operate the data engine: shadow-mode comparison against production, automated data mining, and retraining loops.
- Contribute to camera- and LiDAR-based localization perception under degraded conditions.
- Take your work through the full safety validation pipeline before it operates on public roads.
- Collaborate daily with behavior/planning engineers, systems and safety engineers, and validation teams.

## Requirements
- Bachelor's or Master's degree in Computer Science, Robotics, Electrical Engineering, or a related field.
- 5+ years of professional experience in ML-based perception, computer vision, or robotics.
- Strong proficiency in Python and C++.
- Hands-on experience training and deploying deep learning models in production (e.g., PyTorch).
- Solid grounding in classical perception: multi-object tracking, state estimation, and 3D geometry.

## Nice-to-Haves
- Experience working in modern ML-based perception for autonomous systems.
- Experience with multi-sensor calibration and fusion.
- Experience optimizing models for onboard/embedded GPU inference.
- Background in safety-critical or automotive software development.
- Experience in a startup or fast-paced environment.

## Compensation and Benefits
- Base salary range: $151,000 - $255,000 USD annually.
- Total compensation package may also include equity (options and/or restricted stock units), comprehensive health, dental, vision, life and disability insurance coverage, 401k retirement benefits with employer match, learning and wellness stipends, and paid time off.
- Actual base salary influenced by experience, credentials, education, skills, interview performance, and level/scope of position.
