Machine Learning Engineer - Vision Foundation Models

Foster City, CA / Boston, MA / Seattle, WA / San Diego, CASoftware – Autonomy Software /Full-time /HybridThe Perception team at Zoox is responsible for how our purpose-built robotaxi understands the world, including what happens inside the cabin. In this role, you will design, train, and evaluate vision-based in-cabin perception models that understand passengers, objects, and behaviors inside the vehicle. These models support rider safety and the operations that keep each ride running smoothly.You will independently own a model area end to end, from data curation and training through evaluation and deployment under real-time and compute constraints, working closely with partners across the company. Your work has a direct impact on rider safety and experience as Zoox scales its robotaxi service.In this role, you will...Design, train, and evaluate vision models that understand passengers, objects, and behaviors inside the vehicle, across detection, pose, and action recognition.Independently own a model or feature area end to end: curate data, define labeling guidelines, train and evaluate models, and take them through deployment.Set the quality bar for the models you own, using rigorous evaluation and error analysis so they are reliable enough to support live operations.Deploy models under real-time and compute constraints shared with the rest of the onboard perception system.Partner across product, operations, safety, and vehicle software to turn requirements into model specifications, metrics, and validation plans.QualificationsMS or PhD in Computer Science, Machine Learning, Computer Vision, or a related field with 6+ years of industry experience (PhD with 3+ years).Deep expertise in computer vision and deep learning for image and video understanding: object detection, pose and action recognition, and fine-grained classification, with hands-on experience with modern architectures (convolutional and vision-transformer detectors, and self-supervised or foundation-model backbones such as DINOv3).Strong proficiency in Python and PyTorch for model design, training, and evaluation. Experience with vision-language models or foundation-model backbones, and with auto-labeling or synthetic data for long-tail and rare classes.Track record of owning the full ML lifecycle on real-world data: dataset curation and labeling guidelines, training, metric design (precision, recall, and false-positive rate at an operating point), and error analysis. Bonus QualificationsExperience with in-cabin or occupant monitoring (occupant or driver monitoring systems), ideally including multi-camera or fisheye imagery and low-light conditions.Experience deploying deep learning models to real-time, resource-constrained systems (robotics, automotive, or edge devices) with TensorRT / ONNX or similar. Proficiency in C++ for model integration.$254,000 - $305,000 a yearBase Salary RangeThere are three major components to compensation for this position: salary, Amazon Restricted Stock Units (RSUs), and Zoox Stock Appreciation Rights.
