We are looking for a Senior Engineer to join our Calibration, Localization and Mapping (CLAM) team. Someone with deep expertise in multi-sensor calibration for autonomous systems who can ensure our trucks' cameras, lidars, radars, and IMUs are precisely characterized and fused with confidence.

In this role, you will:

• Develop and maintain intrinsic and extrinsic calibration algorithms for cameras, lidar, radar, and IMU sensors, and set the technical strategy for these systems.
• Build online/self-calibration systems that detect and correct sensor drift or misalignment over the life of the vehicle.
• Characterize sensor uncertainty and noise models to support downstream localization and perception fusion, anticipating failure modes before they arise in the field.
• Design and maintain tooling for factory calibration, field recalibration, and post-maintenance verification.
• Develop and evangelize metrics and automated checks to validate calibration quality and flag degraded sensors.
• Troubleshoot calibration issues found in the field or in simulation, driving root-cause fixes and serving as a technical escalation point for complex or ambiguous calibration problems.
• Collaborate closely with Localization, Mapping, Perception, and Hardware teams, and guide sensor selection strategy in partnership with Hardware and Sensors teams.
• Mentor other engineers and represent CLAM in cross-functional design reviews.

What you'll bring:

• Strong technical background. BS, MS, or PhD with academic or industry experience in sensor calibration, computer vision, or robotics.
• Skilled in C++ with strong software engineering fundamentals, and experience building high-reliability deployed applications. Code is your craft.
• Experience with intrinsic and extrinsic calibration techniques (e.g., camera-lidar calibration, hand-eye calibration, target-based and targetless methods).
• Experience with optimization techniques used in calibration (e.g., bundle adjustment, nonlinear least squares, factor graphs).
• Solid understanding of sensor uncertainty modeling and how calibration errors propagate into localization and perception.
• Solid understanding of metrics, data analysis, and scientific evaluation.
• A team player. You take ownership and are interested in the performance of the entire system across engineering disciplines.
• Ability to build and iterate quickly, and comfortable defining and building lasting infrastructure components from scratch.
• Hands on. Curious. Flexible. Interested in new domains to expand your horizons.
• Great communicator. Experience writing clear, concise design documentation to gather feedback across the team.
• (Staff-level candidates) Demonstrated ability to set technical direction, influence without direct authority, mentor engineers, and align multiple teams around a shared approach.

Bonus points if you have:

• Experience building automated calibration pipelines or in-field self-calibration systems.
• Hands-on experience calibrating sensors on a real vehicle fleet.
• Experience with point cloud registration or multi-modal sensor fusion.
