- Implement GNSS integrity, jamming, and spoofing monitoring for degraded or denied GNSS conditions.
- Capture vehicle data, run deterministic replays and regression metrics, inject faults, and report results against pass/fail tolerances.
- Support sensor calibration, field testing, sensor characterization, and diagnosis of navigation issues from vehicle logs.
- Build health-status, warning, and output interfaces used by fault-management and safety functions.
- Collaborate with autonomy, safety, perception, and vehicle-integration engineers and participate in code reviews.
Requirements
