System-Level Debugging: Own triage and root-cause analysis across sensing, compute, networking, harnesses, connectors, and power, converting findings into design changes, containment actions, and documented corrective actions that measurably raise fleet reliability and uptime. Validation & Test Infrastructure: Design and build the HIL benches, breakout hardware, and instrumentation that integrate compute, sensors, and actuators, so software and autonomy teams can develop and regress against a safe, representative platform instead of competing for a vehicle.
