The engineer will plan and execute closed-course regression, feature, behavior, calibration, and other structured testing; coordinate limited operations personnel supporting the work; and ensure the vehicles, test setup, track activities, data, and results are ready to support engineering and program decisions. Perform or coordinate daily vehicle checkouts, pre-drive readiness checks, post-drive inspections, charging or fueling coordination, sensor and camera cleanliness checks, hard-drive or data-media handling, and other activities required to keep vehicles test-ready.
