As a Senior Avionics Test Engineer at Inversion, you will report directly to the Manager, of Arc Vehicle Avionics. In this role, you will own the electrical validation, functional testing, and environmental verification of the entire Arc avionics suite. You will bridge the gap between design and flight readiness, developing bench tests, configuring complex Hardware-in-the-Loop (HIL) environments, and design-to-build electrical ground support equipment (GSE). Operating with high autonomy, you will define verification methodologies, lead debug efforts for hardware-to-software interfaces, and ensure the vehicle electronics function flawlessly under simulated flight conditions.
