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., * Own the design, build, and operational execution of Hardware-in-the-Loop (HIL) testbeds and bench-level automated test setups for the Arc vehicle. * Develop and release vehicle-level avionics functional test plans, verification procedures, and automated test scripts to validate electrical power, computers, and RF subsystems. * Design and manufacture electrical Ground Support Equipment (GSE), breakout boxes, and custom test cables required for vehicle checkout. * Perform system-level electrical integration testing, signal mapping, and bus health analysis for communication networks (CAN, Ethernet, Serial, SPI, I2C). * Analyze avionics telemetry and sensor data during execution of simulated flight profiles to ensure hardware conforms to technical performance margins. * Lead the investigation and troubleshooting of electrical failures, telemetry drops, and hardware-software anomalies discovered during test campaigns. * Define environmental qualification test plans (thermal vacuum, vibration, shock, EMI/EMC) specifically tailored for avionics flight hardware. * Mentor junior test engineers, standardizing data-driven analysis techniques and automated test suite architectures.
