## About the Role

Do you have experience in Troubleshooting electrical systems?, * Bachelor's degree in Electrical Engineering, Computer Engineering, Aerospace Engineering, or equivalent technical experience.

 * Typically 5+ years of hands-on experience testing and validating high-reliability avionics, complex electrical subsystems, or embedded systems.
 * Strong proficiency in Python or equivalent programming languages for test automation, hardware scripting, and data analysis.
 * Direct experience configuring and utilizing standard laboratory diagnostic equipment (oscilloscopes, digital multimeters, spectrum analyzers, and logic analyzers).
 * Experience building or operating automated test environments, HIL test beds, or telemetry systems.
 * Deep technical understanding of analog/digital signal path debugging and serial communication protocols.
 * Excellent verbal and written communication skills., * Experience qualifying avionics hardware to military or aerospace environmental standards, including TCYC, TVAC, shock, and vibe qualification campaigns.
 * Familiarity with RF telemetry, high-voltage battery systems, and pyrotechnic trigger systems.
 * Experience with aerospace safety-critical systems or fault-tolerant hardware architectures.
 * Prior experience supporting full-vehicle integration campaigns.
 * Prior experience in a fast-paced aerospace startup or small hardware development team.

## Description

* 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.
