Avionics Test Engineer

Advanced Reentry Technologies

**Who We Are:
**

Inversion is an aerospace and defense company pioneering advanced reentry technology to enable next-generation capabilities from space. By combining high-performance materials, precision aerodynamics, and mission-driven autonomy, Inversion is transforming reentry into an operational capability for an entirely new class of missions.

The company’s highly maneuverable reentry spacecraft, Arc, is designed for rapid global cargo delivery, hypersonic testing, and other national security missions that require precise, controlled flight through the atmosphere. Arc creates an entirely new transportation domain, unlocking unprecedented speed and global reach.

Headquartered in Los Angeles, Inversion designs, manufactures, and integrates its spacecraft under one roof, enabling the company to move rapidly from concept to flight. The company is backed by leading investors including Y Combinator, Spark Capital, and Lockheed Martin Ventures, with customers across the U.S. government and commercial space industry.

Position Overview:

As a Senior Avionics Test Engineer at Inversion 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. 

Key Responsibilities: 

• 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.
