Avionics Test Engineer, Hardware

Apex Space  · Los Angeles  · May 13, 2026

Spacecraft represent the most pressing unmet need across the entire aerospace industry. As more launch vehicles come online and the cost to orbit decreases, more companies launching payloads to space continue to emerge. For the first time in history, this influx of payload companies combined with reduced launch costs has resulted in a massive increase in need for commercial spacecraft platforms, known as satellite buses. These buses hold the payloads of our customers and are flown on launch vehicles. Apex manufactures these satellite buses at scale using a combination of software, vertical integration, and hardware that is designed for manufacturing. Our spacecraft enable the future of society: ranging from earth observation to communications and more. We’re looking for a Hardware Avionics Test Engineer to join our growing Test team. In this role, you’ll focus on hardware integration and testing, system-level and component-level test rack planning and buildup, avionics validation, and automated spacecraft test execution. You’ll work closely with electrical, mechanical, RF, and systems engineers to build and operate integrated spacecraft test environments, execute qualification campaigns, and troubleshoot flight hardware throughout development and integration. This role is highly hands-on and ideal for engineers who enjoy working directly with hardware, integration setups, and environmental testing.
