What you will do

• Design, build, and maintain the integrated hardware-in-the-loop test environment, including racks, avionics, breakout hardware, load emulation, harnesses, and test equipment.
• Build simulation, data-acquisition, and control infrastructure for exercising flight software with real and representative spacecraft hardware.
• Develop automated test frameworks and CI/regression pipelines with continuous execution, pass/fail adjudication, regression detection, and failure reporting.
• Debug failures across flight software, avionics, interfaces, harnessing, timing, communications, and test infrastructure through root-cause analysis.
• Validate timing-sensitive interfaces, telemetry, system health, test coverage, anomalies, and requirements traceability, including long-duration testing.
• Lead final flight-hardware integration and testing before launch in coordination with subsystem engineers.

Requirements

• Degree in computer, electrical, aerospace, or related engineering, or equivalent hands-on experience.
