• Hands-on experience with system-level test equipment (DMMs, oscilloscopes, DAQs, signal generators, flow meters, leak detection equipment, etc.). 

• Proficient in developing test plans, requirements tracing, test scripts (Python, MATLAB, or similar), and test automation tools. 

• Strong troubleshooting skills across hardware, software, and embedded systems. 

• Solid understanding of space-relevant avionics qualification and acceptance standards (e.g., NASA-STD-8739.4, ECSS, MIL-STD-1540, MIL-STD-883, NASA GEVS, or similar). 

Preferred Qualifications: 

• Experience with space vehicle or satellite bus integration & test processes. 

• Knowledge of system safety, fault management, and redundancy in space vehicle architectures. 

• Experience with environmental and EMI/EMC testing. 

• Familiarity with configuration management, requirements management, and issue tracking tools. 

• Previous work with mission operations or on-orbit test and diagnosis is a plus.
