Responsibilities
Design and build electronic test hardware—including HIL benches, flat-sat interfaces, and custom test fixtures to verify and validate spacecraft avionics and subsystems
Develop and maintain automated test control software using Python (primary), LabVIEW, or MATLAB to streamline execution and data collection
Troubleshoot and diagnose hardware issues across analog, digital, and RF interfaces; perform root-cause analysis using oscilloscopes, logic analyzers, and network analyzers
Execute “test-like-you-fly” scenarios to validate FSW–hardware interactions, timing, and fault management
Support prototype, qualification, and flight test configurations, optimizing setups for repeatability and robustness
Participate in on-orbit checkout and RF subsystem validation, including link verification and payload throughput analysis
Capture, analyze, and document test data to assess performance trends and improve test coverage
Manage test scripts, configurations, and documentation using version control systems (e.g., Git)
Collaborate closely with design, software, and AI&T teams to translate system requirements into detailed hardware-level verification procedures
Drive continuous improvement in test hardware design, automation, and system reliability across multiple spacecraft builds
Qualification
Required
5+ years of experience in spacecraft, aerospace, or high-reliability electronic hardware testing and integration
Proven experience designing, building, and troubleshooting HIL or flat-sat electronic test systems for avionics and FSW validation
Strong hands-on skills with electronic test instruments (oscilloscopes, logic/network analyzers, power supplies, etc.)
Proficiency in Python for test automation (required); LabVIEW or MATLAB experience a big plus
Solid understanding of avionics interfaces (CAN, RS-422, Ethernet, SpaceWire, etc.) and RF fundamentals (telemetry/command systems, impedance matching, S-parameters, gain, noise figure)
Familiarity with embedded systems, real-time simulation environments, and test automation frameworks
Strong debugging and analytical mindset bridging hardware, firmware, and software
Experience with Git-based workflows, test data analysis, and structured documentation
Preferred
LabVIEW or MATLAB experience a big plus
