The Avionics Test Engineer will play a key role in testing avionics systems and components across both hardware and software, including environmental qualification activities. This role focuses on developing hardware-in-the-loop test equipment, creating and executing test plans and procedures, and troubleshooting test failures to ensure reliable, flight-ready avionics for an advanced space plane program.

• Support comprehensive testing of avionics systems and components at both hardware and software levels, including environmental qualification testing.
• Develop hardware-in-the-loop (HIL) test equipment and test benches to validate avionics performance and reliability.
• Create detailed test plans and procedures that cover component-level and system-level testing requirements.
• Execute tests according to established plans and procedures, carefully documenting results and observations.
• Troubleshoot test failures and anomalies, identify root causes, and propose corrective actions in collaboration with engineering teams.
• Use scripting tools and languages, such as LabVIEW and Python, to automate tests, data collection, and analysis.
• Apply environmental and electrical qualification standards, including RTCA-DO-160 and MIL-STD-461, to ensure compliance of avionics hardware.
• Collaborate closely with the avionics team and other engineering disciplines to integrate test results into design improvements and verification activities.
• Maintain organized test documentation, including test reports, configurations, and traceability to requirements.
• Contribute to continuous improvement of test methodologies, tools, and processes to enhance test coverage and efficiency.

• Bachelor of Science degree in Engineering from an accredited university.
• At least 8 years of experience in engineering, with a focus on testing of electronic or avionics systems.
• Hands-on experience with component-level and system-level testing of complex hardware and software systems.
• Proficiency in developing and using hardware-in-the-loop (HIL) test equipment and test benches.
• Experience in test plan and test procedure development for avionics or similar systems.
• Strong LabVIEW and/or Python development skills for test automation and data analysis.
• Experience applying environmental and electrical qualification standards such as RTCA-DO-160 and MIL-STD-461.
• Ability to troubleshoot test failures, analyze data, and identify root causes in a structured and systematic manner.

• Experience working in avionics, aerospace, or other safety-critical domains.
• Familiarity with scripting for automated testing and report generation.
• Strong documentation skills and attention to detail in recording test setups, procedures, and results.
• Ability to collaborate effectively with multidisciplinary engineering teams.
• Commitment to safety and quality in all testing activities.

This role directly supports the avionics team working on an advanced space plane program, offering the opportunity to contribute to a vehicle approaching launch. The team places a strong emphasis on a culture of safety, with Safety Above All as a core value. Work is primarily performed in a laboratory and engineering environment that includes test benches, hardware-in-the-loop systems, and specialized test equipment for environmental and electrical qualification. The position involves close collaboration with other engineers, structured test processes, and a focus on delivering high-quality, reliable avionics systems suitable for spaceflight.
