Staff Integration and Test Responsible Engineer
Relativity · Long Beach, California, United States
About this role
**Staff Integration and Test Responsible Engineer** **About the Team:** The Interplanetary Sciences Program is building a philanthropically funded Mars science orbiter targeted to launch in 2028. You will build the integrated hardware-in-the-loop (HITL) test capability that allows the spacecraft team to test early, continuously, and with real hardware, then carry that ownership into final spacecraft integration and test leading up to flight. **About the Role:** This is a hands-on integration and test role spanning hardware, software automation, and spacecraft-level validation. You will: • Design, build, and maintain the ISP HITL test environment end to end, including rack fabrication, avionics installation, breakout hardware, load emulation, harness fabrication and routing, and supporting test equipment • Build the simulation, data-acquisition, and control infrastructure that drives stimulus into the system, captures results, and allows flight software to be exercised against real and representative spacecraft hardware • Develop software fixturing, automated test frameworks, and CI/regression pipelines that validate every software change on hardware with automated pass/fail adjudication, regression detection, and clear failure reporting • Debug integrated failures across flight software, avionics, interfaces, harnessing, timing, communications, and test infrastructure until root cause is understood • Validate timing-sensitive behavior and interfaces across sensors, actuators, payloads, avionics, and communication buses • Establish dashboards, telemetry views, configuration control, and test procedures that make system health, test coverage, anomalies, and requirements traceability clear • Drive final integration and test of flight hardware leading into launch **About You:** • Degree in computer, electrical, aerospace, or related engineering field, or equivalent hands-on experience • 7+ years of experience in test engineering, including architecting automated test frameworks for integrated hardware, firmware, and software systems • Strong, current software skills for test automation, tooling, and validation pipelines • Track record of building test automation and CI/regression infrastructure from the ground up • Hands-on hardware and embedded systems experience, including bench troubleshooting and familiarity with interfaces such as Ethernet, UART, and SPI • Demonstrated ability to own a complex test capability end to end and coordinate effectively across engineering teams **Nice to Haves:** Experience with HITL systems, spacecraft/launch vehicles, harnessing and cable fabrication, or establishing test practices in fast-moving engineering environments.
