Staff HITL Engineer

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. This is a hands-on integration and test role spanning hardware, software automation, and spacecraft-level validation. You will take the HITL environment from an empty rack to a running, automated, always-on validation system that proves our payloads, avionics, flight software, and interfaces work together as intended. You will build the bench, the software fixturing that exercises flight software against real and representative hardware, and the CI and regression infrastructure that continuously checks the system as it evolves. You won't just execute test procedures—you'll understand what each test proves, why it matters, and whether the result is actually credible. You will work shoulder to shoulder with engineers across the spacecraft. If you like owning a capability end to end, debugging across hardware and software boundaries, and being the reason the rest of the program can move quickly with confidence, this is that seat.
