Staff Integration and Test Responsible Engineer

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 and fed back to the responsible design teams.

Validate timing-sensitive behavior and interfaces across sensors, actuators, payloads, avionics, and communication buses, including longer-duration and soak testing where appropriate.

Establish dashboards, telemetry views, configuration control, and test procedures that make system health, test coverage, anomalies, and requirements traceability clear to the broader engineering team.

Drive final integration and test of flight hardware leading into launch, coordinating with subsystem responsible engineers to ensure hardware and software are designed for integration and test from the beginning.

About You:

Degree in computer, electrical, aerospace, or a 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

A track record of building test automation and CI/regression infrastructure from the ground up, including telemetry/logging, automated pass/fail, and continuous test execution

Hands-on hardware and embedded systems experience, including bench troubleshooting with standard electronics equipment and familiarity with interfaces such as Ethernet, UART, and SPI

Demonstrated ability to own a complex test capability end to end, drive integrated hardware/software failures to root cause, and coordinate effectively across engineering teams

Nice to haves but not required:

Experience standing up a test bench, HITL system, SIL/HIL environment, lab automation capability, or integrated test platform from scratch

Experience with spacecraft, launch vehicles, satellites, robotics, autonomous systems, aircraft, vehicles, medical devices, industrial equipment, or other high-reliability hardware

Hands-on experience with harnessing, cable fabrication, breakout boards, rack wiring, or test equipment setup

Experience helping establish test practices, tools, or team processes in a fast-moving engineering environment
