Lead HITL Test & Integration Engineer

Energy Jobline ZR; Long Beach (CA); On-site; USD 164,000 - 246,000; Full time

Job summary

Relativity Space in Long Beach, CA, is seeking a hands-on Test Engineer to design and maintain the ISP HITL test environment, integrating hardware, avionics, and software to validate flight software against real hardware.

You will build bench infrastructure, develop CI/regression pipelines, and debug complex failures across hardware and software, enabling rapid, credible engineering progress toward Terran R integration and launch.

Qualifications

• 7+ years in test engineering
• Experience architecting automated test frameworks for hardware, firmware, and software
• Strong software skills for test automation and validation pipelines
• Ability to own a complex test capability end-to-end
• Hands-on hardware and embedded systems experience
• Familiarity with Ethernet, UART, and SPI interfaces

Responsibilities

• 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, coordinating with subsystem responsible engineers to ensure hardware and software are designed for integration and test from the beginning
