Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Staff Integration and Test Responsible Engineer - **Company:** Relativity Space, Inc. - **Location:** Long Beach, CA, United States - **Experience:** Expert - **Salary:** $164,000.0 - $246,000.0 - **Contract:** Permanent contract - **Skills:** Automation of Tests, Configuration Management, Code Coverage, Software Debugging, Ethernet, Firmware, Routing, Software Tools, Requirements Traceability, Software Engineering, Software Systems, Test Execution Engine, Universal Asynchronous Receiver/Transmitter, Data Logging, Serial Peripheral Interface, Integration Tests - **Published:** August 10, 2026 - **Apply:** https://www.indeed.com/viewjob?jk=24ed6a336329e68a ## About the Role * 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 ## Description 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., * 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. ## Related Videos - [Creating a routing app with Google Maps API from scratch](https://www.wearedevelopers.com/videos/831-creating-a-routing-app-with-google-maps-api-from-scratch) - [The Gashlycrumb Tinies of AI Networking You Must Know (or Languish!)](https://www.wearedevelopers.com/videos/2067-the-gashlycrumb-tinies-of-ai-networking-you-must-know-or-languish) - [Playing Pong on a shoulder press machine](https://www.wearedevelopers.com/videos/100140-playing-pong-on-a-shoulder-press-machine) - [Why I Love End-2-End Tests and How To Get Them Right](https://www.wearedevelopers.com/videos/996-why-i-love-end-2-end-tests-and-how-to-get-them-right) - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) - [A Technical Introduction to Bitcoin's 2nd Layer- The Lightning Network](https://www.wearedevelopers.com/videos/15-a-technical-introduction-to-bitcoin-s-2nd-layer-the-lightning-network) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [Résumé-Driven Development: How IT trends affect the job market for software developers](https://www.wearedevelopers.com/magazine/59-resume-driven-development-how-it-trends-affect-the-job-market-for-software-developers) - [Top Characteristics of a Software Engineer](https://www.wearedevelopers.com/magazine/166-top-characteristics-of-a-software-engineer) - [Integration And E2E Testing: Are They Complementary or Interchangeable?](https://www.wearedevelopers.com/magazine/86-integration-and-e2e-testing-are-they-complementary-or-interchangeable) - [What is Software Engineering?](https://www.wearedevelopers.com/magazine/289-what-is-software-engineering)
