Senior Avionics Systems Integration & Test Engineer

At Relativity Space, we're building rockets to serve today's needs and tomorrow's breakthroughs. Our Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity. But that's just the start. Achieving commercial success with Terran R will unlock new opportunities to advance science, exploration, and innovation, pioneering progress that reaches beyond the known.

Joining Relativity means becoming part of something where autonomy, ownership, and impact exist at every level. Here, you're not just executing tasks; you're solving problems that haven't been solved before, helping develop a rocket, a factory, and a business from the ground up. Whether you're in propulsion, manufacturing, software, avionics, or a corporate function, you'll collaborate across teams, shape decisions, and see your work come to life in record time. Relativity is a place where creativity and
technical rigor go hand in hand, and your voice will help define the stories we're writing together. Now is a unique moment in time where it's early enough to leave your mark on the product, the process, and the culture, but far enough along that Terran R is tangible and picking up momentum. The most meaningful work of your career is waiting. Join us.

About the Team:

The Avionics team is responsible for all aspects of the electrical design on the rocket, from electronics, interconnects, associated mechanical design, testing and initial production. This team's scope includes the flight computers, power systems, RF systems, PCB design, autonomous flight safety systems, and telemetry. This team works on complex electrical systems that require modularity and flexibility, and are critical to the successful launch of Terran R, and beyond!

About the Role:

• Oversee avionics system-level design verification and validation test activities: development of test matrices and test plans, creation of fixtures and tooling, and identification of pass/fail criteria
• Develop manuals, abort/redline/blueline criteria, data dashboards, and GUIs to ensure avionics health and performance during engine and vehicle integration, test, and launch activities
• Design, build, validate, and operate the electrical ground support equipment (EGSE) that provides power and communications to the Terran R launch vehicle throughout the product lifecycle (build, integration, test, launch, and recovery)
• Apply systems engineering methodologies to identify and design EGSE subsystems (DC power distribution, networking, safety systems, internal and external interfaces) and system-level test/simulation platforms
• Coordinate hardware readiness reviews of all avionics hardware and systems: build and integration readiness, component- and vehicle-level test status, and open issues and non-conformances
• Support test and launch activities on behalf of Avionics: coordination of integration and test activities between Engineering and Operations, anomaly investigations, post-test/launch data reviews, and on-console support

About You:

• Undergraduate or graduate degree (BS/MS/PhD) in Electrical Engineering, Computer Engineering, Computer Science, Aerospace Engineering, or a related field
• 6+ years of experience in electrical systems design/analysis; system-level test; systems engineering; or equivalent
• Experience with complex system-level operations (vehicle-level test programs, launch operations, large-scale manufacturing, etc.)
• Familiarity with basic electrical test equipment (DMMs, oscilloscopes, power supplies, etc.)
• 25-50% travel to our Stennis and Cape Canaveral sites to support EGSE infrastructure bring-up and vehicle test/launch operations
• Demonstrated problem-solving and communication skills

Nice to haves but not required:

• Familiarity with programming languages for data acquisition, control, and analysis (Python, MATLAB, LabVIEW, or equivalent)
• Working knowledge of fundamentals of launch vehicles
• Experience with data analysis and visualization, especially with timeseries data and SQL databases
• Experience with production work order or MES systems
