About The Position

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 Test & Operations team is responsible for testing avionics hardware and systems across the entire product lifecycle of Terran R: component-, subsystem-, and vehicle-level. As an Avionics Test Engineer at Relativity Space, you will be responsible for designing, developing, and executing avionics testing strategies for our rocket systems. This includes working closely with the avionics design team to identify and troubleshoot any issues and developing automation and testing infrastructure to improve efficiency and effectiveness. About the Role: Develop frameworks and infrastructure to conduct qualification and acceptance testing of Avionics components on the Terran R launch vehicle Design equipment to facilitate Avionics component testing: simulation circuits, auxiliary test equipment, test harnesses, mechanical fixtures and enclosures, and system validation tools Work with hardware design engineers and software engineers to derive test requirements and methodologies Create and maintain test plans and procedures for avionics systems Integrate, commission, and operate test rack hardware and software to support component- and system-level functional testing
