Senior Avionics 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 the full lifecycle of Terran R’s nervous system, designing, building, testing, installing, and operating the hardware that connects and controls every major electrical system on the vehicle and ground. The team leverages close partnership between avionics design, manufacturing, and test to enable rapid iteration and feedback loops. Engineers are deeply embedded into other functions within Relativity, working closely with propulsion, GNC, fluids, and stage engineering teams to ensure seamless integration and operation. Now is a unique time to join: you’ll get to help shape Terran R's fundamental avionics architecture and be given a high degree of ownership on components that will fly. 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 About You: Undergraduate or graduate degree (BS/MS/PhD) in Electrical Engineering, Computer Engineering, Computer Science, Aerospace Engineering, or a related field 5+ years of experience with electronics hardware simulation or test Experience with data acquisition and control system platforms such as NI, Beckhoff, or similar Experience automating electronic test equipment such as power supplies, DMMs, oscilloscopes, signal generators, and electronic loads Familiarity with common communication protocols such as Ethernet, CAN, UART, SPI, etc. Strong communication and interpersonal skills Nice to have, but not required: Experience with a schematic capture PCB design tool such as Altium Designer Experience with analog sensors such as pressure transducers, RTDs, and accelerometers Experience with embedded software development and integration for avionics systems Experience with scripting languages such as Python or MATLAB for data acquisition/recording and analysis Familiarity with wire harness design Familiarity with CAD tools such as NX At Relativity Space, we are committed to transparency and fairness in our compensation practices. Actual compensation will be determined based on experience, qualifications, and other job-related factors. Compensation is only one part of our total rewards packag ...
