🚀 Senior Power Electronics Engineer

Overview

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. Relativity is a place where autonomy, ownership, and impact exist at every level. You’ll solve 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 and see your work come to life in record time.

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 gaining 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’s structure intentionally combines avionics design, manufacturing, and test to enable rapid iteration and feedback loops. Engineers are deeply embedded with propulsion, GNC, fluids, and stage engineering to ensure seamless integration and operation. You’ll help shape Terran R's fundamental avionics architecture and have a high degree of ownership on components that will fly.
