Lead Hardware Engineer; Controllers

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 launchcapacity. 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 beyondthe 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. Nowis a unique moment in time where it’s early enough to leave your mark on the product, the process, andthe 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.

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.

As the Lead Avionics Controllers Hardware Engineer, you will lead a small, nimble team of electrical engineers designing custom avionics controllers that interface with critical systems across the Terran R launch vehicle. Your team's controllers will command and control rocket engines, manage fluid and tank pressurization systems, interface with customer payloads, and operate separation mechanisms. You will guide your team through the full product lifecycle including initial design, board bring-up, design verification, qualification, initial flight production, integration, and vehicle operations.

You will work closely with cross-functional partner teams across propulsion, fluids, stage engineering, and GNC to ensure your controllers meet the demanding requirements of the overall vehicle. A strong candidate for this role will combine deep technical expertise in mixed-signal and analog circuit design with proven ability to mentor engineers, lead root cause investigations, and foster a culture of collaboration and high performance in a fast-paced environment.
