Job description

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:

As an electrical hardware engineer on the Avionics team, you will design, test, and analyze custom electronics on the Terran R launch vehicle. You will oversee hardware development through the entire product lifecycle from concept to flight maturity to include initial design, board bring-up, design verification, qualification, initial flight production, integration, and vehicle operations. You will work with cross-functional partner teams across the company to help the team make the best possible decisions for the overall vehicle. A strong candidate for the role will have a deep technical background in electronics design and sound project management skills to ensure the hardware project is both reliable and on‑schedule to support Terran R's launch!

About You:

• Bachelors degree in Electrical Engineering, Computer Engineering, or a related field
• 5+ years of experience in electronics designed for harsh environments and mission‑critical applications such as launch vehicles, spacecraft, aircraft, or robotics
• Familiarity with eCAD software such as Altium or equivalent
• Experience with hardware bring‑up, validation, debugging, and data analysis
• Experience with board‑level design from concept to manufacturing
• Experience working with highly cross‑functional teams (mechanical, thermal, electrical, software, etc.) to develop integrated electronics solutions

Nice to haves but not required:

• Familiarity with embedded software development and integration for avionics systems
• Experience with design for reliability and manufacturability of avionics hardware and systems
• Technical expertise in motor drives and control, DC‑DC converters, load switches, high voltage DC electronics

Hiring Range and Leveling:

Engineer I: $106,000 - $146,500 USD

Engineer II: $126,000 - $172,500 USD

Senior Engineer: $148,000 - $203,500 USD

Leveling and compensation will be finalized after the interview process, based on an evaluation of job‑related knowledge and skills, education, and experience.

Compensation and Benefits:

Compensation is only one part of our total rewards package. Relativity Space offers competitive salary and equity, a generous PTO and sick leave policy, parental leave, an annual learning and development stipend, and more!
