Job description

At Relativity Space, we’re building rockets to serve today’s needs and tomorrow’s breakthroughs. OurTerran 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 newopportunities 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 mostmeaningful 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:

• Own the design, routing, and integration of electrical wire harnessing within the Terran R Avionics System from conception to qualification and production, including connectors, cable, and supports
• Collaborate across various disciplines including structures, electrical hardware, propulsion, and software to optimize system-level avionics design through architecture trades and requirements definition
• Utilize 3D modeling, 2D drafting, and electrical design packages to deliver detailed designs with considerations for production and test
• Validate designs for flight through rapid prototyping and test campaigns
• Support vehicle-level integration activities by defining avionics systems integration operations, checkouts, and test plans

About You:

• Bachelor's degree in Mechanical Engineering, Electrical Engineering, Aerospace Engineering, or a related field
• 5+ years of experience in a full lifecycle design engineering role
• Experience with electrical harness design and mechanical routing in 3D CAD software
• Experience with the integration and test of complex, multi-disciplinary electrical systems

Nice to haves but not required:

• Proficiency with NX CAD and Teamcenter
• Experience with Zuken E3 electrical design software
• Experience with scripting and software development to support hardware bring-up activities (e.g. Python, LabView, C/C++)
• Experience developing electrical and mechanical test fixtures, tools, and production harnessing
• Experience working with hardware-in-the-loop (HIL or HITL) test systems

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 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!To see some of the benefits & perks we offer, please visit here.
