The Role
Own the design and validation of mechanical products in Terran R's avionics system, collaborating with electrical engineers and utilizing CAD software.
Summary Generated by Built In

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’s structure intentionally combines 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, analysis, and test/validation of mechanical products within the Terran R avionics system. Mechanical products include electronics enclosures, vibration isolation, thermal management, and environmental protection devices
  • Collaborate with electrical engineers to design robust, high-performance printed circuit board assemblies
  • Perform preliminary sizing for static and dynamic loads and thermal environments.
  • Utilize 3D modeling and 2D drafting packages to deliver detailed designs with considerations for production and test
  • Validate designs for flight through rapid prototyping, analysis, and test campaigns

About You:

  • Minimum of 5+ years of experience in a full cycle mechanical design engineering role
  • Bachelor’s degree in mechanical engineering, aerospace engineering, or related field
  • Experience with 3D computer-aided design (CAD) software
  • Experience with structural and thermal analysis
  • Demonstrated project ownership and accountability with complex, multi-disciplinary technical projects

Nice to haves but not required:  

  • Experience with the design of electronic assemblies, batteries, and/or vibration isolation systems
  • Experience with finite element analysis methods
  • Applied knowledge of geometric dimensioning and tolerancing (GD&T)
  • Proficient with NX/Teamcenter CAD package

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.
