Building reusable rockets to empower science and exploration.
The Role

At Relativity Space, we have two audacious goals: to build the next great commercial launch company with Terran R and to become America's leading force in additive manufacturing innovation. Both contribute to our long-term vision of creating humanity’s industrial base on Mars, paving the way for interplanetary life to expand the possibilities of the human experience. This journey begins right here on Earth – where we design, build, and fly rockets to deliver customer payloads to orbit. Terran R, our medium-to-heavy lift reusable rocket, fulfills the growing demand for launch capacity, thanks to our iterative approach that accelerates design, testing, and development while minimizing costs. While our groundbreaking research and development in 3D printing pushes the boundaries of large-scale additive manufacturing.

Your journey with us is more than just a job – it’s an opportunity to shape the future of aerospace technology, additive manufacturing, and the human experience alongside a community of passionate, creative individuals. Join us on this extraordinary journey, as we work together to transform our vision into reality.

About the Team: 

The Avionics team is responsible for all aspects of the electrical design on the rocket, from electronics, interconnects, associated mechanical design, testing and initial production. This team's scope includes the flight computers, power systems, RF systems, PCB design, autonomous flight safety systems, and telemetry. This team works on complex electrical systems that require modularity and flexibility, and are critical to the successful launch of Terran 1, Terran R, and beyond!   

About the Role:

  • Own the design, test/validation, and transition to production of avionics products within the Terran R avionics system
  • Collaborate with electrical engineers to design robust, high-performance printed circuit board assemblies
  • Coordinate with manufacturing to ensure avionics products are optimized for manufacturing.
  • 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
  • Familiarity with common electromechanical manufacturing process
  • Bachelor’s degree in mechanical engineering, aerospace engineering, or related field
  • Experience with 3D computer-aided design (CAD) software
  • Demonstrated project ownership and accountability with complex, multi-disciplinary technical projects

Nice to haves but not required:  

  • Experience with design of electronic assemblies and/or batteries
  • Applied knowledge of geometric dimensioning and tolerancing (GD&T)
  • Proficient with NX/Teamcenter CAD package
  • Previous work on launch vehicle or spacecraft
