Relativity Space Intern Job Board is hiring an

Avionics Intern - Summer 2025

Long Beach, United States
Internship

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 the full lifecycle of electronics, harnessing, enclosures and secondary structure, instrumentation, and GSE hardware central to operating Relativity's rockets. The team designs, builds, tests, integrates, and operates the hardware which controls the rocket in flight, downlinks critical telemetry, keeps the public safe, and deploys our customers' payloads to orbit! Our hardware enables Relativity to reliably control our rockets while maintaining the flexibility to rapidly iterate our designs. As a member of this team, you will design innovative hardware solutions capable of surviving harsh launch and space environments. Your designs will support multiple vehicle systems such as sensors, propulsion, computing, actuation, energy management, and communications. 

As an Avionics Intern you’ll join one of six teams within Avionics: 

  • Avionics Hardware: Support the development of custom flight electronics for our rockets 
  • Avionics Integration: Support the system-level design of our suite of avionics including harness design, integration operations definition, and system architecture development 
  • Avionics Mechanical: Support the development of electronics enclosures, mounting hardware, trays, vibration isolators, and thermal management solutions 
  • Avionics Test & Operations: Support the development of our functional test systems, HITL test systems, and vehicle test and operations 
  • Avionics Manufacturing and Test: Support the development of our manufacturing and test processes, tooling, and test system development 
  • Avionics Safety & Certification: Support the regulatory certification of our flight safety system 

As the Avionics department is composed of many teams with many different areas of expertise, candidates from a wide variety of engineering backgrounds are encouraged to apply! 

Past intern projects (just a few examples!) 

  • Tested flight quick disconnects   
  • Implemented computer vision on the robots to implemented live depth data   
  • Worked on adding automated sanding/grinding capabilities to our print cells   
  • Worked on test stand infrastructure to help run tests more often and more efficiently  
  • Oversaw designing the PCB for the High Voltage Battery Management System (HVBMS)
