Avionics Engineer Intern - Fall 2025

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 R, and beyond! 

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)  
• Helped set up an anomaly detection framework for stargate printers   
• Printed rocket engine parts!   

Skills/Competencies we're looking for: 

• Obtaining BS or MS degree in aerospace engineering, mechanical engineering, electrical engineering, computer engineering, manufacturing engineering, computer science, or related field. 
• Familiarity with at least one of the following areas: 
  • Electronics design and/or PCBA design 
  • Electrical harness design and routing 
  • Mechanical design experience with CAD modeling software 
  • Bring-up and integration of the electrical system of large-scale systems 
  • Development of electrical and mechanical test fixtures and tools 
  • Design for manufacturing, manufacturing process development, manufacturing execution systems 
• We believe varied perspectives & backgrounds strengthen our team. Prior experience in aerospace is not required 

We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
