Propulsion Integration Engineer Intern

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 Engine Manufacturing team is dedicated to delivering high-performance engines and advancing innovative manufacturing systems that continuously improve cost, quality, and lead time. You’re not just executing on designs; you actively provide input that shapes new hardware iterations and regularly interface with engineers to make critical decisions for the Aeon R program. Having successfully developed and refined processes for our initial development engines, the team is now focused on producing flight engines at rate for Terran R’s aggressive launch manifest.

What you'll do: 

• Define, architect, and establish an optimized, efficient product flow of flight hardware through the Factory 


• Identify capital tooling and work center capability needs and lead the efforts of standing up key Factory capabilities


• Help drive the development of business tools and processes that will be used to manufacture the first launch vehicle


• Define and pilot the long-term ERP, MES, and QMS solutions that will enable high-quality, efficient vehicle manufacturing

Skills/Competencies we're looking for: 

• Obtaining BS or MS in aerospace, mechanical, manufacturing, or industrial engineering


• Interest in typical manufacturing execution systems and quality management systems


• To be successful in this role, you need to be able to thrive in ambiguity, identify problems and quickly resolve them, and provide definition to the previously undefined


• You will need to balance a scrappy, get-it-done attitude with a vision for the long-term processes required for scaling and efficiency!


• We believe varied perspectives & backgrounds strengthen our team. Prior experience in aerospace is not required.  

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!
