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.
About the Role:
As a Propulsion Integration Engineer, you will own and develop the processes for the builds of major Aeon-R subassemblies an engine integration. With a focus toward manufacturability, you will serve as the main point-of-contact between the manufacturing and design teams as we develop and optimize Aeon-R hardware and packaging, ensuring as-built hardware meets all aspects of the intended design.
You will project manage a wide variety of hardware in varying states of their manufacturing lifecycle. You will develop processes and procedures for post-processing of 3D printed parts and recommend design adaptations to improve reliability and throughput. You have the passion, tenacity and resolve to work through challenging issues unique to 3D printed and machined components. This role requires a high degree of cross functionality between design, manufacturing, and test teams.
About You:
- Degree in engineering or related technical field and 6+ years of relevant experience
- Ability to effectively investigate, resolve and screen hardware non-conformances
- Ability to drive failure investigation efforts, root cause analysis and implementation of corrective action(s)
- Knowledge of general assembly and test procedures, including tolerance stack-up analysis, structural proof testing and pressurized leak checks
- Experience with GD&T, CAD, and analysis tools including tool design
Nice to have but not required:
- Experience working in a propulsion development program
- Familiarity with a fast-paced, high-mix manufacturing environment, working hands-on with hardware
- Experience in Additive Manufacturing, Subtractive Manufacturing, Machining, and associate precision inspection techniques
- Experience working with and managing vendors and external suppliers to get parts made quickly and reliably
