Senior Propulsion Technician II, First Shift

Overview

Long Beach, California

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. Joining Relativity means becoming part of something where autonomy, ownership, and impact exist at every level. Here, you’ll solve problems that haven’t been solved before, helping develop a rocket, a factory, and a business from the ground up.

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 gaining momentum.

The most meaningful work of your career is waiting. Join us.

The engine manufacturing department’s mission is to produce high performing products and manufacturing systems by continuously innovating on cost, quality, and lead time. Through cross-functional collaboration, accountability, and a focus on safety we support the Terran R program. We provide design feedback on new hardware iterations, develop new manufacturing methods and systems, and build engine and vehicle hardware for testing prior to our first launch.

Highlights from the last 6 months include the MDC of the first Aeon-R engine, thousands of hours of PBF printing, building and testing over 50 valves of 26 different iterations, and implementing large-scale process improvements.

Senior Propulsion Technician will be on the front line of fabrication and assembly of the Aeon-R engine, as well as scaling manufacturing operations. This is a unique opportunity to join an experienced team and build the skills necessary to create robust and highly tuned engine systems. You will be hands-on with hardware from day 1, so strong attention to detail and drive to grow your skills are necessary.

You will interpret work instructions and engineering drawings to complete tasks, while providing feedback to the team on necessary improvements. This role involves in-house processes and support resources such as precision cleaning, hydrostatic proof testing, flow testing, and engine assembly.
