Full Job Description

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 Role

The Assembly & Test Technician is responsible for executing pressure testing, mechanical assembly, precision cleaning, and thermal insulation work. You will work alongside leadership and engineering to conduct pressure testing, mechanical assembly, and precision cleaning work on various fluid assemblies for the Terran R rocket and Aeon R rocket engine.

This is a 2nd shift position with a standard schedule of 3:00 PM - 1:30 AM PT, Monday through Friday. The role includes a 10% shift differential added to the base pay. Please note that this position is structured around a baseline expectation of a 50-hour workweek, which may include occasional overtime as needed to meet operational goals.
Key Responsibilities

Use torque wrenches and other tools to assemble critical pressure seals, fittings, flanges, and other hardware to facilitate pressure testing
Operate high-pressure hydraulic and hydrostatic pumps within a blast enclosure to safely pressure test fluid components and assemblies
Use sonicating immersion cleaning tanks, flushing equipment and pressure washing equipment to precisely clean assemblies and components to meet critical standards for handling liquid oxygen
Use insulating foams and fiberglass insulation to thermally insulate sensitive components from the environment
Escalate production blockers to leadership for timely resolution
Work alongside engineering to resolve technical hardware non-conformances and to implement corrective actions
Identify opportunities for continuous improvement and work alongside leadership and engineering to implement them

Must Haves:

Experience working with heavy parts, mechanical assembly, and fastening
Experience using fluid equipment such as sonicating immersion cleaning tanks, flushing equipment, pressure washing equipment, or high-pressure hydrostatic proof testing pumps
Strong communication skills
Strong documentation ethic and organization skills

Nice to Haves:

Proficiency in pressure testing and precision cleaning for aerospace products
Experience operating in a fast-paced aerospace production environment
