Manufacturing Engineer II

Long Beach, United States

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 Factory Test team designs, builds, and operates the infrastructure needed to test nearly every part of Terran R right here at our headquarters in Long Beach, CA. This centralized approach provides engineers and technicians with exposure to the entire product lifecycle across a wide range of part sizes and complexities. The scope and scale are significant, with test stands capable of handling millions of pounds of force. Team members lead multiple projects in parallel, avoiding silos and gaining broad technical experience without needing a background in aerospace. With high-impact campaigns ahead, including thrust structure and stage 2 testing, now is the time to join. You won't just execute, but you'll help shape and scale the test infrastructure required to meet the demands of a rapidly growing launch program.

About the Role:

Develop detailed process plans, work instructions, and work orders for the integration and test of flight hardware, including propulsion components, structural assemblies, fluid systems, and instrumentation
Collaborate with design and test engineers to provide design for testability feedback, ensuring hardware is robust and efficient in the test environment
Support test technicians and test specialists on the floor by troubleshooting issues, resolving non-conformances, and implementing corrective actions in real time
Coordinate with quality teams to ensure timely procurement and inspection of critical test components and verify all required calibrated equipment is in-date, documented on the work order, and available at time of use
Conduct Test Readiness Reviews (TRRs) to ensure all hardware is test-ready and risks are mitigated prior to test execution. Analyze process performance, test timelines, and drive continuous improvement across test campaigns
Maintain capacity and demand plans for upcoming test articles and support equipment

About You:

A Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or a related field
4+ years of experience in manufacturing, test engineering, or process development for aerospace hardware
Hands-on experience supporting hardware builds in development and test environments
Familiarity with pressure systems, instrumentation, and fluid system assembly. Experience with manufacturing documentation including work instructions, test plans
Comfortable working in fast-paced, hands-on environments with shifting priorities

Nice to haves but not required:

Experience supporting ATP, development, or qualification test campaigns
Familiarity with high-pressure fluid systems, cryogenic hardware, or propulsion test equipment
Experience with CAD tools (e.g., NX, SolidWorks) and fluid schematics for system layout and planning
Familiarity with PLM and ERP systems for tracking hardware and managing workflow
Understanding of AS9100 or ISO9001 quality management systems
