Propulsion Integration & Test Engineer II, Second Shift

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 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: This is a second shift position starting at 2pm PT

Own hardware from design release through build, test, and delivery for engine or vehicle systems, taking full responsibility for execution readiness and product quality across subassemblies and integrated systems
Develop and release detailed build flows, work instructions, and test procedures to enable repeatable, high-quality execution across first builds and maturing programs
Support first article builds in a fast-paced environment, focusing on manufacturability, repeatability, and quality, while developing scalable processes that enable a smooth ramp to higher production rates
Provide hands-on floor support during build and test, resolving issues in real time, incorporating technician feedback, and driving continuous improvement across hardware flow and process discipline
Coordinate across design, supply chain, production, and test teams to ensure part readiness, tooling availability, schedule alignment, and smooth handoffs between build stages
Contribute to the development of long-term manufacturing systems and infrastructure, including tooling strategies, ERP/MES workflows, and production documentation standards

About You:

Degree in engineering or a related technical field, with 2+ years of hands-on experience building and testing hardware in a manufacturing or integration environment
Skilled at investigating hardware issues, resolving non-conformances, and driving root cause analysis with corrective actions implemented effectively
Familiar with general assembly and test procedures, including tolerance stack-up analysis, structural proof testing, and pressurized leak checks
Comfortable interfacing across design, manufacturing, supply chain, and test teams to ensure hardware quality and schedule alignment
Self-starter who can define and roll out new processes from scratch, working collaboratively with technicians, engineers, and external vendors
Proficient in GD&T, CAD, and basic design or test analysis, with experience in at least two of the following: LOX cleanliness, leak checking, sensor checkouts, tube bending, tool design, crane operations, or subassembly builds

Nice to haves but not required:

Experience supporting new aerospace product introduction or transitioning hardware from prototype to production, especially in a high-rate or scaling environment
Experience directly authoring and executing test procedures, including acting as a test conductor for integrated system verification
Familiarity with hazardous operations, fluid system safety, or test execution involving pressurized or high-risk environments
Experience in a fast-paced and lean environment, including direct vendor engagement, tool development, or leading a small team through an ambiguous build or test effort
