Senior Build Reliability Engineer, Fluids

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 Reliability team at Relativity Space ensures quality is built into every stage of the Terran R design and production process, embedding reliability from the very beginning. The team works directly with design, manufacturing, test, and launch teams to stay close to the hardware, understand constraints, and proactively shape decisions. As the program moves from development into production and scaled operations, this is the time to establish the right processes, controls, and inspections without slowing progress.

The team plays a key role in balancing risk, fostering a culture of ownership, and making sure speed never comes at the cost of reliability. Success means creating a quality system that scales with the Terran R program and Relativity as a whole.

About the Role:

Support design activities including drawing standardization, design for manufacturability (DFM), configuration management, and fluid system requirements to ensure hardware quality throughout production and integration.

Review work instructions, develop processes, and establish standard rework and repair documentation to support efficient and reliable fluid system manufacturing, assembly, and installation.

Oversee in-process build verification, fluid system inspections, tubing and piping installations, and coordination of traveled work to ensure quality standards are maintained throughout production.

Manage nonconformance processes, as-built verification, root cause investigations, and corrective actions to resolve manufacturing and fluid system issues while minimizing impacts to production schedules.

Drive initiatives to improve quality across fluid system manufacturing and integration, including developing specifications, establishing inspection checklists, improving cleanliness controls, and supporting pressure and leak test verification.

Develop strong working relationships with Engineering, Manufacturing, Integration, and Test teams to identify risks, resolve technical challenges, and ensure successful fluid system assembly and integration.

About You:

Bachelor of Science degree in Engineering or another STEM field and a minimum of 5 years of experience as a Manufacturing or Quality Engineer in a fast-paced manufacturing environment.

Extensive experience interfacing with design engineering, manufacturing, production, integration, and test  knowledge of aerospace manufacturing, fluid system assemblies, tubing and piping installations, and associated quality…
