🚀 Senior Manufacturing Engineer, Welding

About Relativity Space

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. Achieving commercial success with Terran R will unlock new opportunities to advance science, exploration, and innovation, pioneering progress that reaches beyond the known.

About the Team

The Stage Manufacturing team turns design into reality, owning the build of Terran R’s primary structures. Engineers and technicians work side by side, collaborating with deep real‑time feedback to shape how we build better and faster. With a manifest and a launch date, it’s up to the team to deliver on Terran R: solving challenges in real time, optimizing for scale, and constantly improving processes. As the vehicle evolves, so will the factory, with opportunities to apply automation, machine learning, and advanced technologies. What we build sets the blueprint for the future of scaled launch.

About the Role

• Own the large fusion welded assemblies work centers including grid fins, domes, transfer tubes and future components making them able to meet rate production requirements.
• Partner with a diverse team of engineers and technicians to create a tooling suite and robust process for each fusion weld on the vehicle.
• Create work instructions, specifications, and best practices across multiple high‑fidelity processes. Help standardize processes across the manufacturing team.
• Help establish the stations within the inaugural work cell by considering assembly operations, tooling and capital equipment requirements, and rate targets.
• Support the shop floor through live issue resolution and provide upstream feedback as we innovate the next generation of manufacturing technology.
• Provide Design for Manufacturing feedback to structures teams during the development phase and through the first prototype and flight builds.

About You

• Bachelor’s degree in aeronautical, mechanical engineering, or other engineering discipline with 5+ years progressive related experience.
• Excellent interpersonal skills with the ability to interface with engineering and manufacturing groups to understand process constraints and provide design inputs for improved manufacturability.
• Strong engineering fundamentals in statics, mechanics of materials, process improvement/factory design, fastening and joining, basic metallurgy, machining.
• Working knowledge of common manufacturing processes, tools, inspection methods and GD&T.
• Ability to perform trade studies using first principles and engineering fundamentals.
