Job Description:

Job Description 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 Team: The Stage Manufacturing team turns design into reality, owning the build of Terran R's primary structures. This isn't about turning the same bolt every day; it's about building the systems to build the rocket. Engineers and technicians work side by side, with deep collaboration and 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 here sets the blueprint for the future of scaled launch. About the Role: Own the large fusion welded assemblies work centers including 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 and related experience required Direct experience building welded products and experience supporting as an ME through a full product lifecycle. Strong 3D & 2D design/drafting skills per ASME Y14.5M (NX preferred) 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 Nice to haves but not required: Experience manufacturing large metallic structures with fusion welding experience (GTAW, GMAW) New product introduction of an aerospace hardware system into a manufacturing, test, and production system with proven success Experience in managing projects in a fast-paced environment At Relativity Space, we are committed to transparency and fairness in our compensation practices. Actual compensation will be determined based on experience, qualifications, and other job-related factors. Compensation is only one part of our total rewards package. Relativity Space offers competitive salary and equity, a generous PTO and sick leave policy, parental leave, an annual learning and development stipend, and more!
