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 Mechanisms Manufacturing team at Relativity Space is currently in the design release and New Product Introduction phase for Terran R, our next generation, fully re-useable rocket.  This team handles a broad range of responsibilities, collaborating closely with vehicle design ,  supply chain,  test ,   production , and vehicle integration  to develop  electromechanical and pneumatic  hardware that supports rocket reusability. This includes key components like landing legs  mechanisms ,  grid fin actuators,  pneumatic separation and release mechanisms, and linear and rotary electromechanical actuators. Additionally, the  team   is  responsible for   developing and designing intricate processes, tooling, training technicians, and  optimizing  factory floor layouts.   Unique to Relativity, you will get to work across many teams to iterate and support development of the vehicle program.   To be successful in this role, you need to be a self-starter that can thrive in ambiguity,  identify   problems  and quickly resolve them, and provide definition to the previously undefined. You should have a commitment to quality ,  balance short-term and  long-term  solutions,  and  have  the discipline  required  to achieve  our  objectives .   About the Role: Own major mechanized assemblies and their child components from design release through test and successful integration onto the Terran R launch vehicle—lay out the build and test flow to ensure an efficient, high-quality product flow capable of scaling with time.  Drive the assembly’s build and test effort through design integration, part sourcing, assembly sequencing, mBOM development, build and test work order creation, and specification authoring.  Support workcenter development by considering assembly and test operations, safety, tooling and capital equipment requirements, and company operational goals. Provide hands-on support to the shop floor and production personnel, promptly addressing any issues that arise and offering upstream feedback to drive design for manufacturability. Analyze and disposition recurring manufacturing discrepancies and lead multi-disciplinary teams on root cause analysis and corrective actions. Foster a culture of critical thinking and imaginative problem-solving, constantly challenging the established norms in engineering and manufac
