Summary Generated by Built In

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:

  • Support manufacturing and development of a major mechanized assembly and subcomponents. Assist in driving efficient production by helping to develop new manufacturing processes and optimizing existing ones. 
  • Drive the assembly’s build 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 support multi-disciplinary teams on root cause analysis and corrective actions. 
  • Foster strong collaborative relationships with design, production, supply chain and quality assurance, facilitating effective communication and coordination to ensure alignment with company objectives and successful execution of manufacturing processes. 

About You:

  • BS degree in aerospace, mechanical, manufacturing engineering or other related discipline with 1+ years of experience building and testing hardware in a manufacturing environment. 
  • Experience authoring work instructions and/or test procedures to build and validate interdisciplinary mechanical, electrical, and pneumatic assemblies.  
  • Experience interfacing with design engineering, manufacturing, and production personnel. 
  • Experience supporting large process and/or quality improvements with large scope of ownership. 
  • Experience designing tooling or owning tooling development as a manufacturing representative. 
  • Experience in at least 2 of the following:  
    • Machining, precision drilling, mechanical fastening, and torquing operations, pneumatic and/or electromechanical assembly, electrical and/or pneumatic functional checkouts, integrated testing, tool design and fab, subassembly workcenter development, high voltage systems (320V+), high pressure pneumatic systems. 

Nice to haves but not required:  

  • A proactive self-starter with a proven track record of defining and implementing manufacturing processes, driving execution across diverse teams, and successfully managing and delivering manufacturing projects in fast-paced, production-driven environments. 
  • New product introduction of an aerospace hardware system into a manufacturing, test, and production system with proven success.  
  • Working knowledge of rocket subsystems including structures, mechanisms, high pressure gas systems, and/or avionics.  
  • Strong understanding GD&T and drafting principles.
