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 Manufacturing team owns all process development, fabrication strategy, and production equipment for Terran R, our next generation, reusable rocket. This team has a wide variety of responsibilities – from factory floor layout, to developing complex tooling for novel processes, and interfacing with our vehicle engineering team to heavily influence design of the rocket. We leverage our deep expertise to translate engineering requirements into highly optimized production lines, working cross functionally to consistently enhance the vehicle program. 

About the Role:

  • Support primary structure assembly and its child subassemblies from design release through ATP Test—lay out the build flow to ensure an efficient, high-quality product flow capable of scaling with time.  
  • Collaborate closely with a diverse team of engineers specializing in design, manufacturing, and reliability, as well as internal production teams and external vendors, leveraging their collective expertise to drive progress. 
  • 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 
  • 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, machining.  
  • Working knowledge of common manufacturing processes, tools, inspection methods and GD&T. 
  • Ability to perform trade studies using first principles and engineering fundamentals 
  • Highly self-motivated and able to prioritize and execute tasks in a high-pressure environment 

Nice to haves but not required:  


  • 6+ months progressive and related experience
  • Experience transitioning products from prototype to mass production 
  • 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! To see some of the benefits & perks we offer, please visit here.

What you need to know about the Los Angeles Tech Scene

Los Angeles is a global leader in entertainment, so it’s no surprise that many of the biggest players in streaming, digital media and game development call the city home. But the city boasts plenty of non-entertainment innovation as well, with tech companies spanning verticals like AI, fintech, e-commerce and biotech. With major universities like Caltech, UCLA, USC and the nearby UC Irvine, the city has a steady supply of top-flight tech and engineering talent — not counting the graduates flocking to Los Angeles from across the world to enjoy its beaches, culture and year-round temperate climate.

Key Facts About Los Angeles Tech

  • Number of Tech Workers: 375,800; 5.5% of overall workforce (2024 CompTIA survey)
  • Major Tech Employers: Snap, Netflix, SpaceX, Disney, Google
  • Key Industries: Artificial intelligence, adtech, media, software, game development
  • Funding Landscape: $11.6 billion in venture capital funding in 2024 (Pitchbook)
  • Notable Investors: Strong Ventures, Fifth Wall, Upfront Ventures, Mucker Capital, Kittyhawk Ventures
  • Research Centers and Universities: California Institute of Technology, UCLA, University of Southern California, UC Irvine, Pepperdine, California Institute for Immunology and Immunotherapy, Center for Quantum Science and Engineering
