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 Engine Manufacturing team is dedicated to delivering high-performance engines and advancing innovative manufacturing systems that continuously improve cost, quality, and lead time. You’re not just executing on designs; you actively provide input that shapes new hardware iterations and regularly interface with engineers to make critical decisions for the Aeon R program. Having successfully developed and refined processes for our initial development engines, the team is now focused on producing flight engines at rate for Terran R’s aggressive launch manifest.

About the Role:

  • Build & Commission new test assets and systems - incorporating fluid, mechanical, and electrical components – to unlock new capabilities or enhance existing ones. 
  • Author & Optimize test sequences, procedures, and operational processes to support first-article development and transition into high-volume production. 
  • Identify & Mitigate hazards in a fast-paced test environment to ensure the safety of all personnel. 
  • Mentor & Train production technicians on test equipment operation and best practices. 
  • Plan & Execute test campaigns in collaboration with Engineering to achieve Development, Qualification, and Acceptance test objectives. 

About You:

  • At minimum: High School Diploma or GED. 
  • 5+ years of relevant technical experience, including (but not limited to): 
    • Authoring & Executing Test Procedures 
    • Building Complex Fluid-Mechanical Systems 
    • Operating hazardous equipment with multiple sources of energy 
  • Proficiency with Basic Office Software (Excel, Word, Outlook, Slack). 
  • Demonstrated knowledge of safety standards, common test hazards, and appropriate mitigations. 
  • Desire to teach and mentor less experienced team members. 
  • Ability to precisely plan an activity, then execute according to that plan with minimal changes. 

Nice to haves but not required:  

  • Associates Degree or Trade Certifications in pertinent disciplines: e.g., Aviation/Automotive Mechanic. 
  • Familiarity with Industry Test Standards: e.g., SMC-S-016, MIL-STD-1540D, & MIL-STD-810G. 
  • In-depth knowledge and experience with test automation, data acquisition, and control systems. 
  • Knowledge of rocket engine components such as pumps, valves, regulators, check valves, as well as electric, pneumatic, and hydraulic valves, actuators, and other fluid system components. 
  • Desire to work hands-on, as part of a team, in both the development and production phases of a product lifecycle. 

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
