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 Additive Development team at Relativity Space will develop, create, and operate the most advanced additive manufacturing technologies in the world. This best-in-class team makes sure that the infrastructure, materials, tools, and equipment are in place for us to rapidly iterate and print. The powder-based manufacturing team is crucial to manufacturing Aeon-1 for first launch and to developing and demonstrating groundbreaking technologies, design, and approaches for Aeon-R.

About the Role:

  • Develop additive manufacturing processes to continuously improve manufacturing cost, quality, and lead time
  • Produce additively manufactured components that rapidly enable high performance liquid propulsion hardware
  • Holistically own and optimize the total manufacturing process including, design for additive, build file programing, manufacturing work instructions, and quality verification
  • Develop, optimize, and productionize process parameters for various alloys and machine systems and develop tools and techniques to accelerate and automate that process
  • Execute material failure investigations, conduct root cause analyses, and implement corrective actions
  • Develop new tools, techniques, and applications that automate existing processes and standardize on performance-based benchmarks
  • Support material and process team with characterization and qualification of various alloys

About You:

  • Experience implementing new engineering processes in school projects, internships, and/or clubs
  • Experience communicating technical information within a diverse team
  • Experience with at least one of the following:
    • CAD
    • Design for additive manufacturing
    • GD&T 
  • Exposure to concepts behind laser powder bed fusion, printer primary subsystems, and post-processes 
  • 0-1+ years of experience working in aerospace, medical devices, or ISO environments
  • 0-1+ years of experience in mechanical or materials engineering related roles
  • 0-1+ years of experience working on metallic additive manufacturing
  • Exposure to typical manufacturing execution systems (MES) and quality management systems 

Nice to haves but not required:  

  • Advanced degree (MS) in Material Science, Materials Engineering, Metallurgy, Mechanical Engineering, or another related field
  • Familiarity with processing large datasets and statistical data analysis software such as R, JMP, or Minitab 
  • Familiarity with design and operation of liquid propellent engine systems 
  • Serve as materials subject matter expert on powder bed fusion team 
  • Proficient at oriented programming (Python, JS, C#, or Java) 
  • Experience in leveraging API’s and real-time data sources to build applications in a production environment 
  • Developing APIs and building applications on them in a production environment 
  • Six Sigma/Lean manufacturing training 

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.

Hiring Range:$90,000—$113,000 USD
