Propulsion Manufacturing Engineer II, Combustion Devices

Long Beach, California

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:

​​We are looking for a talented Propulsion Manufacturing Engineer who will contribute to the development of Aeon-R Thrust Chamber Assembly hardware and manufacturing processes for the Terran-R vehicle. A high degree of autonomy, accountability, and initiative is required. As a Propulsion Manufacturing Engineer, you will own the manufacturing trades and then develop the processes for fabricating, testing, and delivering critical Aeon-R hardware and subassemblies. With a focus on manufacturability and integration, you will serve as the primary point of contact between the manufacturing and design teams as we develop and optimize Aeon-R hardware, ensuring that as-built hardware meets all aspects of the intended design. You will project-manage a wide variety of hardware in varying states of their manufacturing lifecycle, as well as develop processes and procedures for post-processing printed parts and recommend design adaptations to improve reliability and throughput. You have the passion, tenacity, and resolve to work through challenging issues unique to 3D printed and machined components.​ 

About You:

  • ​Bachelor's Degree in engineering or related technical field and 3+ years of direct experience working with thrust chamber assemblies or related hardware 
  • Ability to effectively investigate, resolve and screen hardware non-conformances
  • Ability to drive failure investigation efforts, root cause analysis and implementation of corrective action(s)
  • Ability to work with and train technicians
  • Knowledge of general assembly and test procedures, including tolerance stack-up analysis, structural proof testing and pressurized leak checks
  • Experience with Tooling design, including conceptualization, modeling and drafting, and detailed analysis 

Nice to haves but not required:  

  • Familiarity with castings and forging process technologies, as well as DFM related to these processes 
  • Demonstrated track record of delivering results leading complex manufacturing development projects from conceptual development through qualification / early production
  • Experience with team building and leading projects (directly and cross-functionally)
  • Experience with weld engineering, including joint design, process qualification, and NDE 

 

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.

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way.
