The Role
As a Senior Propulsion Engineer, you will design, analyze, and build propulsion hardware, collaborate with various teams, and ensure optimization of engine designs through analytical models. You will manage projects from concept to launch and test iterations of Aeon-R engines.
Summary Generated by Built In

At Relativity Space, we have two audacious goals: to build the next great commercial launch company with Terran R and to become America's leading force in additive manufacturing innovation. Both contribute to our long-term vision of creating humanity’s industrial base on Mars, paving the way for interplanetary life to expand the possibilities of the human experience. This journey begins right here on Earth – where we design, build, and fly rockets to deliver customer payloads to orbit. Terran R, our medium-to-heavy lift reusable rocket, fulfills the growing demand for launch capacity, thanks to our iterative approach that accelerates design, testing, and development while minimizing costs. While our groundbreaking research and development in 3D printing pushes the boundaries of large-scale additive manufacturing.

Your journey with us is more than just a job – it’s an opportunity to shape the future of aerospace technology, additive manufacturing, and the human experience alongside a community of passionate, creative individuals. Join us on this extraordinary journey, as we work together to transform our vision into reality.

About the Team:

The Propulsion Engineering team at Relativity Space is responsible for engines that will power the Terran R launch vehicle. We own the design from concept through successful launch and reuse and we work with our partner teams to manufacture, test and integrate those engines. We’re developing these engines in record time, going from initial sizing point of the Aeon R engine in early 2022 to a successful integrated, full duration hot fire test in late 2023. Over the next year, we will test 3 iterations of Aeon R, our booster engine, culminating in qualification for flight, and test our first iteration or Aeon R Vac, our second stage engine. As a part of this team, you will help build, test and iterate on the full product lifecycle of our Aeon-R engine systems from concept through launch and reuse.

What you’ll do:

You will be responsible for the overall layout, design, analysis, and build of hardware for our Aeon-R propulsion systems. You will work closely with other propulsion teams, the vehicle team, manufacturing/integration teams, and test teams to design, analyze, and optimize. Designs will be informed by both fluid and structural analytical and computational models. Engine assembly level layouts and trades will be weighed against weight, cost, lead time, and part count. To be successful in this role, you should be someone who thrives in ambiguity and is able to lead their own projects to completion.

About the Role:

  • Bachelor’s degree in a science, engineering, technology, or mathematics field
  • 5+ years of relevant experience, preferably with a complex engineering system
  • Experience with computer aided design (CAD) software
  • Understanding of mechanical design, fluid, thermal, and structural fundamentals
  • Experience with Finite Element Analysis (FEA)

About You:

  • Experience with Siemens NX and Teamcenter, specifically
  • Experience with large CAD model management, change management, and configuration management
  • Experience in the design of liquid propulsion components and systems
  • Familiarity with aerospace standards (AS, NAS, SAE, etc.)
  • We believe varied perspectives & backgrounds strengthen our team. Prior experience in aerospace is not required

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 We Do

A rocket company at the core, Relativity Space is on a mission to become the next great commercial launch company. Terran R, our medium-to-heavy lift reusable launch vehicle, will reliably deliver payloads to orbit on-time and on-budget for customers – meeting the needs of growing demand for space infrastructure. Leveraging the benefits of additive manufacturing to design, test, and iterate at a pace unmatched in the industry, we are changing the way rockets are built and flown.

Our long-term goal is to create humanity’s industrial base on Mars, paving the way for interplanetary life to fundamentally expand the possibilities of the human experience. The first step toward this vision starts here on Earth, by building the next great commercial launch company.

Why Work With Us

For 60 years, aerospace manufacturing has relied on fixed tooling and complex supply chains to slowly build rockets comprised of hundreds of thousands of parts. Leveraging advances in additive manufacturing, Relativity Space is strategically focused on reducing vehicle complexity, cost, and time to market.
