Company Overview:  

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:  

Relativity’s Integrated Performance teams ensure that our products work across all systems and disciplines, from trajectory design to aerodynamics to reliability analysis and beyond. Our groups size the Terran R rocket, design its missions for customer success, reliability, and reusability, and ensure that every system on the rocket and ground is engineered correctly for the demanding environments of launch and entry. Recently, we completed the preliminary design and analysis of Terran R including Relativity’s first-ever work on launch vehicle reusability, spanning advanced trajectory simulations, wind tunnel testing, and structures analysis, among many other projects.

About the Role: 

  • Develop and execute CFD analyses to solve novel challenges in vehicle entry heating and supersonic retropropulsion
  • Drive the design of major Terran R system elements – like fins, flaps, heat shields, and primary structure - to meet criteria for temperature and heating
  • Guide and mentor responsible hardware engineers to ensure hardware meets aerothermal requirements
  • Scope and develop aerothermal databases for ascent and entry, including uncertainty quantification, from multiple sources like CFD, empirical methods, and wind tunnel testing
  • Mature Relativity’s tools for developing and communicating aerothermal data, including custom and commercial code, databases, and signal processing tools

To be successful in this role, you should be self-motivated, adaptable, and able to contribute significantly to a fast-paced, integrated vehicle program. You should also be able to resolve ambiguity and drive projects to completion. Ideally, you have significant compressible flow, CFD, and High-Performance Computing (HPC) experience as well as a proven track record completing projects successfully in a highly collaborative environment.

On a weekly basis, you will be performing analysis, developing software tools, and supporting design teams. You will also use your strong organizational skills to properly manage the documentation and communication of your actions, recommendations, and decisions.

About You:  

  • A graduate degree (MS/PhD) in engineering or related field, and 3+ years relevant experience
  • Demonstrated proficiency in compressible flow and CFD, preferably on entry vehicles
  • Experience architecting and executing CFD workflows for external flow, preferably including engine plume simulation
  • Experience solving complex technical problems on integrated vehicles
  • Proficiency in Python and industry-standard CFD tools like FUN3D and Star-CCM+, including use of HPC clusters

Nice to Haves, but Not Required:  

  • 10+ years relevant experience across 2 or more program lifecycles
  • Experience with thermal protection system sizing & analysis using standard tools like FIAT, CHAR, MINIVER, or LAURA
  • Exposure to aerothermal wind tunnel and flight testing and instrumentation


We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.

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.
