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 computational fluid dynamics (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
- Size thermal protection systems (TPS) for flight
- Support re-usable TPS material development and testing
- Mature Relativity’s tools for developing and communicating aerothermal data, including custom and commercial code, databases, and data 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, thermal analysis, and conjugate heat transfer 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:
- Undergraduate degree in engineering or related field
- 2+ years relevant experience
- Proficiency in compressible flow and thermal analysis, preferably on entry vehicles
- Experience executing CFD workflows for external flow, preferably including engine plume simulation
- Experience solving cross-disciplinary design problems on integrated vehicles
Nice to Haves, but Not Required:
- Graduate degree in engineering or related field
- 5+ years relevant experience across 1 or more program lifecycles
- Experience with thermal protection system sizing & analysis using standard tools like FIAT, CHAR, MINIVER, or LAURA

What the Team is Saying
What We Do
Welcome to Relativity Space, where we're rewriting the rules of rocketry. We have built and launched the world’s first 3D printed rocket, Terran 1, and are now bringing to market Terran R, our reusable medium-to-heavy-lift launch vehicle. Our iterative development approach revolutionizes the process from design to flight, ensuring we can scale to meet customer needs.
Our focus is clear: provide exceptional launch services that are highly competitive in the market. We design and manufacture cost-effective, high-performance, and reusable rockets at an unprecedented pace and scale – setting a new industry standard.
At Relativity Space, we have two audacious goals: build the next great commercial launch company with Terran R, and become America’s leading force in additive manufacturing innovation. Both ladder up 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. That journey begins right here on Earth—designing, building, and flying rockets to deliver customer payloads to orbit.
A medium-to-heavy lift reusable rocket, Terran R is designed to meet the ever-growing need for launch capacity. Our iterative approach accelerates the design, test, and development processes, enabling high-volume performance and reliability, with lower costs and shorter time to market. Our 3D printing research and development is at the bleeding edge, setting the standard for a new era of large-scale additive manufacturing.
Why Work With Us
We believe in a future where interplanetary life fundamentally expands the possibilities for the human experience. In realizing this, our long-term goal is to create humanity’s industrial base on Mars. The first step toward this long-term vision starts here on Earth – building rockets and pushing the boundaries of additive manufacturing.
