Original 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:

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.

The Thermal team is responsible for predicting temperatures, designing thermal architectures, and guiding designs for the structures, fluids, components, and avionics of our launch vehicles. With a strong grasp of thermodynamics and all methods of heat transfer, the team addresses a vast number of thermal challenges across ground and flight phases. The team leverages first-principle hand calculations, reduced order modeling, and coupled system detailed thermal modeling to drive cross disciplinary vehicle designs. Our collaboration with hardware engineers and all other teams further enables us to overcome design and integration hurdles, ensuring a seamless and efficient development process from concept through launch.

About the Role:

Drive the architecture, sizing, and development of thermal systems like insulation, heaters, thermal protection, and environmental conditioning in collaboration with peer technical teams
Build, execute, and validate thermal analyses at the component, sub-system, and vehicle level, including supporting tool development and automation
Guide design and development engineers in the successful application of thermal sciences to achieve system and component requirements
Develop and execute tests to support thermal systems development and qualification, including test article integration, instrumentation setup, and data processing
Support vehicle and engine thermal system development and stage testing, as well as flight operations

About You:

Bachelor's degree in Engineering or related field
Experience in industry via internships or university collaborations
Strong fundamentals in heat transfer and thermal analysis
Hands-on experience with writing test plans and performing testing, instrumentation, and data analysis at the component and system level
Experience with an engineering scripting language like MATLAB or Python

Nice to haves, but not required:

Graduate degree in engineering or related field
Experience solving complex problems on integrated vehicles with design teams
Experience in component and system level thermal and fluids analysis, using relevant toolsets like Sinda/Fluint/Thermal Desktop or other commercial FEM/FDM/FVM solvers
Familiarity with cryogenic liquid rocket stage architecture, engine architecture, and operations
Understanding of aerodynamics and external flight related heating, including thermal protection system materials and thermal protection system sizing

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 - $136,000 USD

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.

If you need a reasonable accommodation, please contact us at accommodations@relativityspace.com.

Please note: Relativity Space does not accept unsolicited resumes, candidate profiles, or referrals from recruitment agencies or search firms. Any unsolicited submission - via email, our website, social media, or directly to an employee - will be deemed the property of Relativity Space, and no fee will be owed absent a current, fully executed agreement with Talent Acquisition that specifically authorizes submissions for the applicable role.
