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 team at Relativity is responsible for the successful development of the engines that will power the Terran R vehicle. We own their design from concept through to launch and reuse. Our team partners heavily with manufacturing, test, launch, and integration teams, striving to develop our engines in record time and to support Terran R’s first launch in 2026. As part of this team, you will help build, test, and iterate on the full product lifecycle of our Aeon-R engine systems, seeing them mature and eventually bring Terran R into space.

About the Role:

Responsible for the thermal, structural, dynamic, and durability (fatigue/fracture) analyses on Aeon-R engines to guide design decisions and ensure reliability and performance requirements are met
Responsible for the analysis of 3D-printed engine components, complex mechanical assemblies, and/or the structural integrity of the fully integrated engine assembly
Work hand-in-hand with mechanical designers and manufacturing engineers to arrive at optimal solutions for the engine and vehicle programs
Develop and execute tests to support development and qualification, including hands-on work like test article integration, instrumentation setup, and data processing

About You:

Bachelor’s degree in a science, engineering, technology, or mathematics field
5+ years of relevant analysis experience, preferably with complex engineering systems
Experience with Finite Element Analysis
Experience with computer aided design (CAD) software

Nice to haves, but not required:

Detail-oriented, organized, and able to follow through
Strong drive to deliver on ambitious schedules
Experience with design of liquid propulsion components and systems
Experience with Siemens NX, Teamcenter, and ANSYS workbench
Familiarity with industry best practices
Familiarity with aerospace standards
