- Review of static & dynamic load inputs, material properties & test as well as structural systems & subsystems requirements
- Analysis and sizing of flight structures to ensure timely design reviews and drawing release
- Develop and support hardware test campaigns, including test integration, operation and result evaluation
- Support manufacturing process development
In order to be successful in this role, you must be someone who is self-motivated, adaptable and is able to lead your own projects to completion in a fast-paced environment. Ideally, you have significant mechanical or structural design experience and a proven track record completing collaborative projects effectively.
On a weekly basis, you will be designing flight components for our upcoming Terran R vehicle using NX/TeamCenter, performing analysis using Nastran, ANSYS and/or hand calculations, creating and releasing drawings as well as supporting fabrication of your components. You will own your design from requirements to production. You will also use your strong organizational skills to properly document your work and present your recommendations when decisions are needed.

About Relativity Space
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
The Structures and Mechanisms team is responsible for the full design, build, and test lifecycle of Terran R's integrated structures and flight mechanisms. Whether you're working on highly iterative mechanisms that move or tight-margin structures that shouldn't, you'll get hands-on hardware ownership and see the rocket coming to life on the factory floor.
Both teams fall under one department, sharing design principles, tools, and an integrated approach that provides a comprehensive view of Terran R. Team members work on multiple parts, not just within a single subsystem, and are empowered to make decisions that directly impact flight hardware. Beyond first flight, you'll play a critical role in refining for manufacturability and speed.
