Relativity Space is building Terran R, a next-generation rocket designed to deliver payloads to orbit using innovative 3D-printed manufacturing. The Structures and Mechanisms team owns the full design, build, and test lifecycle of integrated structures and flight mechanisms for the vehicle.
As a Senior Mechanisms Engineer, you will guide the design of critical flight systems including stage separation, payload deployment, aerodynamic control features, and landing gear. You'll work across the full engineering cycle—from conceptualization and trade studies through design, analysis, manufacturing, and testing. The role emphasizes hands-on hardware ownership, with direct visibility into how your designs come to life on the factory floor.
Key responsibilities include:
- Leading mechanism design for stage separation, fairing deployment, landing gear, and aero surface actuation systems
- Defining design criteria and subsystem requirements in collaboration with structures, avionics, and fluids teams
- Conducting trade studies on competing design concepts and presenting recommendations to leadership
- Reviewing static and dynamic load inputs, material properties, and manufacturing process constraints
- Leveraging Relativity's additive manufacturing process to unlock new design freedom and performance
- Supporting manufacturability refinements and production acceleration beyond first flight
You'll operate in a high-autonomy environment where technical rigor and creativity are equally valued. The team works on multiple subsystems rather than narrow specializations, giving you broad impact on vehicle architecture. This is an early-stage, high-momentum phase where your decisions directly shape both the product and the engineering culture.
