Requirements

Review of static and dynamic load inputs, material properties & manufacturing process

Conduct trade studies on different mechanism design concepts and present to leadership

Your mission will be to deliver on time and budget.

You will be challenged to integrate as many subsystems within our printed primary structure, and support the development of our additive process to make this a reality.

To achieve this, you will be working closely with our vehicle design, test and loads teams, as well as our additive and manufacturing teams.

5+ years of experience in a full cycle design engineering role, including CAD, analysis, build and test

Responsibilities

To support our mission of changing the way rockets are built and flown, you will guide the design of Terran R mechanisms such as stage separation, payload deployment, aero control features and landing gear.

To be successful, you will be working collaboratively with partner groups such as structures, avionics and fluids; and leverage our additive process and design freedom to design and build better products.

The scope of work encompasses a full design cycle, including conceptualization, trade studies, design, analysis, manufacturing and testing of components.

Design and test the Terran R stage separation or fairing deployment system

Innovative conceptualization of the Terran R landing gear or aero surfaces actuation

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.
