About the Role
You will have extreme ownership over all aspects of a component's design, analysis, manufacturing, testing, and validation for an advanced reusable rocket engine, including parts like thrust chambers, reentry heat shields, injectors, turbomachinery, actuators, and ignitors. You will be a key member of the engines development team, working through all phases of the product lifecycle. You will seek out state-of-the-art design and manufacturing techniques and tools to solve challenging problems, and you will continuously iterate and improve your designs. You must be ready to stay focused, move fast, self-direct, and learn on the fly.
