Engines - Propulsion Engineer

Description

Reusable systems are the key to seamlessly connecting Earth and space. Stokes Engines Team is developing reusable LNG/LOX full-flow staged combustion first stage engines and a LH2/LOX expander second stage engine for our launch vehicle Nova. As an Engines Propulsion Engineer you will have extreme ownership over all aspects of a components design analysis manufacturing testing and validation for an advanced reusable rocket engine (components like engine layouts thrust chambers reentry heat shields injectors turbomachinery actuators ignitors etc). You will be a key member of 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.
