A thriving economy in space is needed to make life on Earth more vibrant, sustainable, and equitable. Space technology will enable global access to information, solutions to climate change, answers to global food security, products that transform healthcare, clean energy production, and more. Today, rocket launch options are slow, expensive, and unreliable. Stoke is building the world’s most efficient fully and rapidly reusable rocket designed to fly daily that will radically increase access to space and open up the space economy to safeguard our precious home, Earth. Reusable systems are the key to seamlessly connecting Earth and space. Stoke’s 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.
