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. Highly efficient and extremely reliable rocket engines will make these reusable delivery systems a reality. As an Engine Assembly Technician you will be responsible for the precise and rapid building of a variety of engine components including (but not limited to) turbo machinery, injectors, thrust chambers, pressurized tube connections, and valves.

Leveraging your previous experience, you will both build assemblies alongside engineers and independently; all while giving design feedback and logging accurate build notes for future reference. You will use your resourcefulness and communication skills to identify and solve issues with the assistance of machinists and welders. You will be responsible for maintaining an efficient work area, including ownership of its layout, tooling, and local inventory storage. You must be ready to stay focused, move fast, self-direct, and learn on the fly.
