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. As a Guidance, Navigation, and Control (GNC) Engineer at an early-stage start-up, your work will span all aspects of GNC development for a reusable launch vehicle.

Your work will include algorithm development, simulation modeling, rigorous test, and support of launch operations. Your solutions will have a critical impact on the success of this organization and your work will be at the forefront of space technology. You must be ready to stay focused, move fast, self-direct, and learn on the fly.
