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 the fluid/thermal analyst at Stoke, you will own all aspects of thermal system design, analysis, testing, and validation for a reusable launch vehicle. You will work closely with the vehicle design and manufacturing team through all phases of the product lifecycle. You will seek out state-of-the-art analysis techniques and tools and you will develop company standards for analysis methods. As part of a small, well-supported team, you will have access to the resources you need to get the job done right while simultaneously boosting your skills at a pace that can’t be matched in most other roles. You must be ready to stay focused, move fast, self-direct, and learn on the fly.
