Systems - Thermal Fluids Analyst

At Stoke, we believe that a thriving space economy leads to a vibrant, sustainable, and equitable future here on Earth. That is why we are building our fully and rapidly reusable vehicle, Nova. It is designed to fly daily and solve the core challenges of space transportation – it reduces cost, increases availability, and enhances reliability. By radically lowering the cost and increasing the cadence of launch, we’re able to create a truly scalable space industry.

Our team is mission-driven, collaborative, and empowered with ownership of their work. If you want to work with some of the most dedicated and talented people on Earth, come join us.

Reusable launch systems are the key to seamlessly connecting Earth and space. As a Thermal-Fluids Analyst at Stoke, you will be responsible for developing both detailed and system level thermal and fluids models that provide key insights into the performance of our critical systems. This role will have the opportunity to directly impact how we architect, design and operate our vehicles through analysis work performed.

You will work closely with other engineers throughout Stoke to accomplish these objectives. 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.
