Sr. Valves and Actuator Engineer

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.

Stoke’s Valves and Actuators team is responsible for designing, developing, testing and producing various in-house and purchased valves and actuators for use on our launch vehicle, Nova. As a team, we strive to make designs that are both reliable and easily manufacturable, a goal supported by Stoke's commitment to developing in-house valve and actuator manufacturing for rapid iteration and self-sustainability. Our components are used in a variety of applications, including but not limited to engine flow control valves, large propellant valves, high-pressure gas valves, throttle valve actuators, and engine gimbal TVC actuators.

As a Sr. Valves and Actuators Engineer, you will be responsible for defining, designing, manufacturing, testing, and qualifying various valve designs for both the stages and engines. As a responsible engineer, you will be owner of the entire process for your designs. 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.
