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.
