Electromechanical Actuator Engineer
Stoke Space
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.
Description
The electromechanical actuation systems are fundamental to the success of highly reusable, operable, and reliable space systems. As an Electromechanical Engineer at an early-stage start-up you will be responsible for designing, testing, and qualifying electro-mechanical actuators utilized for primary flight controls of the NOVA launch vehicle including Thrust Vector Control (TVC) and Engine Throttle Valve actuators.
You will work closely with the engines, fluids, avionics, and production teams to seek out state-of-the-art solutions to difficult problems, develop and own the company standards for actuator design, test them to their limits and iterate until making actuators one of our core competencies!
