Vast is rapidly developing its multi-module Haven Station to ensure a continuous human presence in space for America and its allies, enabling advanced microgravity research and manufacturing, and unlocking a new space economy for government, corporate, and private customers. Haven Demo’s 2025 success made Vast the only operational commercial space station company to fly and operate its own spacecraft. Next, Haven-1 is expected to become the world’s first commercial space station when it launches in 2027, followed by additional Haven modules. Additionally, the company recently announced Vast Satellite, a high-power satellite product line leveraging its space station components and the heritage of Haven Demo.\nHeadquartered inLong Beach, California, and with more than 1,000 employees and over a billion dollars in private capital, Vast has built the facilities required to manufacture and operate America’s next space station. The company plans to develop future habitats and systems for the Moon and Mars, dedicated space stations for government partners, and other crewed systems that will unlock the expanding long-term space economy.\nVast is looking for a Fluid Systems Engineer to support the design, development, manufacturing, and integration of fluid systems across our space station and spacecraft programs. Our fluid systems span environmental and thermal control (ECLSS/TCS), pressurized gas and propellant systems, electric propulsion feed systems, and ground support equipment - all of which are absolutely critical to the safety, performance, and reliability of our crew and spacecraft.\nAs a Fluid Systems Engineer at Vast, you will work hands-on alongside technicians, manufacturing engineers, and cross-functional teams to bring fluid systems to life in a fast-paced, high-ownership environment.
