Propulsion Structures Engineer

Vast is developing next-generation space stations and space infrastructure using an incremental, hardware-rich, and capital-efficient approach. Vast is rapidly developing its multi-module Haven Station to support a continuous human presence in space for America and its allies, enabling advanced microgravity research and manufacturing, and supporting a growing space economy for government, corporate, and private customers. Haven Demo’s 2025 success made Vast the only operational commercial space station company to design, build, and operate its own spacecraft in orbit. Next, Haven-1 is targeted to become the world’s first commercial space station, with launch anticipated in 2027, followed by additional Haven modules. Additionally, the company recently announced two new offerings leveraging its space station components and the heritage of Haven Demo: Vast Satellite, a high-power satellite product line; and Vast Lunar Systems, power, communications, and habitats for the Moon.

Headquartered in Long Beach, California, and with more than 1,000 employees and over a billion dollars in private capital, Vast has built the facilities capable of manufacturing America’s next space station. The company plans to develop future habitats and systems for Mars, dedicated modules for government partners, and other crewed systems designed to unlock the expanding long-term space economy.
