Job description

Company Overview

At Vast, our mission is to contribute to a future where billions of people are living and thriving in space. Vast is developing next‑generation space stations 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. Using an incremental, hardware‑rich and low‑cost approach, Vast is rapidly developing its multi‑module Haven Station. 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, followed by additional Haven modules to enable permanent human presence by 2030. Our team is all‑in, committed to executing our mission safely and on time.
