The posting

Vast is developing next-generation space stations and space infrastructure using an incremental, hardware-rich, and low-cost approach. 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.

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 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.

Vast is looking for a Senior IT System Administrator, reporting to the System Administrator Manager, to support the development of the systems that will be required for the design and build of human-rated space stations.

As a Senior IT System Administrator, you will be responsible for the management, support, and enhancement of the IT infrastructure, IT service delivery, and end-user IT experience. This role ensures the reliable operation and performance of our IT infrastructure and solutions for the site and beyond, playing a pivotal role in managing and overseeing IT systems. You will install and maintain user endpoint devices and support infrastructure managed by other IT teams while training users on complex systems and computer functions.

This will be a full-time, exempt position located in our Long Beach location.

Why it works

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
