Electric Propulsion Specialist

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.

• Experience operating and maintaining high-vacuum systems, including roughing pumps, turbomolecular pumps, diffusion pumps, and/or cryopumps

• Experience with helium leak detection, vacuum gauges, and vacuum fittings (KF, CF, ISO)

• Experience with electric propulsion systems (Hall-effect, gridded ion, or similar) or plasma/high-voltage lab equipment

• Welding experience (TIG preferred), especially on stainless steel or thin-walled tubing

• Current IPC/WHMA-A-620, J-STD-001 (including Space Addendum), and/or NASA-STD-8739 certification

• Experience with precision cleaning, cleanroom work, or contamination control for flight hardware

• Experience with propellant feed systems, including tube bending, fittings, and pressure/leak testing

• Ability to read and interpret electrical schematics, wiring diagrams, and mechanical drawings, including GD&T

• Experience with data acquisition systems and test instrumentation

• Familiarity with documenting work in an MES or similar system for manufacturing and quality records

• Strong attention to detail and a commitment to quality and safety

• Ability to work effectively in a team and to make sound independent judgments with limited information
