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.

As an Electric Propulsion Specialist, you'll work hands-on in the lab where our propulsion hardware gets built and tested. You'll work side by side with propulsion engineers to assemble, wire, and test electric propulsion hardware, from thrusters to the high-voltage power and harnessing that drives them.

• Fabricate, assemble, integrate, and test electric propulsion hardware, including thrusters, propellant feed components, power electronics, and test support equipment
• Build, inspect, and repair electrical harnesses and cable assemblies, including soldering, crimping, potting, splicing, lacing, and connector termination
• Safely work on high-voltage systems and equipment, following lockout/tagout, grounding, and other electrical safety practices
• Run, maintain, and troubleshoot vacuum chambers and pumping systems
• Set up and run thruster and component tests, including mounting hardware, routing instrumentation, checking out data acquisition systems, and monitoring tests
• Machine fixtures, brackets, adapters, and test hardware on manual and/or CNC mills and lathes from drawings or engineering sketches
• Diagnose electrical and mechanical problems using multimeters, hipot and insulation-resistance testers, oscilloscopes, and leak detectors
• Follow and help write work instructions, test procedures, and build travelers, and record as-built configurations and any non-conformances accurately
• Keep the lab, tooling, and test areas clean, organized, and safe, including inventory of consumables and spares
• Work with engineering, quality, and other technicians to feed manufacturing and test lessons back into design

• 5+ years of hands-on experience as an electrical, electromechanical, or test technician in aerospace, defense, research, or a similar high-reliability industry (or equivalent military experience)
• Demonstrated experience building wire harnesses and cable assemblies, including soldering, crimping, and connector termination
• Experience working safely on high-voltage systems or equipment
• Machining experience on manual and/or CNC mills and lathes

• Experience operating and maintaining high-vacuum…
