Mechanisms Engineer

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 Mechanisms Engineer, reporting to the Sr. Manager of Mechanisms, to support the development of space mechanisms.

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

• Develop mechanisms from ideation to flight: design, analyze, build, test, and iteration. Some mechanisms include motorized assemblies, linkages, spring/damper systems, rotating hardware, and crew-operated assemblies

• Own critical spacecraft hardware/systems, assuming profound responsibility for their hardware

• Interface with a world-class production team to ensure successful translation of designs into spacecraft

• Bachelor's degree in mechanical, electrical, aerospace, or similar engineering

• 2+ years of experience in the design, build, and/or test of mechanisms, structures, valves, or other mechanical systems

• Thriving in a team that emphasizes rapid prototyping, quick iteration, and a general bias towards action

• Strong understanding of spacecraft and/or launch vehicle mechanisms and mechanical assemblies

• Experience in NX/Teamcenter or other CAD packages (PTC Creo, CATIA) with a solid understanding and application of geometric dimensioning and tolerancing (GD&T) per ASME Y14.5

• Professional or project experience with FEMAP, ANSYS, or similar finite element analysis (FEA) software tools, as well as a good understanding of fatigue, fracture, and crack propagation

• Knowledge of metallic manufacturing techniques, processes, equipment, and other processes such as machining, welding, riveting, bending, assembling, etc.

• Good understanding and experience working with aerospace materials (metals, plastics, composites)

• Solid understanding of test methods/setups and data acquisition systems

• Ability to perform trade studies using first principles and engineering fundamentals to make clear recommendations even with partial information

• Passion for advancing the commercial space industry and human spaceflight

• Able to work well in an integrated collaborative team environment, including frequent interactions with
