Manufacturing Engineer, Fluid Systems

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 seeking a Fluid Systems Manufacturing Engineer to join our team in Long Beach. Reporting to the Manager of Fluid Systems Manufacturing, this role will play a key part in developing the systems required for the design and build of the world’s first artificial-gravity, human-rated space stations.

This is a full-time, exempt position based in Long Beach, California.

Conceptualize, develop, and manufacture innovative tube-bending and welding cells to meet the demanding requirements of the Haven-1 program. Lead first-build and test efforts, including design integration, assembly sequencing, mBOM development, work order creation, and specification authoring.

Create and maintain detailed manufacturing plans, assembly procedures, and work instructions to ensure consistent, accurate production of all tubing systems.

Identify and resolve manufacturing challenges through root-cause analysis and implementation of corrective actions.

Apply critical thinking and problem-solving skills to challenge assumptions, push boundaries, and drive efficient human-spaceflight production within aggressive timelines.

Collaborate closely with design engineers, integration engineers, production teams, and external vendors to execute builds expediently and efficiently.

Develop efficient, capability-driven tooling solutions that streamline production, increase system output, and reduce operational burden.

Partner with quality assurance teams to establish and maintain rigorous quality control processes.

Establish and maintain standard practices, troubleshooting guides, and standardized repair procedures; review and approve all related planning documents.

Support day-to-day production of bent tubes, orbital tube welding (OTW), and manually welded tubing, ensuring optimal efficiency and adherence to quality standards.

Evaluate and challenge existing production and design requirements for tubing assemblies, using data-driven insights to eliminate waste and optimize the manufacturing process.

Continuously streamline and improve production systems by proactively identifying opportunities to enhance efficiency, reduce waste, and improve overall product quality.
