Job description

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 Manufacturing Engineer, Environmental Control and Life Support Systems, reporting to the Senior Manager, ECLSS Manufacturing, to support the development, production, and integration of the systems required for human-rated space stations.

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

This role owns the fluid systems at the core of ECLSS: water, air, thermal, and pressurized gas hardware. You will define how new hardware is built the first time, prove it out through high pressure test and acceptance, and carry it into repeatable production across successive Haven modules.

Responsibilities:

• Own the manufacturing development, production readiness, and build execution of ECLSS fluid hardware for our artificial-gravity space station

• Develop, mature, and optimize manufacturing processes for ECLSS components and assemblies, from first builds through production and flight hardware

• Own the high pressure fluid test flow for assigned hardware, including proof, leak, and functional test planning, execution support, and data disposition

• Partner closely with design engineering to ensure hardware is manufacturable, reliable, inspectable, and scalable from early design trades through final production

• Create and maintain manufacturing plans, work instructions, assembly procedures, inspection plans, and production documentation

• Drive hands-on fabrication, assembly, integration, and test activities in a fast-paced hardware development environment

• Identify and resolve production issues through root cause analysis, failure investigation, corrective actions, and continuous improvement

• Lead design-for-manufacturing and design-for-assembly reviews internally and with suppliers

• Own manufacturing schedules, build sequencing, and production execution for assigned ECLSS hardware from early development through launch vehicle integration

• Work with technicians, quality, supply chain, design engineering, test engineering, avionics, software, and mission operations teams to ensure successful system integration

• Support supplier development and manufacturing readiness for externally produced components and assemblies

• Evaluate and implement manufacturing techniques for metallic, fluid, thermal, and soft-goods hardware, including machining, welding, brazing, tube bending, cleaning, bonding, and assembly

• Bring technical rigor, ownership, and continuous improvement to all aspects of manufacturing engineering

Additional Responsibilities at Staff Level:

• Set manufacturing strategy and standards across the ECLSS fluid hardware portfolio rather than a single subsystem

• Define and drive process, tooling, and inspection standardization across concurrent Haven module builds

• Serve as technical authority on manufacturing plans, build approaches, and high pressure test flows produced by other engineers

• Mentor and raise the technical level of Manufacturing Engineers I through Senior across the ECLSS team

• Own the manufacturing risk picture for ECLSS and drive risk reduction ahead of program milestones

• Represent ECLSS Manufacturing in program-level reviews and lead cross-organizational manufacturing initiatives

Minimum Qualifications:

• Bachelor's degree in an engineering or science discipline

• Senior Manufacturing Engineer: 5+ years of experience in manufacturing engineering, production engineering, or hardware development for fluid, thermal, environmental control, or life support systems

• Staff Manufacturing Engineer: 8+ years of the above, with demonstrated technical leadership across a subsystem, program, or team

• 3+ years of hands-on hardware experience supporting fabr
