Job description

Vast is developing next-generation space stations and space infrastructure using an incremental, hardware-rich, and capital-efficient approach. Vast is rapidly developing its multi-module Haven Station to support a continuous human presence in space for America and its allies, enabling advanced microgravity research and manufacturing, and supporting a growing space economy for government, corporate, and private customers. Haven Demo’s 2025 success made Vast the only operational commercial space station company to design, build, and operate its own spacecraft in orbit. Next, Haven-1 is targeted to become the world’s first commercial space station, with launch anticipated in 2027, followed by additional Haven modules. Additionally, the company recently announced two new offerings leveraging its space station components and the heritage of Haven Demo: Vast Satellite, a high-power satellite product line; and Vast Lunar Systems, power, communications, and habitats for the Moon.

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 capable of manufacturing America’s next space station. The company plans to develop future habitats and systems for Mars, dedicated modules for government partners, and other crewed systems designed to unlock the expanding long-term space economy.

Vast is looking for a Senior Mechanical Engineer, Lunar, reporting to the Senior Vice President, Lunar Programs, to support the development of the systems that will be required for Vast’s Lunar ecosystem. Our team is applying the technology, infrastructure, and knowledge built across our Haven Demo, Haven-1, Haven Station, and Vast Satellite programs to a new frontier: the Moon. Our Lunar program isn't starting from scratch, giving this founding team an extraordinary running start to help shape humanity's next era of lunar exploration from day one.

As one of the earliest Mechanical Engineers on the Lunar team, you'll play an outsized part in developing Vast’s lunar ecosystem. In this role you will have the opportunity to cover a wide range of components and systems for the Moon. You will concept, design, build, and test engineered systems that require an understanding of mechanical design, power systems, fluid systems, mechanisms, and materials engineering. The ideal candidate will be a full-ownership responsible engineer with broad knowledge that can take a product from beginning to end.

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

Responsibilities:

• Own end-to-end lunar engineering projects such as solar and battery power stations, gas and fluids consumables pallets, airlocks, nodes, habitation modules, hatches, and docking systems.

• Lead trade studies on lunar designs, interfacing with power, thermal, avionics, life support, and industrial design teams

• Work with lunar subject matter experts and systems architects to bring lunar concepts to reality that mesh with Vast’s larger lunar ecosystem and NASA’s Moon Base architecture

• Develop and maintain CAD models (NX or equivalent), flowing design intent through to fabrication and release

• Drive fabrication, assembly, and integration of hardware, partnering with manufacturing and integration teams on design-for-manufacturing

• Lead hardware bring-up, checkout, and anomaly resolution

• Represent your systems at design reviews and program milestones

Minimum Qualifications:

• Minimum of a B.S. in aerospace engineering, mechanical engineering, electrical engineering, materials engineering, mathematics, physics, or related technical discipline

• 6+ years of experience in mechanical design for space applications, with direct ownership of hardware from design through test

• Hands-on CAD proficiency (NX or equivalent) with experience taking mechanical/electromechanical/fluids designs from concept through flight release

• Demonstrated experience owning a hardware subsystem end-to-end (design, build, integration, and test), not solely in an analysis or support capacity

• Ability to read and interpret engineering drawings, fluid schematics, and electrical circuit diagrams

• Excellent written, verbal, and interpersonal skills, and ability to communicate technical information to non-technical partners

Preferred Skills & Experience:

• Experience working on lunar engineering programs.

• Experience designing or delivering deployable spacecraft structures (solar arrays, booms, masts, or similar mechanisms)

• Experience with battery system design, sizing, or qualification for space applications

• Familiarity with the lunar surface or deep-space thermal, radiation, and solar environment (or equivalent extreme-environment design experience)

• Experience leading hardware through formal verification campaigns (functional, environmental, vibration, thermal-vacuum)

• Prior experience in a fast-paced commercial space or startup hardware environment, comfortab
