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 System Architect, 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.

• Strong working knowledge of spacecraft subsystems and their interactions (power, thermal, life support, avionics, communications, structures)
• Excellent communication skills, with the ability to present complex technical trades clearly to executives, customers, and engineers

Preferred Skills & Experience:

• Strong systems-level intuition and experience in technical leadership roles on spacecraft, launch vehicles, or other mission- or safety-critical systems
• Experience working on lunar engineering programs
• Comprehensive understanding of one or more core engineering disciplines (Structures, Thermal, Avionics, Power, Flight Software, etc.)
• Demonstrated experience working with NASA or other government customers on technical requirements, deliverables, and reviews
• Hands-on experience with requirements and/or project management tools
• Experience leading design reviews (PDR, CDR) and verification campaigns
• Familiarity with NASA's Moon Base program, Artemis architecture, human-rating standards, and/or commercial partnership models
• Experience with crewed systems, habitats, or life support in extreme environments
• Experience in a fast-paced, hardware-rich startup environment with rapid design-build-test cycles
• Experience standing up new programs or teams from the ground up

Additional Requirements:

• Willingness to work evenings and/or weekends to support critical mission milestones
• Ability to travel up to 20% of the time to support customer meetings
