Harness Design 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 Harness Design Engineer, reporting to the Senior Manager, Harness Design to support the development of the systems that will be required for the design and manufacturing of artificial-gravity human-rated space stations. This will be a full-time, exempt position located in our Long Beach location.

Responsibilities

• Develop the electro-mechanical design of flight wire harnesses for the Haven space station.
• Develop the electro-mechanical design of development and test harnesses to support qualification testing efforts.
• Design and analyze complex electrical architectures and wire harness systems, including development of detailed wiring diagrams, connector layouts, and system integration documentation for multi-disciplinary spacecraft/vehicle electrical systems.
• Evaluate and implement power distribution and data communication strategies, ensuring proper signal integrity across mixed power/data pathways and selecting appropriate communication protocols ( Ethernet, RS-422, USB, etc.) for system requirements.
• Develop system logic and control architectures, creating interface control documents (ICDs) and performing electrical analysis to ensure compatibility between subsystems, including power budgeting, load analysis, and signal routing optimization
• Meet with multidisciplinary stakeholders to gather harness design objectives and requirements.
• Develop harness design and routing solutions with a 3D NX CAD environment.
