Solar Array Engineer, Mechanical

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 Solar Array Engineer, Mechanical, reporting to the Principal Power Systems Engineer, to support the design, analysis, build, and test of mechanisms for solar array deployment and articulation on human-rated space stations.

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

Responsibilities: 

• Design and analyze mechanisms for solar array deployment, including spring-driven hinges, latches, dampers, and hold-down/release devices
• Design and analyze mechanisms for solar array articulation, including motorized gimbals, gear trains, bearings, and drive electronics interfaces
• Build and maintain torque budgets for deployment and articulation mechanisms, including friction, harness resistance, disturbance torques, and margin verification per NASA-STD-5017B
• Select and specify bearings, lubricants, motors, gearboxes, encoders/resolvers, and other drivetrain components for the space environment
• Perform or support mechanism life analysis — bearing life, lubricant life, wear analysis — and define qualification test programs to demonstrate life margin
• Design for integration and test — develop deployment test procedures, gravity offload approaches, and workmanship screens
