At Vast, our mission is to contribute to a future where billions of people are living and thriving in space. Vast is developing next-generation space stations 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. Using an incremental, hardware-rich and low-cost approach, Vast is rapidly developing its multi-module Haven Station.

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, followed by additional Haven modules to enable permanent human presence by 2030. Our team is all-in, committed to executing our mission safely and on time.

Manager of Design Reliability , to guide the design, verification, and validation of Haven-1, the world's first commercial human-rated space station. As a Thermal Fluids Design Reliability Engineer, you will ensure thermal fluids systems on Haven-1 are appropriately designed and function reliably, without failure, over their intended lifespan by integrating reliability principles directly into the design process. You will drive Failure Modes and Effects Analysis (FMEA), guide test plan definition and review verification validation data, and facilitate design teams to prevent failures before manufacturing.

You will work closely with hardware teams to ensure build practices meet design intent, define test methodologies, and analyze field data to improve design robustness. You will be responsible for shepherding the Haven-1 thermal, environmental control, and life support systems through detailed design and transitioning the space station from design, to a built and tested station ready to host humans in space. This will be a full-time , exempt position located in our Long Beach location.

Technical Leadership: Guide design of thermal, environmental control, and life support systems on a large scale space station. Cultivate Vast's understanding of thermal and fluids analysis considerations to drive design decisions. Lead the technical reviews providing clear, decisive guidance of mechanical design and analysis, manufacturing drawings, test plans, concept of operations, during milestone design reviews and major risk gates.
