Senior Power Systems Engineer, Lunar

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 Power Systems 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.

This will be a full-time, exempt position located in our Long Beach location. Responsibilities:
End-to-end ownership of power system architecture, electronics specification, simulation, schematic capture, PCB design, mechanical packaging design, board-level bring-up and validation, environmental qualification, and integrated system-level validation

Define and own power architecture tradeoffs for lunar applications - including energy storage integration, solar array interfaces, eclipse and survival-mode power budgets, and fault-tolerant distribution topologies

Design circuits to implement functions such as power conversion, load switching, hot-swapping, power conditioning, inrush control, over-current fault detection, and more, with margin appropriate to long-duration lunar surface and cislunar operation

Lead radiation, thermal, and dust-mitigation design considerations for power hardware operating beyond LEO, coordinating part selection, derating, and screening

Perform failure modes and effects analyses and drive reliability design and validation plans at the system level, including single-point-failure retirement for human-rated applications

Own qualification campaigns end-to-end, partnering with the test lab across random vibration, shock, thermal cycling, burn-in, TVAC, and radiation testing

Drive design reviews and present architecture, analysis, and test results to engineering leadership and cross-functional stakeholders at key program milestones

Mentor junior engineers, review their designs, and help build the power electronics design standards, component libraries, and processes that scale across Vast programs

Minimum Qualifications:

Bachelor's degree in Electrical Engineering6+ years of experience developing power electronics

Demonstrated ownership of at least one power electronics product from architecture through hardware bring-up and validation
