Power Electronics Engineer

Power Electronics EngineerVast 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 Power Electronics Engineer, reporting to the Manager, Power Electronics, to support the development of the systems that will be required for the design and build of artificial-gravity human-rated space stations.This will be a full-time, exempt position located in our Long Beach location.Responsibilities:End-to-end ownership of power electronics specification, architecture, simulation, schematic capture, PCB design, mechanical packaging design, board-level bring-up and validation, environmental qualification, and integrated system-level validation.Design circuits to implement functions such as power conversion, load switching, hot-swapping, power conditioning, inrush control, over-current fault detection, and more.Perform failure modes and effects analyses and drive reliability design and validation plans at the system level.Minimum Qualifications:Bachelor's degree in electrical engineering.2 years of experience in developing power electronics.Preferred Skills & Experience:Ability to creatively solve problems and bring multiple disciplines together while assessing risk and making design and development decisions with incomplete data set.Experience working in collegiate project teams (e.g. Formula SAE, Hybrid Electric Vehicle) and/or professional experience Professional experience with instrumentation and data acquisition (e.g. SPICE, SQL, and/or National Instruments hardware).Experience with software programming: Matlab, Python, C/C++, etc.Experience with vehicle and instrumentation buses such as Ethernet, CAN, SPI, and I2C, as well as serial I/O (RS232/422/485).Experience with full-lifecycle product development.Experience with designing electronics for spaceflight environment, verifying workmanship and operability through environmental test (random vibration, shock, thermal, burn-in, and TVAC).Strong sense of accountability and integrity with excellent written and verbal communication skills.Ability to thrive at an early-stage startup where you will have the opportunity to help create and optimize key systems and processes.Additional Requirements:Willingness to work overtime, or weekends to support critical mission milestones.Pay Range:Power Electronics Engineer II: $112,340-$159,468 Senior Power Electronics Engineer: $137,760-$195,552Pay Range: California$112,340 - $195,552 USDWe calibrate level and compensation to the selected candidate's experience and demonstrated capability.
