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 Demos 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 worlds 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. If you want to work with the most talented people on Earth furthering space exploration for humanity come join us.
Vast is seeking a Senior Power Engineer to own the power system architecture and development for a new constellation-ready 15kW spacecraft bus a product line designed to scale to hundreds of spacecraft per year.
This will be a full-time exempt position located in ourLong Beachlocation.
About the role:
Youll define the power system architecture for a 15kW-class spacecraft bus topology bus voltage battery sizing power electronics and fault protection. You own the architecture decisions the end-to-end power budget and the power quality requirements that payload customers must meet. Youll determine what needs to be built new versus what can be reused from heritage define requirements for any new avionics boxes and work with the electronics lead to get them built. Youll also coordinate with the solar array and battery teams on electrical performance and any modifications needed for this mission.
Responsibilities:
Define the power architecture DET vs MPPT topology bus voltage selection battery sizing solar array string configuration
Define requirements for power electronics boxes the electronics lead builds the boards you own what they need to do and how theyre tested
Own the power budget detailed by mode (safe nominal peak eclipse) closed with margin for all payload configurations including high-power compute payloads
Coordinate with the internal battery team assess whether the heritage battery meets this missions requirements and define any modifications needed
Coordinate with the solar array team on array electrical performance cell selection string voltage degradation articulation strategy
Own power distribution evaluate heritage options or define new requirements as the architecture demands
Define requirements for SADA and solar array release mechanism procurement
Define and tailor bus power quality requirements voltage regulation transient response inrush management EMI/EMC (tailored from MIL-STD-461 or equivalent) and work with payload customers to flow down and verify compliance
Own fault protection and safe mode power management undervoltage protection load shedding safe mode power profiles
Support system-level power trades how do high-power payloads affect battery sizing solar array sizing and eclipse performance
Contribute power budget and architecture trade results to the spacecraft design and simulation toolchain
Build a power engineering team as the program scales from first build to production rate
Minimum Qualifications:
Bachelors degree in Electrical Engineering Aerospace Engineering or a related technical discipline
6 years of spacecraft power system design experience solar array battery bus regulation power distribution
Experience with power architecture trades (DET vs MPPT bus voltage selection)
Power budget development and management across multiple operating modes
Battery management system experience charge control cell balancing state of charge estimation
Understanding of solar array electrical performance I-V curves temperature coefficients radiation degradation
Experience taking a power electronics box from requirements through functional test
Full lifecycle experience with spacecraft power systems requirements design build test flight and on-orbit operations
Able to obtain a security clearance
Experience with high-power spacecraft buses (5kW class)
SADA (solar array drive actuator) selection and integration experience
Power system experience across multi-satellite builds
Familiarity with LiIon battery electrochemistry and cell-level performance modeling
Fault protection and autonomous power management experience
Pay Range: California
$137760 - $195552 USD
