Vast•Long Beach, CA
•$137,000 - $230,000•Onsite

About The Position

Vast is seeking a Senior Power Systems Engineer to support development of the power systems required for its Lunar ecosystem. The Lunar program builds on technology, infrastructure, and experience from Vast’s Haven Demo, Haven-1, Haven Station, and Vast Satellite programs. The role owns power-system development from architecture through design, hardware bring-up, qualification, and integrated validation. It includes defining power architecture for lunar applications, designing and validating power electronics, addressing radiation, thermal, and dust challenges, and leading reliability and qualification activities. The engineer will also contribute to design reviews, mentor junior engineers, and help establish scalable design standards, component libraries, and processes across Vast programs. This is a full-time, exempt position based at Vast’s Long Beach, California location. The role reports to the Senior Vice President, Lunar Programs. Applicants should be willing to work evenings and/or weekends for critical mission milestones and travel up to 5% for customer meetings.

Requirements

  • Bachelor’s degree in Electrical Engineering.
  • At least 6 years of experience developing power electronics.
  • Demonstrated ownership of at least one power-electronics product from architecture through hardware bring-up and validation.
  • Willingness to work evenings and/or weekends to support critical mission milestones.
  • Ability to travel up to 5% of the time to support customer meetings.

Nice To Haves

  • Master’s degree in Electrical Engineering with a power-electronics emphasis.
  • Experience designing electronics for spaceflight and verifying workmanship and operability through environmental testing, including random vibration, shock, thermal testing, burn-in, and TVAC.
  • Experience with hardware intended for beyond-LEO, lunar, planetary, or other high-radiation and extreme-thermal environments, including radiation-tolerant part selection, derating, and screening.
  • Experience with human-rated or other high-consequence systems where fault tolerance and single-point-failure retirement drive architecture.
  • Professional experience with instrumentation and data acquisition.
  • Experience with programming languages or tools such as MATLAB, Python, or C/C++.
  • Experience with vehicle and instrumentation buses such as Ethernet, CAN, SPI, and I2C, and serial I/O such as RS422.
  • Experience with full-lifecycle product development, including transition to production and manufacturing support.

Responsibilities

  • Own power-system architecture, electronics specification, simulation, schematic capture, PCB and mechanical packaging design, board-level bring-up and validation, environmental qualification, and integrated system-level validation.
  • Define 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 for power conversion, load switching, hot-swapping, power conditioning, inrush control, and over-current fault detection, with appropriate margin for long-duration lunar surface and cislunar operation.
  • Lead radiation, thermal, and dust-mitigation considerations for power hardware operating beyond LEO, coordinating part selection, derating, and screening.
  • Perform failure modes and effects analyses and lead system-level reliability design and validation plans, including retirement of single-point failures for human-rated applications.
  • Own qualification campaigns end-to-end with test labs, including random vibration, shock, thermal cycling, burn-in, TVAC, and radiation testing.
  • Lead design reviews and present architecture, analysis, and test results to engineering leadership and cross-functional stakeholders at program milestones.
  • Mentor junior engineers, review designs, and help develop power-electronics design standards, component libraries, and processes that scale across Vast programs.

Benefits

  • Company equity for full-time employees.
  • Medical, dental, and vision coverage for employees and dependents.
  • Generous paid time off; exempt staff may receive 20+ vacation days and non-exempt staff may receive 10+ vacation days, with the ability to cash out unused vacation annually.
  • Paid parental leave.
  • Short- and long-term disability insurance.
  • Life insurance.
  • Access to a 401(k) retirement plan.
  • ClassPass credits.
  • Personalized mental healthcare through Spring Health.
  • Other discounts and perks.
  • Free snacks, drip coffee, cold drinks, and dinner meals; subsidized lunch.
  • Onsite barista.
