Our private grids bring dedicated generation and energy storage directly to customers, helping projects move forward without waiting for traditional utility connections. We draw on Pacifico Energy Group’s experience across the U.S., Japan, South Korea, and Vietnam, spanning solar, wind, battery storage, and natural gas.

We’re looking for an Office Coordinator & Administrative Assistant who enjoys bringing people together and making an office feel welcoming and run smoothly.

We work hard, celebrate our wins, and make time to have fun together.

You’ll help shape the everyday experience of our office, from a warm welcome at reception to thoughtful team events and a workspace people enjoy coming to. You’ll take ownership of office operations, coordinate moves and setup, and support our People team. If you enjoy getting to know people, spotting what needs doing, and bringing order to changing priorities, you’ll have plenty of room to make an impact. This is a full-time, on-site role based at reception. No travel is required.
