Office Coordinator and Administrative Assistant

Pacifico Energy develops, finances, builds, and operates energy infrastructure that powers businesses and communities. We work with hyperscalers, data center developers, and other large energy users to deliver reliable power tailored to their needs. Our U.S. team focuses on private grids and on-site generation that help customers bring projects online faster and reduce dependence on traditional grid connections. With projects across the United States, Japan, South Korea, and Vietnam, we bring global experience in solar, wind, battery storage, and natural gas to every stage of a project, from development and engineering through construction and operations.

We’re looking for an Office Coordinator & Administrative Assistant who enjoys bringing people together and making an office feel welcoming and run smoothly. You’ll join a close-knit, high-performing team in Dallas with a startup mindset: we move quickly, pitch in, and adapt as the business grows. 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.
