The Core of Who We Are

CoreSite isn’t just another data center company. It’s a mission. We’re committed to connection through the power of community, and our team reflects that vision. A career at CoreSite means helping to leverage the power of technologies that make the world spin. See below what makes CoreSite one of the top places to work.

United in a Common Goal

CoreSite is a company big enough to make a difference in the global economy of technology, but small enough that each member of our team can have an impact.

We’re not a monolithic collection of silos, or a company that treats employees like a number. We’re a team of people from an assortment of experiences, cultures and skills, working together to power a scalable community of customer connections.
