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.

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.

“The Most Successful Companies are the Ones that Employees Believe in.”

Each year, CoreSite participates in The Top Workplaces program, which recognizes good employers throughout 30 U.S. cities. The evaluations for this program are based purely on employee opinions, gathered through the WorkplaceDynamics survey. CoreSite has been chosen as a top workplace by our employees four out of the last five years – recognition that we believe speaks volumes about our culture.
