CoreSite – Why Work For Us?

The core of who we are

CoreSite isn’t just another data center. 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.



Big enough to matter. Small enough to grow.

We’re 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. We’re a team of people from an assortment of experiences and cultures and skills, united under a common goal: powering a scalable community of costumer connections that matter. To everyone.


Enabling the digital economy

At CoreSite, our vision is to be at the core of IT transformation and propel the growth and performance of digital business. We’ve translated that into our critical mission of accelerating our customers’ growth and performance by delivering network-dense, cloud-enabled data center solutions and premium customer experiences to interconnected customer communities. All of this is supported by our key values: Simple, Honest, Strong. These values drive every interaction we have with each other, our customers, our prospects and our partners. We’re looking for people to join our team that will believe in that same mission, vision and values.

    Was invited to attend a hiring funtion at their Reston VA office and had scheduled an interview in June. Because of a current customer issue I was unable to make it and i called/emailed to ket them know. I followed up with my contact who is their director of hr to reschedule. After applying, writing and calling a few times there was no reply. I even offered to meet on a personal trip to Colorado to meet at theit HQ. Still no reply.
