Position Overview:

We are seeking a Senior Linux Systems Administrator for our headquarters in Madison, WI. While this role has a wide variety of duties, the primary responsibility will be provisioning and maintaining various Linux based servers and other infrastructure across our headquarters in Madison, as well as our 3 U.S. offices and 2 branch offices abroad.

The Senior Linux Systems Administrator will be joining a team of four other system administrators, including the IT Manager, to whom this position will report. All IT personnel are located in the Madison office, and we’re looking for a candidate who will hit the ground running, fully supported by your fellow system admins in a team atmosphere.
