Systems Administrator III


CentralSquare Technologies | Cloud | Lake Mary, FL

The Applications Systems Administrator role is an intermediary between the purely infrastructure components and the purely application support roles. As such, the position includes responsibilities that touch both of these areas. Applications Systems Administrators routinely work hand in hand with Infrastructure, Product Support, Install, and Development.  A typical day may include application deployment, Operating System/Citrix/Network troubleshooting, Configuring Active Directory/Share/NTFS permissions, as well as Triage incoming issues for routing to the appropriate personnel.


As a level III administrator the candidate is expected to leverage technical expertise and strong communication skills to resolve escalated issues and to guide junior administrators.


This will require after-normal-business hours support, occasional weekend work, and will require being part of the technical 24/7 on-call rotation.  Availability to work a flexible schedule occasionally to meet customer and project needs is required.
