Windows System Administrator (TS/SCI) - COLSA Corporation

The MSIC/SCOAA Team is looking for a new teammate with a broad base in Windows (and hoping to find someone with cross-OS skills) that can support a mix of workstations and servers including both physical and virtual infrastructure as a mid-level Windows Systems Administrator in support of a highly dynamic, rapidly evolving environment.



A great candidate will already know how to securely deploy Windows, manage local and remote filesystems, and be able to collaborate with the team without significant oversight when resolving problems and completing tasks. An outstanding candidate will also have a Windows certification (like Microsoft Endpoint Administrator Associate), be able to use shell scripting and Python to automate tasks, understand and manage security features like firewalls and BitLocker, have experience with SCCM and/or Ansible, or have extensive Windows experience. Experience with Nutanix and Enterprise Storage (DDN, NetApp, SANs) would be a huge plus. If this sounds like you, apply today! I
