About The Position

The Platform Engineering team is seeking a highly skilled Platform Administrator to support a hybrid infrastructure environment across both Windows and Linux platforms. This role requires strong hands-on experience with Windows Server OS and Red Hat Enterprise Linux (RHEL 8/9), with a heavy focus on deep OS-level troubleshooting and system performance analysis. The ideal candidate will be comfortable operating in a hybrid cloud and traditional datacenter environment, supporting critical systems and ensuring stability across platforms. This role will also be responsible for identifying, prioritizing, and remediating OS-level vulnerabilities, including applying security patches, responding to emerging CVEs, and ensuring systems remain compliant with enterprise security standards.

Note: Preference will be given to candidates in the vicinity of Chattanooga, TN.
