Why we read it this way (7)
The role is titled 'Linux System Administrator' with no seniority level in the title; however, the scope — complex scripting, cross-domain solution sustainment, SLA management, incident response, and broad latitude in methodology — supports a Senior-level assessment.
TS/SCI with CI Polygraph is explicitly required ('TS/SCI with CI Poly Needed!'), gating the role.
Red Hat Linux 7/8/9, Ansible, Git, Docker, Python, and Bash are listed under 'Top Skills' — a primary skills block in the posting — and are treated as hard gates alongside the general Linux administration requirement stated in the 'Skills' section.
VMware ESXi and Proxmox appear together as interchangeable virtualization platform options under 'Top Skills' with the qualifier 'such as'; VMware ESXi is listed as the primary with Proxmox as an alternative.
SNMP monitoring appears in the role narrative as an additional task rather than in a formal requirements block, so it is marked preferred.
The role has a meaningful scripting/development component (Python, Bash, potential software development, sensor development), which creates some ambiguity with 15-1252 Software Developers; however, the primary framing is system administration and operations, supporting 15-1244.
Requires a TS/SCI clearance — the cleared population is a small fraction of this occupation, so the real candidate pool is materially smaller than the estimate below, which does not model clearance.
