Why we read it this way (8)
The role requires an active TS/SCI clearance with the ability to obtain a CI Poly as a hard gate; a CI Poly already in hand is listed under Desired Skills as a preferred differentiator.
The salary range quoted ($85,500–$150,765) applies specifically to Colorado (and several other named states); the posting notes the range may differ for other locations.
Nessus, Trellix, Splunk, ACAS, and SCAP appear together as illustrative examples within the required vulnerability/security management bullet — all are treated as hard gates on that capability cluster, not individually mandatory tools.
The 3+ years experience floor (Linux/Windows administration) is the stated minimum; 5+ years is listed under Desired Skills as a preferred differentiator.
Ansible and PowerShell are listed together under Desired Skills as interchangeable automation tool examples, so they are captured as a single preferred skill with alternatives.
RHCSA, MCSE, and CISSP are listed together under Desired Skills as alternative advanced certifications — captured as a single preferred skill with alternatives.
No degree requirement is stated anywhere in the posting.
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.
