Why we read it this way (8)
Location is not specified in the posting; CACI notes the role 'can be worked in more than one location' and quotes a national average salary range. No CBSA could be determined.
The TS/SCI with Polygraph clearance is an explicit hard gate to start — candidates must hold an active clearance.
A Bachelor's degree is listed as required but the posting immediately qualifies it with 'or equivalent experience,' so no formal degree is treated as a hard requirement.
The SOC classification is Medium confidence: the role is primarily infrastructure operations (15-1244), but the heavy cybersecurity/IA compliance duties (Nessus, CyberArk, RSA, NISPOM, DCSA) create a genuine pull toward 15-1212 Information Security Analysts.
Microsoft Exchange, Jira, Confluence, Pure Storage, Dell PowerVault, RSA, and CyberArk appear in the responsibilities narrative rather than a formal required-qualifications block; they are marked preferred accordingly.
McAfee/Trellix are listed together as a single endpoint security solution; Nakivo and Commvault are listed as interchangeable backup options — each pair is captured as one skill with alternatives.
MECM and SCCM refer to the same Microsoft product (MECM is the current name); captured as one skill with SCCM as an alternative.
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.
