Why we read it this way (6)
TS/SCI is a hard gate; the posting also states the candidate must be willing/able to obtain a TS/SCI with polygraph, implying the polygraph is a future requirement rather than a current gate.
Experience range spans 4–8 years (BS) or 2–6 years (Masters); the overall years minimum is set to 4, the lowest stated threshold. Relevant work experience is accepted in lieu of a degree, so the degree requirement is None.
The role has a meaningful security posture (STIGs, ACAS/Nessus, threat mitigation) that could support an Information Security Analyst classification, but the primary day-to-day duties — installation, configuration, administration, patching, AD management, virtualization — align more closely with Systems Administration (15-1244).
AWS Certified Cloud Practitioner and CompTIA AI appear under 'Preferred Qualifications' and are listed as certifications rather than demonstrated skills; both are marked preferred accordingly.
'CompTIA AI' appears to be a truncated certification name in the posting (likely 'CompTIA A+' or a newer AI-related cert); captured as written.
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.
