Why we read it this way (7)
The posting's primary work is operating and maintaining existing infrastructure (servers, network devices, AD, firewalls, VMware) rather than building new software or tooling, supporting 15-1244. However, the strong DoD security compliance and vulnerability/risk analysis duties create some overlap with 15-1212 Information Security Analysts.
Location is inferred as the Jacksonville, FL metro (Blount Island, FL is the primary site listed), with required travel to Parris Island, SC and Albany, GA.
Clearance: candidates with an active Secret clearance are acceptable at hire, but the role gates on the ability to obtain Top Secret/SCI — classified here as TopSecretSci accordingly.
Degree requirement: the posting explicitly accepts DoD/military technical training or 15 years of experience in lieu of a degree, so no minimum degree is hard-required.
Experience floor: the standard path requires 6 years; the no-degree path requires 15 years. The 6-year figure is used as the overall years minimum as it represents the minimum qualifying threshold.
IAT Level II, Microsoft Server/Windows, and Cisco certifications are listed as required but must be obtained within 6 months of hire — they are gates on continued employment rather than strict pre-hire screens, though they are listed under Basic Qualifications.
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.
