How this req sits in the market our data

Estimated from BLS employment for this occupation and area, per-skill prevalence across our listing corpus, and published wage benchmarks — as of Jul 29, 2026. It is a model, not a headcount.
Why we read it this way (9)
Location is inferred as the Nevada Test and Training Range area (Nellis AFB / Las Vegas metro) based on JT4's known J-Tech II contract footprint; the posting does not explicitly name a city.
The posting titles the role 'Systems Administrator II' with no seniority modifier, but the 5-year experience requirement and scope of duties (independent work, COMSEC oversight, cross-functional responsibilities) support a Mid-level classification.
The degree requirement states 'Associates or higher … or equivalent academic/technical training,' which means equivalent experience is accepted in lieu of a degree — no minimum degree is hard-gated.
CompTIA Security+ (DoD IAM Level II) must be obtained within 180 days of hire; it is treated as a hard requirement because failure to obtain it affects continued employment.
The COMSEC duties and Special Access Program (SAP/SAPF) support give this role a meaningful security-analysis dimension, making 15-1212 a plausible alternative SOC; however, the primary day-to-day work described is systems/network administration and IT operations.
CAD/CAM experience is listed under the required qualifications section alongside Windows Server and MS Office, so it is captured as a hard requirement despite being an unusual pairing for a sysadmin role.
The posting mentions 2nd shift and some weekend work may be required.
Ignored 2 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): LAN administration, web page development.
Requires a Top Secret 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.
