How this req sits in the market our data
Most people in this occupation already list these. Still required — just not what gets you shortlisted.
What the occupation pays Median $101,310 (middle half $79,725–$129,425). This posting is about at that midpoint.
Estimated from BLS employment for this occupation and area, per-skill prevalence across our listing corpus, and published wage benchmarks — as of Aug 18, 2026. It is a model, not a headcount.
Why we read it this way (6)
The clearance requirement states 'DoD Secret or Top Secret' — either level satisfies the gate; Secret is the minimum and is reflected here.
Work location is not specified in the posting; no CBSA or state could be determined. The role is with a federal contractor and is unlikely to be fully remote given the clearance and STIG compliance context.
RHEL and Solaris are listed as parenthetical examples of Linux/UNIX experience; they are captured as alternatives under the Linux/UNIX requirement rather than as separate gates.
Shell scripting appears in both the responsibilities section (as a required activity) and the qualifications context; Perl appears alongside it in the maintenance scripting bullet and is treated as preferred since neither is called out as a standalone hard gate in the qualifications block.
The role sits between 15-1244 (systems administration) and 15-1212 (information security) given the dual emphasis on sysadmin duties and cybersecurity compliance/STIG work; 15-1244 is chosen as primary because the core day-to-day work is operating and maintaining infrastructure.
Requires a 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.
