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 $128,188 (middle half $100,819–$156,589).
Estimated from BLS employment for this occupation and area, per-skill prevalence across our listing corpus, and published wage benchmarks — as of Jul 28, 2026. It is a model, not a headcount.
Why we read it this way (6)
The experience requirement is a dual path: High School Diploma/GED with 7+ years OR a B.S. degree with 3+ years of RHEL systems administration experience. The overall years minimum is set to 3 (the lower bound of the degree path); the 7-year path without a degree is the alternative.
An active IAT Level II certification (e.g., CompTIA Security+, CySA+, CCNA Security) is explicitly required but names no single product, so it is captured here in notes rather than as a named technology skill.
Cameo NoMagic is listed under Minimum Qualifications as 'knowledge of' — this is a softer gate than most required skills, but its placement in the required section warrants treating it as a hard requirement.
Bash/Python/Perl scripting and Ansible/Puppet configuration management are listed under Preferred Qualifications and are marked accordingly.
Both Warrenton, VA and Fort Washington, MD are within the Washington-Arlington-Alexandria DC-VA-MD-WV CBSA.
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.
