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 $132,021 (middle half $99,961–$167,095). 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 7, 2026. It is a model, not a headcount.
Why we read it this way (8)
The degree requirement is effectively 'None' because the posting explicitly accepts 9+ years of related experience in lieu of a Bachelor's degree.
NIST and ISO 27001 are listed together as a single requirement ('security frameworks and standards such as NIST, ISO 27001') under the required qualifications; they are captured as mutual alternatives on a single hard-gate skill.
ISSE CAP, ISSO, Security+, CISA, CASP+, MCSE, Linux, and CCNP certifications all appear under 'Qualifications We Prefer' and are therefore preferred.
Firewalls, intrusion detection systems, and antivirus software appear under 'Qualifications We Prefer' as a grouped example; antivirus software is a generic category rather than a named tool and is omitted per extraction rules.
NIST SP 800-53 (Rev 4/5), ACAS, and Elastic Stack (ELK) all appear under 'Qualifications We Prefer' and are therefore preferred.
The title 'Systems Security Engineer III' maps to a Senior-level individual contributor; the 'III' suffix and 5+ years required experience are consistent with Senior.
Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): NIST SP 800-53.
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.
