Why we read it this way (7)
Annapolis Junction, MD is within the Baltimore-Columbia-Towson CBSA (12580), close to NSA/Fort Meade — the TS/SCI with Polygraph requirement strongly implies an intelligence community customer.
The degree requirement is stated as 'Bachelor's degree + 11 years OR equivalent combination,' so no hard degree gate is set.
An alt SOC of 15-1212 (Information Security Analysts) is noted because a meaningful portion of the role involves RMF compliance, vulnerability management (IAVM, OpenVAS), firewall hardening, and security documentation (SSPs, STE/STN) — though day-to-day infrastructure operations is the primary framing.
OpenVAS, Prometheus, and Grafana are listed under 'Comfort with monitoring tools like…' — the 'like' qualifier suggests these are illustrative examples rather than strict gates, but they appear in the required qualifications block, so they are treated as required.
McAfee and UAM appear alongside RMF under 'Familiarity with' in the required block; 'familiarity' softens the language but the section placement keeps them as required.
Docker, MongoDB, Elasticsearch, Ansible, GitLab, RedHat Satellite, and software-defined networking are all listed under the explicit 'Nice to have' section.
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.
