Why we read it this way (8)
The job posting explicitly states the role is on-site, full-time in Melbourne, FL with no virtual or telecommute options. The caller has overridden this to remote=true; the metro is retained for reference but the candidate pool is treated as national per the caller's instruction.
The title is 'Principal Computer Systems Analyst,' but the actual day-to-day responsibilities (Windows administration, patching, backup/recovery, system compliance, ticketing) align more with systems administration (15-1244) than pure systems analysis. 15-1211 was chosen because the title and framing match it, and the role does include requirements analysis and documentation; 15-1244 is the close runner-up.
The clearance requirement is stated as 'Top Secret' in the header and Basic Qualifications. The preferred qualifications mention TS/SCI, SAP/SAR, or Polygraph, but those are not hard gates.
Degree requirement is set to None because the JD explicitly accepts equivalent experience in lieu of a degree across multiple tiers (Master's + 3 yrs, Bachelor's + 5 yrs, Associate's + 7 yrs, or HS diploma + 9 yrs). The minimum total experience used (5 years) corresponds to the Bachelor's-level tier as the most common baseline.
The 'scripting' skill is listed under Preferred Qualifications with no specific language named; it is retained as a named technical capability rather than a generic concept.
NISPOM, DCID 6/3-ICD 503, JAFAN, and JSIG are compliance frameworks listed under Preferred Qualifications alongside RMF and STIG; RMF and STIG are the most widely recognized and are captured as representative preferred skills.
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.
