Why we read it this way (8)
No work location or CBSA is specified in the posting. Given the TS/SCI with Full Scope Polygraph requirement, the role is almost certainly on-site at a cleared facility, but the specific location is not disclosed.
The SOC classification is a judgement call: the role blends security analysis (15-1212) with systems/security engineering. 15-1299 (Computer Occupations, All Other) is noted as a runner-up because 'Information System Security Engineer' is a distinct engineering discipline that doesn't map perfectly to the analyst SOC, but 15-1212 is the closest available code for the primary day-to-day work described.
NIST SP 800-37 (RMF), DIACAP, NIACAP, and DCID 6/3 are listed together as interchangeable framework options under the required qualifications; they are captured as a single skill with alternatives accordingly.
DITSCAP is listed in the responsibilities section (not the requirements block) as a documentation guideline, but given its specificity and centrality to the described duties it is included as a required skill.
Cloud platforms (AWS, Azure, GCP), DevSecOps, Databricks, GitLab, and Jira all appear under 'Desired Experience' and are marked preferred.
CISSP, ISSEP, and CISM are professional certifications listed under 'Desired Experience' and are marked preferred.
Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): Security Test and Evaluation (ST&E).
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.
