Why we read it this way (7)
The posting lists multiple work locations (Maryland, Virginia, Colorado, Texas, Utah, Florida, Hawaii) without specifying a primary site; Maryland is assumed as primary given the company headquarters (Constellation Technologies, cti-md.com).
The title is not stated in the posting; seniority is inferred from the 11-year experience requirement and the depth of technical scope.
TS/SCI with active polygraph is explicitly required — not merely preferred or a future requirement.
AWS and Red Hat Enterprise Linux appear only in the benefits/perks section as training resources, not as job requirements; listed as preferred for completeness.
Modeling experience and analytics development experience were omitted from the skills list as they name no specific technology or tool.
The alt SOC (15-1299) reflects the role's heavy focus on low-level/reverse-engineering work, which sits at the boundary of general software development and specialized computer occupations.
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.
