Why we read it this way (6)
The posting requires an active TS/SCI with Full Scope Polygraph — this is a hard gate explicitly stated at the top of the description.
MySQL, PHP, Windows Server, REST API development, and Microsoft SQL Server administration all appear under the primary 'Key Responsibilities' / required skills block, framed with 'Familiarity with' — the substitution qualifier softens the specific tool but not the requirement itself, so they are treated as hard gates.
The SOC is a close call between 15-1252 (Software Developers) and 15-1211 (Computer Systems Analysts); the role's primary deliverables are building and extending ServiceNow applications using JavaScript, which tips it toward software development.
The 'Highly Desired Qualifications' section is explicitly labeled as 'not mandatory,' so all skills drawn from it are marked preferred.
The compensation range ($130,000–$260,000/year) is unusually wide, likely reflecting a broad band across clearance levels or seniority tiers within the firm.
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.
