We read this from the posting text with AI. Skim the description below before ruling yourself out.
Why we read it this way (7)
This posting covers a wide band of levels (L1–L6), from Developmental (<3 years of experience) through Full Performance (3 YOE), Senior (6 YOE), Expert (11 YOE), Manager (16 YOE), and SME (16 YOE). Seniority is set to Mid as the floor/entry point for the range, but the actual hire level will vary significantly by candidate.
No specific named technologies, languages, or frameworks are required or mentioned anywhere in the posting — the JD describes responsibilities only in generic terms (enterprise web apps, databases, utility programs). The skills list therefore reflects only the broad functional areas stated as required duties.
Work location is not specified; the role supports an IC (Intelligence Community) program and requires an active TS/SCI with Polygraph, strongly implying an on-site requirement at a cleared facility. Remote is set to false accordingly.
Degree requirement is set to None because the JD explicitly allows professional experience to substitute for any degree level — no degree is a hard gate.
The alt SOC (15-1254 Web Developers) is noted because the JD explicitly calls out website design, development, deployment, maintenance, and QA of web sites; however, the broader enterprise application and database development duties make 15-1252 Software Developers the better primary fit.
Ignored 3 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): enterprise web application development, database design, website management.
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.
