How this req sits in the market our data
Most people in this occupation already list these. Still required — just not what gets you shortlisted.
What the occupation pays Median $158,337 (middle half $126,441–$180,105).
Estimated from BLS employment for this occupation and area, per-skill prevalence across our listing corpus, and published wage benchmarks — as of Aug 3, 2026. It is a model, not a headcount.
Why we read it this way (7)
The experience requirement is stated as a sliding scale: 10 years with an advanced degree OR 15 years with a bachelor's degree. The 10-year minimum is used for the overall years minimum; the 15-year path is not separately representable in this schema.
The degree requirement is effectively None because the JD offers equivalent-experience paths at both levels rather than hard-gating on a specific degree.
Java, Python, and C# are listed as interchangeable options ('Java, Python, C#, or comparable object-oriented programming languages'); all three are captured as required with each other as alternatives.
RDF, OWL, and SPARQL appear in the responsibilities/duties section rather than the explicit Required Skills block, so they are marked preferred.
DevSecOps appears in the Required Skills section only as part of a familiarity/methodology phrase ('Familiarity with Agile software development methodologies, DevSecOps practices…'), which softens it to preferred.
An active TS/SCI with CI polygraph is a hard gate explicitly stated in both the opening and the Required Skills section.
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.
