Estimated from BLS employment for this occupation and area, per-skill prevalence across our listing corpus, and published wage benchmarks — as of Jul 28, 2026. It is a model, not a headcount.
Why we read it this way (8)
The role is described as a blend of data science and systems engineering; 15-2051 (Data Scientists) was chosen as primary given the emphasis on data modeling, algorithms, graph databases, and analytics, with 15-1211 (Computer Systems Analysts) as a close runner-up given the systems engineering, requirements validation, and risk management responsibilities.
The posting requires a Bachelor's degree in a relevant field but explicitly states 'additional years of experience may be used in lieu of a degree,' so the degree requirement is set to None.
Docker and Kubernetes are listed together with 'and/or other Virtualization Software' — they are treated as interchangeable alternatives for the same virtualization requirement rather than two separate hard gates.
The full-scope polygraph requirement is captured under the TS/SCI clearance gate, consistent with the TopSecretSci classification.
Agile and Tableau appear under the 'Desired' (preferred) section.
Link analysis is called out as a required capability but names no specific tool; it is subsumed under the 'data visualization' skill rather than emitted as a standalone named technology.
Cloud infrastructure is listed as required but no specific cloud provider (AWS, Azure, GCP) is named.
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.
