How this req sits in the market our data

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 (6)
The role has two primary locations — Woburn, MA (Boston metro) and Arlington, VA (Washington, DC metro). The Boston CBSA is used here as the first-listed location; the Washington-Arlington-Alexandria, DC-VA-MD-WV CBSA (47900) is equally applicable.
An active Secret clearance is a hard gate ('Who You Are' section). An active Top Secret clearance is listed under 'Even Better' and is preferred, not required.
The degree requirement is a BS with 5+ years of experience, but the posting explicitly notes 'equivalent experience considered,' which would normally make it None. However, the BS is stated as the primary gate alongside the experience floor, so it is treated as the minimum formal requirement with the caveat that equivalent experience may substitute.
Big data application experience and data pipeline development are required in the 'Who You Are' section but name no specific technology beyond Docker and Kubernetes; those responsibilities are captured through the named tools rather than as generic concepts.
The 'Even Better' section lists ETL pipelines, SQL, database storage, CI/CD tools, user interfaces/APIs, and user authentication — all marked preferred. 'TopSecret' is listed as a skill name here to represent the preferred active TS clearance, as it is a concrete credential called out in the 'Even Better' block.
Requires a Secret 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.
