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.

Estimated from BLS employment for this occupation and area, per-skill prevalence across our listing corpus, and published wage benchmarks — as of Aug 11, 2026. It is a model, not a headcount.
Why we read it this way (5)
The posting states 'Must be fully cleared with a recent polygraph' — this is treated as a TS/SCI with polygraph hard gate, though the specific clearance level is not spelled out by name.
The 12+ years experience figure is tied to the RFQ's labor category and is paired with a Master's degree in the posting's framing; however, the posting also accepts a Bachelor's or equivalent experience, so the degree requirement is set to None.
Containerization/microservices and DevOps practices appear under Desired Qualifications but no specific container tool (e.g. Docker, Kubernetes) is named — only the concept is mentioned, so no skill entry was created for it.
The role title is 'Software Engineer' with no level modifier; seniority is assessed as Senior based on the 12+ years experience requirement and the expert-level framing, not from the title itself.
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.
