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 (7)
The role sits at the boundary between systems integration/operations (15-1244) and software development (15-1252): 70% of the work is integrating FOSS/COTS/internally developed applications, which leans toward integration and systems administration, but the posting also calls for prototyping cloud systems and RESTful/microservice development.
The Bachelor's degree requirement is waived by 'or equivalent experience', so the degree requirement is set to None.
Secret clearance is a hard gate: candidates must hold or be able to obtain a DoD Secret clearance and must be US citizens.
Seniority is assessed as Mid (3+ years required, no explicit senior/lead scope); the title carries no level indicator.
The 'Highly Desirable Skills' section explicitly asks for hands-on experience in two or more of those areas, but the section heading frames them as desirable rather than required, so all are marked preferred.
Messaging Middleware and object-oriented/functional programming were omitted from skills as they name no specific technology or tool.
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.
