Why we read it this way (6)
The role is genuinely ambiguous between data/pipeline architecture (15-1243) and general software development (15-1252). The emphasis on designing and implementing batch and streaming data pipelines, ETL on large unstructured datasets, and named tools (Kafka, Spark, Prefect) tips it toward 15-1243, but the CI/CD and containerization duties are typical of 15-1252.
The TS/SCI with polygraph clearance is an active hard gate — the posting explicitly states candidates will not be nominated for new clearances, meaning applicants must already hold one.
The degree requirement is a STEM bachelor's degree (computer science, statistics, data analytics, computer engineering, mathematics, or equivalent). Because no equivalent-experience substitution is offered, this is treated as a hard requirement.
The '5-7 years' range is treated as a minimum of 5 years at the role level.
US Intelligence Community experience is listed under Preferred Qualifications and is not captured as a required skill since it is domain knowledge rather than a named technology.
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.
