Why we read it this way (6)
Location is not specified in the posting; CACI notes the salary range is a national average because the role 'can be worked in more than one location.' No CBSA could be determined.
The role blends systems engineering (requirements management, traceability, compliance matrices) with formal test/verification work, making it a genuine toss-up between Computer Systems Analysts (15-1211) and Software QA Analysts and Testers (15-1253). The requirements-management and cross-team coordination emphasis tips it toward 15-1211.
IAT Level II or III certification is a hard gate; Security+, CISSP, and CASP are listed as examples of qualifying certs — captured as a single required skill with alternatives.
XML and JSON appear only under the Desired section as experience with software-defined interfaces, so both are marked preferred. They are listed as interchangeable alternatives to each other per the posting's 'either XML or JSON' framing.
The title says 'Staff' but the requirements (5+ years, component/project-level scope) are consistent with a Senior-level role rather than a true Staff/cross-team technical authority band.
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.
