What this job asks for AI summary

“or” means any one of them counts — you don't need all of them.
We read this from the posting text with AI. Skim the description below before ruling yourself out.
Why we read it this way (8)
No work location or metro area is specified in the posting. Given the federal client context (TSA/DHS mentioned as preferred experience), the role is likely in the Washington, DC area, but this cannot be confirmed from the JD alone.
The role is classified as Computer Systems Analysts (15-1211) rather than a software developer SOC because the primary day-to-day work is enterprise architecture analysis, governance, and advisory — not building or shipping software. 15-1299 (Computer Occupations, All Other) is noted as a plausible alternative given the breadth of the architect scope.
US citizenship is explicitly required by the federal client, though no specific security clearance level is stated as a hard gate.
TOGAF, FEAF, and DoDAF appear together as interchangeable framework options under Preferred Qualifications; they are captured as a single preferred skill with alternatives. The same frameworks appear again under Preferred Certifications — the certification versions are subsumed in the same entry.
Ins-Pi / YouDesign is listed in the preferred tools section but is a niche/proprietary tool with very limited public documentation; it is omitted from the skills list as it cannot be reliably named as a canonical technology.
The 15-year minimum is stated as experience across a broad set of disciplines (Enterprise Architecture, Solution Architecture, Systems Engineering, IT Modernization, Systems Integration, Technical Leadership) — not tied to any single named technology, so it is captured as total experience rather than per-skill years.
No compensation range is provided in the posting.
Ignored 3 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): Enterprise Architecture, Solution Architecture, Systems Engineering.
