A senior-level systems engineering and architecture role supporting IT modernization efforts for federal government clients. Day-to-day work involves analyzing mission and technical requirements, producing architecture documentation, evaluating solution alternatives, assessing interoperability and integration impacts, and developing transition roadmaps. The role suits an experienced engineer with a decade or more in systems engineering or solution architecture who is comfortable working across multidisciplinary technical and government stakeholder teams.

Why we read it this way (6)
The role's primary day-to-day work — analyzing requirements, developing architecture products, conducting trade studies, and supporting enterprise modernization — maps most closely to Computer Systems Analysts (15-1211). However, the 'Architect' framing and emphasis on solution/infrastructure architecture also creates a plausible case for 15-1299 (Computer Occupations, All Other), listed as the alternate.
No security clearance is explicitly required, though the role supports DHS/TSA Federal Government programs; candidates should expect a background investigation may be needed.
The preferred qualifications section lists experience with open architecture, API/interface standards, enterprise data exchange, ServiceNow, architecture repositories, SELC design reviews, and architecture governance — all treated as preferred, not required.
Certifications (INCOSE, TOGAF, FEAF/DoDAF, CompTIA Security+, ITIL Foundation, cloud, Agile/Scrum) are explicitly listed as preferred, not required.
The 10-year minimum is stated at the role level across systems engineering, solution architecture, systems integration, application/infrastructure architecture, or related IT modernization roles — not tied to any single named technology.
Ignored 4 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): systems engineering, solution architecture, enterprise architecture, open architecture.
