Why we read it this way (10)
The job title reads 'Full Stack Developer / Architect' but the body consistently frames the role as a Senior .NET Systems Architect / Developer — advertised seniority is taken from the body framing ('Senior').
The degree requirement accepts 'equivalent experience' in lieu of a Bachelor's degree, so no minimum degree is hard-gated.
The clearance gate states 'Active Top Secret clearance' as required and 'Able to obtain TS/SCI' as an additional expectation; the role is classified as TopSecret (not TopSecretSci) because TS/SCI is framed as a future goal, not a current hard gate.
COBOL/mainframe familiarity is listed under Required Qualifications as 'Familiarity with legacy systems, including COBOL or mainframe environments' — treated as a required capability even though 'familiarity' softens the depth.
Oracle and SQL Server appear together under Required Qualifications as 'Oracle and/or Microsoft SQL Server'; emitted as one skill (Oracle) with SQL Server as an alternative.
Databricks is listed under Preferred Qualifications as 'desired for future-state capabilities'; the Databricks Data Engineer Certification is similarly preferred.
AI/ML and advanced analytics tools are mentioned under Preferred Qualifications but name no specific technology, so they are omitted from the skills list.
Data modeling and database design appear under Preferred Qualifications; no specific tool is named, so they are omitted.
The alt SOC (15-1211 Computer Systems Analysts) reflects the significant architecture analysis and system-integration advisory work described alongside the hands-on development duties.
Requires a Top 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.
