What this job asks for AI summary
A cybersecurity firm supporting a classified federal program (CESO) in Arlington, VA seeks a senior technical leader to drive database modernization and cloud migration for a high-security web services platform. The role blends hands-on database architecture and DevSecOps engineering with people management — leading senior engineers, setting technical strategy, and owning delivery across Agile teams. Requires an active TS/SCI clearance and is fully onsite five days per week.

Why we read it this way (8)
The title 'Principal Engineer / Technical Lead' is advertised as Principal, but the actual scope — leading a single program's teams, 12+ years experience, no org-wide authority described — is consistent with a Senior-level role on a normal career ladder.
The role has substantial people-management duties (performance management, career development, succession planning), which would normally point to 11-3021 (Computer and Information Systems Managers). However, the posting also demands deep hands-on database architecture and DevSecOps engineering work, making 15-1243 (Database Architects) a genuine runner-up. 11-3021 was selected because management and technical leadership responsibilities are given equal or greater prominence than individual-contributor engineering.
The posting lists 'PSSQL' in the requirements text, which is interpreted as PostgreSQL (a common abbreviation variant). Oracle 19c is listed separately under the 'Experience with the following technologies' block and is treated as a required technology alongside the broader Oracle requirement.
'Webservices' appears in the required technologies list but names no specific product or framework, so it was omitted per the generic-concept rule.
Degree requirement is set to None because the posting explicitly states 'Additional years of experience may be considered in lieu of degree.'
The preferred qualifications (DISA experience, legacy-to-modern migration leadership, high-availability federal systems, government stakeholder coordination) are not captured as skills because they describe domain experience rather than named technologies or tools.
Generative AI appears only in a leadership/governance context ('guide the responsible adoption of generative AI tools') rather than as a technical skill gate, so it is marked preferred.
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.
