Why we read it this way (6)
The posting titles this role 'Expert Software Developer' — 'Expert' is not a standard career-ladder band, but it functions as a seniority claim above Senior; mapped to Principal for the level advertised in the title. The actual requirements (10+ years, full-stack IC work) are consistent with a Senior-level role.
A fully active polygraph clearance is explicitly required ('Must be fully cleared with a recent polygraph'). This is treated as a TS/SCI-with-polygraph gate.
Java and Python are listed as interchangeable options for backend development ('Java and/or Python'); Angular and JavaScript are both independently required for front-end work and are emitted as separate skills.
CI/CD pipeline support is mentioned in the required responsibilities section but specific tooling (Jenkins, GitLab) appears only under Desired Qualifications; CI/CD is captured as preferred accordingly.
The degree requirement accepts 'an equivalent combination of education and experience,' so no minimum degree is hard-gated.
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.
