Why we read it this way (5)
The degree requirement is effectively waived: the posting accepts 5 additional years of systems administration experience in lieu of a Bachelor's degree, so the degree requirement is set to None.
Windows is listed under Minimum Qualifications as 'Familiarity with Windows' — softer language than RHEL, but still within the required section; it is treated as a hard gate accordingly.
AWS appears under Preferred Qualifications and is marked as preferred.
An active TS/SCI with Polygraph is a hard gate for this role.
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.
