Why we read it this way (8)
The posting covers two sub-levels — 'Senior' (Bachelor's or 8+ years) and 'Principal' (Bachelor's or 10+ years) — under a single requisition. The header states '4+ years of related experience,' which appears to be a baseline floor for the requisition family rather than the actual gate for either named level. The overall years minimum is set to 4 per the posted header; the true gates for the named levels are 8 and 10 years respectively.
A Bachelor's degree in an IT-related field is listed as the formal requirement for both sub-levels, but the JD explicitly accepts 8+ or 10+ years of relevant IT experience in lieu of a degree, so the degree requirement is set to None.
The location is listed as 'Onsite' with no specific city or metro named in the posting; CBSA fields are left blank.
VMware and Hyper-V are listed together as the required hypervisor platforms — both are called out explicitly in the responsibilities and requirements sections, so each is captured as a hard gate with the other listed as an alternative (the JD treats them as the joint platform stack, not strict substitutes, but they are the closest interchangeable options in context).
DoD 8140 / Security+ CE is listed as a certification requirement under the 'What You'll Need to Succeed' section and is treated as a hard gate.
The TS/SCI clearance with a favorable polygraph is an explicit hard gate; the clearance requirement is set to TopSecretSci.
Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): patch management.
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.
