Why we read it this way (8)
The posting titles this role 'System Administrator Level 2', which maps to a mid-level designation in the company's internal ladder, but the 10-year experience requirement and TS/SCI with Polygraph gate reflect Senior-level scope on the broader market ladder.
A Bachelor's degree in a technical discipline is listed as required, but the JD explicitly allows substitution with 5 additional years of experience — the degree requirement is therefore set to None.
The clearance requirement is TS/SCI with 'appropriate Polygraph', which is a hard gate for this role.
DoD 8570 IAT Level II certification (e.g., CompTIA Security+ CE) is explicitly required; CompTIA Security+ is listed as the canonical example but other qualifying IAT Level II certs are accepted.
VMware, KVM, and Hyper-V are listed as interchangeable virtualization options; Docker is listed alongside them but is a distinct containerization technology and is emitted separately.
Bash and PowerShell are listed as 'and/or', treated as interchangeable scripting options under one skill entry.
No work location or CBSA is specified in the posting; the TS/SCI with Polygraph requirement strongly implies an on-site position in a cleared facility, but no city or state is named.
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.
