Why we read it this way (7)
The clearance gate is nuanced: candidates must hold an active Secret clearance with the ability to obtain TS/SCI, OR already hold an active TS/SCI. The minimum hard gate is therefore an active Secret clearance; TS/SCI eligibility is required but may be obtained after hire.
The DoD 8570/8140 IAT Level II certification is a hard gate. Security+ CE is the most common qualifying cert; the full list of accepted alternatives (CCNA Security, CySA+, GICSP, GSEC, CND, SSCP) is captured in the alternatives field.
Virtualization experience (VMware, Hyper-V, or similar) is listed under qualifications but framed as 'familiarity with' — treated as preferred. NUTANIX is mentioned in the responsibilities narrative as an example platform.
Automation tools (PowerShell, Ansible, Terraform) and monitoring (Splunk) are framed as 'exposure to' and 'familiarity with' respectively — treated as preferred.
Security frameworks (NIST, FISMA, DISA STIG) are described as 'basic knowledge of' — treated as preferred.
The title 'Systems Administrator I' explicitly signals an entry/junior-level role, consistent with the 1–3 year experience requirement.
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.
