Why we read it this way (9)

The role is titled 'Systems Administrator' with no level modifier, so advertised seniority is Unspecified; however, the 5+ years of enterprise infrastructure experience and broad ownership scope support a Senior classification.

The 5+ years experience figure appears under 'Desirable Background' (the preferred/nice-to-have section), not under 'Required Skills'. It is nonetheless the only stated experience threshold and is treated as the effective minimum for total years.

A Bachelor's degree is listed under 'Desirable Background' and explicitly allows 'equivalent experience', so no hard degree requirement is set.

Compensation is described only as 'competitive, commensurate with experience' — no figures were provided.

Palo Alto and Fortinet are listed as interchangeable firewall examples ('or similar') under the required Networking bullet; Palo Alto is used as the primary with Fortinet as an alternative.

PowerShell, Python, and Bash are listed as interchangeable scripting options ('or') under the required Scripting & Automation bullet; PowerShell is used as the primary with Python and Bash as alternatives.

VMware ESXi cluster build experience is called out as 'a plus' within the VMware bullet, but the broader VMware vSphere management experience is in the Required Skills section and is marked required.

Ansible appears only under 'Desirable Background' and is listed as preferred.

The alt SOC (15-1252 Software Developers) was considered because the role includes scripting/automation, but the primary day-to-day work is clearly operating and maintaining infrastructure (Windows/Linux/VMware/networking), making 15-1244 the right fit.
