Why we read it this way (6)
The role is titled 'Systems Engineer' with no seniority modifier, but the 5–6+ years requirement and end-to-end infrastructure ownership scope support a Senior classification.
SOC classification is a close call: the role primarily operates and administers Microsoft/Azure infrastructure (15-1244) rather than building software, but cloud architecture design duties add some 15-1252 flavor — 15-1244 wins on balance given the Tier 2/3 support, patching, and AD/DNS administration emphasis.
Teams, SharePoint, and OneDrive appear in the responsibilities narrative as part of the M365 administration scope rather than in a discrete required-qualifications block; they are listed as preferred accordingly.
PowerShell scripting is listed under Preferred Qualifications as 'familiarity with scripting (PowerShell or similar)' — treated as preferred with common scripting alternatives noted.
Certifications (Azure, Microsoft 365) are explicitly called 'a plus but not required' — listed as preferred.
The posting mentions 10% travel throughout the Midwest; the primary onsite locations are Barrington and Chicago, IL — mapped to the Chicago-Naperville-Elgin CBSA.
