• Experience architecting or overseeing endpoint management (Intune/MDM) and SaaS collaboration platforms (Microsoft 365, Box, Zoom) at enterprise scale
• Demonstrated experience operating within a formal ITIL-based ITSM framework — Incident, Major Incident, Problem, Change, Knowledge, Service Request, and Configuration Management — ideally on ServiceNow
• Experience designing or reviewing contact center/telephony solutions (AWS Connect or equivalent) as a secondary/contributing skill
• Strong stakeholder management and the ability to communicate architecture trade-offs to both technical teams and account/customer governance
• Experience operating under a managed-services SOW with defined coverage windows, deadband/volumetric clauses, and multi-tower delivery teams

Preferred Qualifications
