• Participate in a shared on-call rotation providing after-hours and weekend support for critical outages; assist with Tier 1/2 tickets during peak volume, backlogs, or staff absences.
• Travel to company sites and project locations for on-site support, installations, and technology deployments.
• Provide architectural input and recommendations on the Microsoft 365 and Azure platform roadmap, partnering with IT leadership on endpoint management strategy, tenant configuration standards, and technology lifecycle planning.
• Own software and cloud licensing budget planning for supported platforms, including cost forecasting, vendor contract review, and renewal negotiation.
