• IT Operations & Infrastructure: Support core IT functions including Microsoft 365 administration, Sharepoint Management, endpoint troubleshooting, and robust backup management.
• Security & Monitoring: Maintain email security frameworks (ATP, anti-spam, DMARC/DKIM/SPF) and proactively monitor client systems to pre-empt technical issues.
• Client & Vendor Collaboration: Act as a trusted technical contact, providing face-to-face client support, end-user training, and managing vendor escalations.

About you
