• Apply patching, firmware upgrades, and routine maintenance to Windows Servers and virtualization platforms (VMware/Hyper-V).
• Perform lifecycle management of infrastructure assets including upgrades, migrations, and decommissioning.
• Support infrastructure-as-code principles and scripting for automation (e.g., PowerShell).
• Support firewall and endpoint protection configuration in coordination with the security administrator.
• Conduct vulnerability patch verification and participate in remediation workflows.
• Administer backup and disaster recovery operations using Veeam for on-prem and cloud workloads.
• Perform light database administration: access management, monitoring, and backup validation for SQL-based systems.
• Mentor team members and serve as a technical escalation point for complex infrastructure issues.
• Maintain up-to-date infrastructure documentation, including diagrams, standards, and procedures.
• Contribute to IT policies, procedures, and change management practices.
• Participate in the on-call rotation for after-hours support and incident response.
• Travel to branch or remote sites as required to support infrastructure deployment or troubleshooting.
