• Provide expert support for application servers.
• Perform advanced troubleshooting for I/O, CPU, memory, driver, and compatibility issues.
• Automate recurring activities with PowerShell.
• Master storage protocols SMB3, NFSv3/v4, iSCSI, and Fibre Channel.
• Understand and administer network environments based on TCP/IP, VLAN, LACP, routing, ACL, and firewalling.
• Participate in Datacenter connectivity management.
• Understand ToR, Spine-Leaf architectures, and redundancy mechanisms.
• Diagnose network issues related to storage: latency, drops, congestion, and performance.
• Participate in architecture studies around storage, Windows Server, and virtualization.
• Contribute to the definition of infrastructure standards.
• Technically lead major projects such as migrations, platform evolutions, or hardware refreshes.
• Perform capacity analyses and anticipate future needs.
• Write and maintain technical documentation.
• Produce DATD, DATG, technical procedures, and operational documents.
• Provide N3 support during complex incidents impacting production.
• Perform root cause analyses.
• Identify recurring trends and propose preventive actions.
