• Provide L2/L3 production support, managing complex incidents, service requests, and Requests for Change (RFCs) across network environments.

• Lead network diagnostic troubleshooting during high-priority incidents and drive rapid root-cause analysis (RCA) and preventive resolution.

• Perform proactive performance monitoring, capacity planning, latency optimization, and bandwidth utilization tracking.

• Participate in rotating on-call shifts and scheduled after-hours maintenance activities.

2. Network Security, Governance & Compliance

• Implement and manage next-generation firewalls (e.g., Palo Alto, Fortinet, Cisco ASA/Firepower), VPN gateways, and intrusion prevention systems (IPS).

• Define and enforce network access control (NAC), perimeter security policies, micro-segmentation, and zero-trust security frameworks.

• Oversee routine firmware updates, vulnerability patching, security risk assessments, and network audit compliance.

• Drive Business Continuity Planning (BCP) and Disaster Recovery (DR) execution, ensuring seamless network failover protocols.

3. Automation, Cloud & Infrastructure Projects

• Collaborate with enterprise architects and cloud operations teams to build and manage hybrid-cloud connectivity (AWS DirectConnect, Azure ExpressRoute, GCP Cloud Interconnect).

• Develop and maintain network automation scripts (Python, Ansible, Terraform) to streamline configuration deployments and routine operational tasks.

• Manage vendors, service providers, and telco carriers for WAN/SD-WAN link provisioning, circuit maintenance, and SLA compliance.

• Create, update, and maintain comprehensive network topology diagrams (Visio), Standard Operating Procedures (SOPs), runbooks, and inventory records.
