Responsibilities:
• Provide L3 support for network transport, routing, DNS, load balancing, NAC, and network automation incidents.
• Monitor network infrastructure components, including routers, switches, DNS/DHCP/IPAM, load balancers (Citrix NetScaler), routing policies, and segmentation boundaries.
• Execute routine network maintenance, such as firmware updates, configuration adjustments, device health checks, and routing optimization.
• Support onboarding and configuration of network devices following network engineering standards and architecture patterns.
• Troubleshoot connectivity, routing, segmentation, DNS resolution, and application delivery issues.
• Manage and optimize NetScaler ADC platforms.
• Oversee and improve Infoblox DDI, including zone design, DHCP scopes, IPAM hygiene, and large-scale scripted changes.
• Support network capacity planning, SRE practices, and performance optimization initiatives.
• Participate in network lifecycle activities, including device refresh, firmware upgrades, cloud connectivity expansion, and SD WAN/SDN adoption.
• Maintain network asset inventories, topology documentation, routing diagrams, and runbooks.
• Participate in DR rehearsals for network failover, including synthetic monitoring validation.
• Improve operational processes by identifying bottlenecks, recurring issues, and proposing automation opportunities.
• Collaborate with application teams, cloud teams, and vendors to resolve cross-domain network and load-balancing issues.
• Ensure network compliance, including change management, audit requirements, and stable configuration baselines.
• Maintain expert-level knowledge of routing protocols, network segmentation models, ADC traffic flows, and DNS architecture.
• Participate in knowledge sharing, operational reviews, and capability building within the team.
• Escalate high-impact network outages or routing issues according to the escalation matrix.
• Lead L2 Network Data analysts and organize an on-call rotation for the team
