Sr. Network SME

Sr. Network SME Technical requirements: Network Architecture & Design: Architect and deploy scalable, highly available LAN/WAN, SD-WAN, and Data Center networks (Nexus, Catalyst, ACI). Advanced Routing & Switching: Manage complex, multi-protocol routing environments utilizing BGP, OSPF, and EIGRP, alongside MPLS and Multicast architectures. Expert-level understanding of TCP/IP, OSI Model, Spanning Tree, QoS, and high-availability protocols (HSRP/VRRP). Proficiency with Cisco platforms including Catalyst 9000 switches, Nexus 9k/7k/5k switches, and ASR routers. Network Security: Architect, design, and implement high-availability network solutions integrating Palo Alto hardware and virtual appliances. Oversee deployment and tuning of NGFW, App-ID, User-ID, Threat Prevention, WildFire, and SSL/TLS Decryption. Manage multi-site deployments centrally using Palo Alto Panorama. Zscaler Expertise: Lead the architecture, configuration, and optimization of ZIA, ZPA, Zscaler Client Connector (ZCC), and Branch Connector environments. Tier-3 Support & Troubleshooting: Lead the resolution of critical incidents, isolating complex Layer 2/3 faults and performing packet analysis (Wireshark) to maintain maximum uptime. Collaboration & Leadership: Act as a technical mentor to junior engineers and a subject matter expert during cross-functional IT, cloud migration, or data center consolidation projects. Certifications: CCNP Enterprise, or CCIE (Cisco Certified Internetwork Expert), Palo Alto Networks Certified Network Security Engineer (PCNSE), Zscaler Certified Cloud Security Engineer (ZCCSE) highly preferred. Routine work: Patching network devices as per patch cadence. Visit various facilities within and outside India as and when required. Work with the core team on inventory and annual maintenance contract validation. Work closely with vendor and core team on the smooth running of monitoring tools Actively work on different projects assigned by client managers. Coordination with site leads for tracking progress on projects Work closely with teammates and stakeholders involved in the assigned projects Work closely with the service desk, end-user support and provide backend support Update in project tasks progress in tracking tools periodically Maintain all the documentation (Planning, operational standard work) related to the projects Facilitate knowledge/training to internal support team members Perform the Role of Product Owner and specialized operational support Involve in the new acquisition and migration projects On-call support to global service desk on critical escalation Sr. Network SME Technical requirements: Network Architecture & Design: Architect and deploy scalable, highly available LAN/WAN, SD-WAN, and Data Center networks (Nexus, Catalyst, ACI).
