## Description

Job Summary : Role Summary We are seeking a hands-on Senior Network Engineer with deep expertise in Routing & Switching , ACI and VxLAN/EVPN (must-have). The ideal candidate will lead design, deployment, and operations of modern data center and campus networks, and bring strong capability in either NetDevOps/Automation (Python, Ansible, CI/CD) or VMware NSX for overlay/SDN.
Job Responsibilities : Key Responsibilities * Architecture & Design: o Design and implement L2/L3 networks across DC and campus environments. o Lead ACI/VxLAN/EVPN fabric designs (Multi-pod/Multisite, route types, control-plane considerations). o Create high-availability designs (ECMP, MLAG/vPC, BGP/OSPF/IS-IS). * Deployment & Operations: o Configure and maintain leaf-spine architectures, border gateways, and interconnects. o Troubleshoot complex issues across underlay/overlay, control plane, and data plane. o Perform capacity planning, performance tuning, and proactive monitoring. * Security & Segmentation: o Implement micro/macro segmentation (EVPN, NSX policies), firewall integration, and route filtering. o Ensure compliance with internal and industry standards. * Automation / NSX (one or both): o NetDevOps/Automation: Build network automation for config/validation (Python, Ansible, Nornir, Git). o VMware NSX: Design and manage NSX-T overlays, T0/T1, segments,
distributed firewall, and integrations. * Documentation & Governance: o Produce HLD/LLD, SOPs, runbooks, and maintain accurate network diagrams and CMDB entries. o Own change requests, risk assessments, and rollback plans. * Collaboration: o Partner with cloud, security, and platform teams on hybrid networking (AWS/Azure/GCP, SD-WAN). o Mentor junior engineers; contribute to standards and best practices.
