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 Net Dev Ops /Automation (Python, Ansible, CI/CD) or VMware NSX for overlay/SDN.

• Architecture & Design:
• Design and implement L2/L3 networks across DC and campus environments.
• Lead ACI/VxLAN/EVPN fabric designs (Multi-pod/Multisite, route types, control-plane considerations).
• Create high-availability designs (ECMP, MLAG/vPC, BGP/OSPF/IS-IS).
• Deployment & Operations:
• Configure and maintain leaf-spine architectures, border gateways, and interconnects.
• Troubleshoot complex issues across underlay/overlay, control plane, and data plane.
• Perform capacity planning, performance tuning, and proactive monitoring.
• Security & Segmentation:
• Implement micro/macro segmentation (EVPN, NSX policies), firewall integration, and route filtering.
• Ensure compliance with internal and industry standards.

• Data Center Fabrics:
  VxLAN/EVPN (mandatory) with practical experience in DC leaf-spine design.
• Vendor Proficiency:
  One or more—Cisco (Nexus/IOS-XE), Arista EOS, Juniper QFX/EX.
• Troubleshooting:
  Packet analysis, control-plane convergence, FIB/ARP/ND, MTU/MSS, ECMP.

• Python (requests, netmiko/paramiko, NAPALM, pyATS),
• Ansible (Jinja2, inventories, roles),
• Version control (Git), CI/CD (Git Hub Actions/Git Lab CI),
• Network source of truth (Nautilus/Net Box),

• NSX-T design and operations: T0/T1 gateways, segments, overlay transport zones,
• Distributed firewall, security groups, micro-segmentation,
• Integration with physical gateways, north-south routing,
• Edge clusters, load balancer, policy automation.

• EVPN route types (RT-2/RT-5), IRB, symmetric/asymmetric routing,
• Multisite/Multipod EVPN, DCI, MPLS L3
  
  VPN,
• SD-WAN (Viptela, Prisma, Fortinet),
• Cloud networking (AWS TGW, Azure vWAN, GCP VPC),
