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.

Key Responsibilities

• 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.
• Automation / NSX (one or both):
• NetDevOps/Automation: Build network automation for config/validation (Python, Ansible, Nornir, Git).
• VMware NSX: Design and manage NSX-T overlays, T0/T1 gateways, segments, distributed firewall, and integrations.
• Documentation & Governance:

• Partner with cloud, security, and platform teams on hybrid networking (AWS/Azure/GCP, SD-WAN).
• Mentor junior engineers; contribute to standards and best practices.

Must-Have Skills

• Routing & Switching: BGP, OSPF/IS-IS, eBGP/iBGP, route redistribution, policy-based routing, QoS.
• Data Center Fabrics: VxLAN/EVPN (mandatory) with practical experience in DC leaf-spine design.
• Troubleshooting: Packet analysis, control‑plane convergence, FIB/ARP/ND, MTU/MSS, ECMP.
