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:

· 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.

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.

Preferred:

NetDevOps / Automation

· Python (requests, netmiko/paramiko, NAPALM, pyATS),

· Ansible (Jinja2, inventories, roles),

· Version control (Git), CI/CD (GitHub Actions/GitLab CI),

· Network source of truth (Nautilus/NetBox),

· Telemetry/observability (SNMP, gNMI, streaming telemetry, Prometheus, Grafana).

VMware NSX (SDN)

· 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.

Nice-to-Have:

· EVPN route types (RT-2/RT-5), IRB, symmetric/asymmetric routing,

· Multisite/Multipod EVPN, DCI, MPLS L3VPN,
