Job Description:

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:
    • 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).
    • 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, segments, distributed firewall, and integrations.
    • Produce HLD/LLD, SOPs, runbooks, and maintain accurate network diagrams and CMDB entries.
    • Own change requests, risk assessments, and rollback plans.
    • 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.
  • 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.

Preferred

  • NetDevOps / Automation
    • 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
  • Cloud networking (AWS TGW, Azure vWAN, GCP VPC)

Qualifications

  • Bachelor’s in CS/EE/IT or equivalent experience.
  • Certifications (preferred): CCNP/CCIE, JNCIP/JNCIE, Arista ACE, VMware VCP-NV.
  • Experience: 8+ years in network engineering; 4+ years hands-on VxLAN/EVPN.
