  • Lead IPv4/IPv6 dual-stack strategy and deployment.

FTTH & Access Network Engineering

  • Design and support FTTH (Fiber-to-the-Home) GPON/XGS-PON environments.
  • Configure and manage Adtran OLTs, aggregation platforms, and access systems.
  • Support subscriber provisioning models and service delivery frameworks.
  • Collaborate with outside plant (OSP) and field engineering teams.

Routing & Switching (Arista Focus)

  • Deploy and support Arista switching and routing platforms in core and aggregation roles.
  • Implement EVPN/VxLAN where applicable.
  • Optimize traffic engineering, QoS, and multicast routing.

ISP Operations & Optimization

  • Support upstream providers, IX peering, and transit relationships.
  • Perform traffic capacity planning and bandwidth forecasting.
  • Lead root cause analysis of network outages and performance incidents.
  • Develop monitoring, alerting, and performance visibility standards.
  • Participate in Tier 3 escalation and on-call rotation.

Automation & Documentation

  • Drive automation initiatives (Python, Ansible, etc.).
  • Maintain accurate network diagrams, IP schema, and routing policies.
  • Develop operational runbooks and engineering standards.


  • Required Qualifications

         - FTTH architecture and subscriber networks
    Deep expertise in:
        - BGP (iBGP, eBGP, route reflectors)
        - OSPF and/or IS-IS
        - MPLS (L2VPN/L3VPN preferred)
        - VLAN, QinQ, QoS
        - Multicast (PIM)
    Experience with ISP edge routing and peering design.
    Strong troubleshooting skills in production networks serving large subscriber bases.
