  • Maintain accurate network diagrams, IP schema, and routing policies.
  • Develop operational runbooks and engineering standards.

  • Required Qualifications

    • Extensive experience with:
    - Adtran platforms (OLT, aggregation, access equipment)
    - Arista switches and routers
    - 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.
    • Experience designing high-availability and redundant architectures.

Preferred Qualifications
• Experience with GPON and XGS-PON design.
• Familiarity with BRAS/BNG architectures.
