These skills ensure the design, maintenance, and optimization of reliable, high-performance core networks vital for organizational connectivity and service delivery.

What is the difference between Full Time Ip Core Network Engineer vs Network Operations Center (NOC) Engineer?

AspectFull Time Ip Core Network EngineerNetwork Operations Center (NOC) Engineer
CredentialsNetworking certifications (e.g., CCNA, CCNP), IP routing, switchingNetworking certifications, monitoring tools, troubleshooting skills
Work EnvironmentDesign, implement, and maintain IP core networksMonitor, troubleshoot, and support network infrastructure
Employer & IndustryTelecom providers, ISPs, large enterprisesTelecom, ISPs, data centers, managed service providers

Both roles require networking knowledge and certifications, but the Full Time Ip Core Network Engineer focuses on designing and maintaining core network infrastructure, while the NOC Engineer primarily monitors and troubleshoots existing networks. The former is more involved in network development, whereas the latter emphasizes operational support.

What are some common challenges a Full Time IP Core Network Engineer faces when managing large-scale network infrastructures?

A Full Time IP Core Network Engineer often encounters challenges such as ensuring high network availability, optimizing performance during peak traffic, and swiftly resolving complex routing or security issues. Managing upgrades and integrating new technologies into legacy systems can also be demanding, requiring careful planning and minimal service disruption. Additionally, effective collaboration with cross-functional teams is crucial for troubleshooting and implementing network changes while maintaining compliance and security standards.

What does a Full Time IP Core Network Engineer do?

A Full Time IP Core Network Engineer is responsible for designing, implementing, managing, and optimizing the core network infrastructure of an organization, focusing on IP-based networks. Their main duties include configuring and maintaining routers, switches, and firewalls, ensuring network security and reliability, troubleshooting issues, and supporting large-scale data traffic. They often work with technologies like MPLS, BGP, OSPF, and other networking protocols to ensure high availability and performance of the core network. This role is vital in telecom companies, ISPs, and enterprises with complex networking needs.

Position Summary


We are seeking a highly experienced Senior Core Network Engineer to lead the design, implementation, and optimization of our carrier-grade IP/MPLS and FTTH network infrastructure. This role is critical to ensuring scalability, resiliency, and performance across our core, aggregation, and access networks.


The ideal candidate has deep experience operating within an Internet Service Provider (ISP) or telecommunications environment, with hands-on expertise in Adtran access platforms, Arista routing/switching, and large-scale FTTH deployments.


This is a senior-level technical role requiring both architectural leadership and advanced operational troubleshooting capability.

Key Responsibilities
Core Network Architecture & Engineering

  • Design, implement, and maintain high-availability IP/MPLS core networks.
  • Engineer scalable BGP-based edge and peering infrastructure.
  • Architect resilient L2/L3 topologies for aggregation and backbone layers.
  • 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
    • 7–10+ years of experience in a carrier, ISP, or telecommunications environment.
    • 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.
