1. 1. IP Core Infrastructure Management

• Monitor and supervise IP Core network elements (main routers, DCGW, spine, leaf, CBIS, inter-DC and backbone links).
• Perform configuration, commissioning, and validation of IP Core routers and switches in coordination with data center and operations teams.
• Manage software upgrades, firmware updates, and patches on IP Core devices.
• Conduct acceptance tests, connectivity validation, and end-to-end traffic flow verification.

1. 2. Technical Support & Incident Management

• Analyze and troubleshoot IP Core network incidents, alarms, and service degradations.
• Identify root causes impacting routing, forwarding, and redundancy mechanisms.
• Implement corrective and preventive actions to maintain service stability.
• Escalate complex issues to vendors or higher-level engineering teams when required.
• Provide 2nd/3rd level support and ensure timely incident resolution in line with SLAs.

1. 3. Network Performance Optimization

• Continuously monitor IP Core performance, latency, packet loss, and bandwidth utilization.
• Analyze KPIs and traffic patterns across DCGW, spine–leaf fabric, and inter-DC links.
• Propose and implement optimization actions to improve throughput, resiliency, and load balancing.
• Support capacity planning and scaling of IP Core and data center infrastructure.

1. 4. Documentation & Reporting

• Prepare technical reports related to incidents, changes, and optimization activities.
• Maintain accurate and up-to-date IP Core network documentation, configurations, and topology diagrams.
• Update inventory databases for routers, switches, links, and interfaces.
• Produce periodic performance, availability, and SLA reports.

1. 5. Collaboration with Operations & Projects

• Coordinate with NOC, transmission, data center, and service teams for end-to-end service assurance.
• Participate in IP Core and data center network expansion, migration, and modernization projects.
• Provide technical input during design, implementation, migration, and acceptance phases.

1. 6. Vendor & Contractor Coordination

• Interface with IP Core equipment vendors and service providers.
• Follow up vendor tickets and ensure compliance with technical and operational requirements.
• Validate delivered equipment, configurations, and services according to defined standards.

1. 1.1.5 Required Skills
1. Technical Skills

• Strong knowledge of IP networking and routing technologies (BGP, OSPF, IS-IS, ECMP).
• Solid understanding of IP Core and data center architectures (DCGW, spine–leaf, inter-DC connectivity).
• Experience with high-capacity IP Core routers and data center switches.
• Knowledge of traffic engineering, QoS, and redundancy mechanisms.

1. Tools & Systems
