- Lead network automation efforts for provisioning, monitoring, and configuration management.
2. Datacenter & Core Network Leadership
- Lead all technical operations of the primary ISP datacenter, ensuring high availability, fault tolerance, and scalability of infrastructure.
- Plan and implement the physical and logical design of network infrastructure including rack layout, cabling, power, cooling, and redundancy.
- Oversee all physical and logical network infrastructure within the main datacenter including routers, switches, firewalls, load balancers, and fiber optic connectivity.
- Manage data center layout, power, cooling, and physical security in accordance with international standards (e.g., TIA-942, ISO 27001).
3. IP Core & Routing Architecture (BGP/MPLS)
- Architect and maintain advanced BGP peering policies with upstream providers, IXPs, and CDN nodes for optimal route selection and traffic engineering.
- Design and manage MPLS Layer 2/3 VPNs, traffic segmentation, and QoS enforcement across the backbone.
- Maintain robust route-reflector topologies and redundancy plans in accordance with industry best practices.
- Oversee network convergence, route dampening, flap detection, and prefix filtering.
4. Subscriber Management (BNG)
- Oversee and optimize BNG systems (Broadband Network Gateways) for PPPoE, DHCP, NAT, dynamic IP assignment, and AAA (RADIUS/TACACS) integration.
- Implement traffic shaping, policy-based routing, and per-user QoS profiles.
- Ensure seamless integration with OSS/BSS platforms and subscriber provisioning systems.
- Configure and manage BNG systems for IP address management, session control, authentication (RADIUS/AAA), QoS, and traffic shaping.
- Oversee dynamic IP assignment, PPPoE, DHCP, and NAT configurations on BNG routers.
5. Access Network Management (GPON, ONT, OLT)
- Design, Supervise, optimize and maintain GPON network deployments and access networks, including provisioning, monitoring, and troubleshooting of OLT/ONT systems from vendors.
- Manage integration with BNG and aggregation layers to ensure efficient service delivery to subscribers.
- Define service profiles, VLAN tagging (TR-069, TR-101), and optical parameters (TX/RX, LOS, etc.) monitoring.
- Monitor performance and reliability of customer access networks and troubleshoot GPON-related issues.
- Ensure interoperability between GPON systems and BNG (Broadband Network Gateway) platforms for subscriber management.
6. SD-WAN & Edge Connectivity
- Lead design and deployment of SD-WAN technologies for enterprise customer connectivity and service delivery.
- Integrate SD-WAN with MPLS/IPSec backbones, including high availability, path selection, and real-time failover strategies.
- Support Zero Touch Provisioning (ZTP) and centralized orchestration using SD-WAN controllers.
7. Monitoring, Automation & Performance Management
- Implement robust NMS tools (Zabbix, Cacti, Nagios, LibreNMS, Prometheus, Grafana) for end-to-end visibility of all infrastructure.
- Automate configuration management using Ansible, Python, Netconf/YANG, and scripting tools.
- Monitor network KPIs (latency, jitter, packet loss) and enforce SLA compliance.
- Generate periodic reports on network health, usage statistics, incident reports, and capacity planning.
- Ensure 24x7 availability of critical services through structured NOC operations.
8. Security, Compliance & Risk Management
- Ensure infrastructure compliance with local and international standards (ISO 27001, GDPR, LI).
- Enforce perimeter and internal security using ACLs, firewalls, IDS/IPS, and DDoS mitigation.
- Conduct regular risk assessments and implement network segmentation and access control.
- Ensure all systems are hardened and patched regularly to prevent unauthorized access and service disruption.
- Implement DDoS mitigation strategies and monitor for anomalies in traffic behaviour.
- Comply with local and international regulations on data protection and lawful interception (LI).
9. Leadership & Stakeholder Management
- Lead a team of network and system engineers, NOC personnel, and support staff.
- Collaborate with cross-functional teams including product, customer service, and enterprise sales to deliver solutions.
- Manage vendor relationships, hardware lifecycle, licensing, and service-level agreements (SLAs).
- Participate in regulatory audits and ensure lawful interception (LI) infrastructure readiness.
- Lead, mentor, and grow a team of network engineers and support staff.
- Collaborate with vendors for procurement, support, and escalation of network hardware and software issues.
- Conduct technical training sessions for junior engineers on network technologies and best practices.
