The role requires strong technical knowledge of transmission technologies, fiber-optic infrastructure, splicing and ISP operations, along with effective team and vendor management skills.

Key Responsibilities

• Manage and oversee daily operations, maintenance, and performance of the ISP transmission and fiber network infrastructure, ensuring high availability, stability, redundancy, and SLA compliance.

• Monitor transmission links, equipment, interfaces, alarms, optical levels, and network utilization while coordinating with NOC and relevant technical teams to ensure smooth service delivery.

• Lead fault and incident management activities, including identification, troubleshooting, escalation, and restoration of fiber and transmission-related issues such as fiber cuts, high-loss links, equipment failures, power issues, and customer-impacting outages.

• Conduct Root Cause Analysis (RCA) for major and recurring incidents, establish corrective and preventive actions, and ensure continuous improvement in network reliability and restoration performance.

• Support planning, execution, and monitoring of FTTH/FTTx network expansion projects, including fiber deployment, route planning, splicing, termination, testing, and technical acceptance activities.

• Supervise fiber installation, splicing, and testing activities using OTDR, optical power meter, VFL, and other fiber-testing tools while ensuring proper optical performance, labeling, documentation, and quality standards.

• Develop and implement preventive maintenance plans for fiber infrastructure, transmission equipment, and OSP assets to minimize service disruption and identify potential risks proactively.

• Lead and manage fiber operations teams, including engineers, supervisors, technicians, and field personnel by allocating tasks, monitoring performance, providing technical guidance, and ensuring operational readiness.

• Manage third-party service providers, contractors, and vendors by monitoring service quality, productivity, compliance, technical support, and ensuring completed work meets approved design, quality, and safety standards.

• Maintain accurate documentation of fiber routes, splice diagrams, core allocation, network topology, GIS records, asset information, fault history, maintenance activities, and operational reports.

• Ensure proper inventory management of fiber cables, closures, TJBs, FDBs, splitters, ODF, patch panels, tools, and critical spare materials required for smooth operations.

• Ensure compliance with company standards, safety procedures, change management processes, and quality requirements during network deployment, maintenance, and restoration activities.

• Coordinate with Customer Support, NOC, Core Network, and other departments to resolve customer-impacting issues, prioritize critical outages, and support enterprise and high-priority customer restoration.

• Monitor operational KPIs including network availability, fault resolution time, MTTR, recurring incidents, preventive maintenance compliance, and service performance, providing improvement recommendations to management.

• Perform any other technical, operational, or management-related tasks assigned by the supervisor or management.
