Core Responsibilities

Primary Functions

Proactively monitor the health and performance of the network infrastructure, including routers, switches, firewalls, servers, and carrier circuits, using a suite of advanced monitoring tools (e.g., SolarWinds, Nagios, Zabbix).
Serve as the initial point of contact for all network-related alarms, alerts, and performance degradation events, creating and managing trouble tickets with meticulous detail.
Perform initial triage and troubleshooting of network issues across LAN, WAN, wireless, and VoIP environments to identify root causes and attempt first-call resolution.
Execute predefined standard operating procedures (SOPs) for fault isolation, problem resolution, and system diagnostics to ensure consistent and efficient responses.
Methodically document all incidents, including symptoms, diagnostic steps, resolution activities, and timestamps, within the ticketing system (e.g., ServiceNow, Jira).
Escalate complex or unresolved issues to Tier 2/3 engineers, other internal IT teams, or external service providers/vendors in a timely and effective manner.
Manage the lifecycle of trouble tickets, ensuring they are updated regularly and driven to resolution in accordance with Service Level Agreements (SLAs).
Conduct basic device configuration and command-line interface (CLI) diagnostics on network hardware from vendors like Cisco, Juniper, and Arista.
Coordinate with field technicians and remote personnel to assist with physical hardware troubleshooting, replacements, and circuit turn-ups.
Communicate network status, outages, and maintenance activities clearly and professionally to internal stakeholders, management, and affected end-users.
Participate in and support scheduled network maintenance activities, which may occur during off-peak hours, to minimize impact on business operations.
Monitor and manage network backup jobs and perform basic restoration procedures as required.
Perform health checks on network systems and applications following maintenance or incident resolution to verify the restoration of full functionality.
Assist in the creation and maintenance of technical documentation, including network diagrams, knowledge base articles, and operational procedures.
Analyze system logs and event data to identify trends, potential problems, and opportunities for proactive intervention.
Manage and respond to inquiries and support requests that arrive via phone, email, and automated alerting systems.
Correlate multiple network events to identify larger, systemic issues and prevent cascading failures.
Provide support for VPN connectivity issues, assisting remote users with access problems and troubleshooting client configurations.
Verify and confirm service restoration with end-users or automated systems upon resolution of an incident.
Participate in shift turnover meetings to ensure a seamless transfer of knowledge regarding ongoing incidents, planned maintenance, and network status to the incoming team.

Secondary Functions

Assist in generating performance reports and fulfilling ad-hoc data requests related to network incidents, uptime, and SLA metrics.
Contribute to the continuous improvement of monitoring tools, alerting thresholds, and operational procedures to enhance proactive detection capabilities.
Collaborate with engineering teams and service providers to provide diagnostic data and support during the resolution of escalated, complex issues.
Participate in team meetings, ongoing training sessions, and professional development to maintain a high level of technical skill and operational readiness.
