Core Responsibilities

Primary Functions

Proactively monitor the health, performance, and security of the global network infrastructure, including LAN, WAN, wireless, and data center networks, using enterprise-grade monitoring tools (e.g., SolarWinds, Nagios, Datadog).
Act as the first point of contact for all network-related incidents, creating and managing tickets in systems like ServiceNow or Jira from detection through to resolution.
Perform initial triage and in-depth troubleshooting of network outages and performance degradations, including issues with routers, switches, firewalls, load balancers, and wireless access points.
Analyze network traffic patterns using tools like Wireshark and NetFlow to identify anomalies, diagnose complex connectivity problems, and pinpoint sources of latency.
Execute established incident management protocols, ensuring timely escalation of unresolved issues to Tier 2/3 Network Engineers, other IT teams, or external vendors.
Provide clear, concise, and timely communication regarding incident status, impact, and resolution progress to stakeholders, management, and affected user groups.
Implement pre-approved, standard network changes and configurations during scheduled maintenance windows, following strict change management procedures.
Perform daily, weekly, and monthly system checks to ensure the optimal operation of all network components and services.
Respond to and resolve alerts from various monitoring systems, correlating events to identify root causes rather than just treating symptoms.
Manage and maintain the health of network hardware from vendors such as Cisco, Juniper, Arista, and Palo Alto Networks.
Troubleshoot and resolve issues related to core networking protocols, including TCP/IP, BGP, OSPF, EIGRP, and Spanning Tree.
Assist in the documentation of network diagrams, procedures, and runbooks to build a comprehensive knowledge base for the NOC team.
Participate in a rotating shift schedule to provide 24/7/365 coverage for the Network Operations Center.
Conduct root cause analysis (RCA) for major incidents, documenting findings and proposing preventative measures to avoid future occurrences.
Collaborate with telecommunication providers and third-party vendors to troubleshoot and resolve circuit-related issues and service disruptions.
Verify and test network redundancy and failover mechanisms to ensure business continuity and disaster recovery readiness.
Support the deployment of new network hardware and infrastructure under the guidance of senior engineers.
Monitor and manage DNS, DHCP, and IPAM (DDI) services to ensure their availability and proper functioning.
Generate and review regular reports on network performance, availability, and incident trends to identify areas for improvement.
Uphold and enforce network security policies by monitoring for unauthorized access, security threats, and policy violations in coordination with the security team.
Isolate and resolve network-based VoIP and video conferencing quality issues, such as jitter, packet loss, and latency.

Secondary Functions

Support senior engineers in testing and validating new network technologies, software versions, and configurations in a lab environment.
Contribute to the continuous improvement of NOC processes, monitoring tools, and operational procedures.
Assist in training and mentoring junior analysts, sharing knowledge and best practices for network monitoring and troubleshooting.
Manage relationships with hardware and circuit vendors, tracking service level agreements (SLAs) and support tickets.
