Core Responsibilities

Primary Functions

Design, implement, and support complex telecommunications networks, including Local Area Networks (LANs), Wide Area Networks (WANs), and wireless systems.
Configure, manage, and maintain essential network hardware such as routers, switches, firewalls, and load balancers from leading vendors like Cisco, Juniper, and Arista.
Oversee the entire lifecycle of Voice-over-IP (VoIP) and Session Initiation Protocol (SIP) telephony systems, including Private Branch Exchange (PBX) and call center infrastructure.
Conduct comprehensive radio frequency (RF) site surveys, spectrum analysis, and performance tuning for wireless networks, including enterprise Wi-Fi, cellular (4G/5G), and microwave links.
Develop and maintain meticulous network diagrams, system documentation, and Standard Operating Procedures (SOPs) for network configuration, troubleshooting, and maintenance.
Proactively monitor network performance, availability, and capacity using tools like SolarWinds, PRTG, or Nagios to identify and resolve issues before they impact services.
Lead advanced troubleshooting efforts for complex network outages and performance degradation, performing deep-dive Root Cause Analysis (RCA) and implementing lasting corrective actions.
Plan and flawlessly execute network upgrades, infrastructure migrations, and equipment replacements with minimal disruption to business operations, often during scheduled maintenance windows.
Collaborate effectively with cross-functional teams, including systems administrators, cybersecurity analysts, and software developers, to ensure the seamless integration of network services.
Manage relationships with telecommunications carriers and service providers, overseeing circuit provisioning, validating Service Level Agreements (SLAs), and handling issue escalations.
Implement and fortify network security measures, including Access Control Lists (ACLs), site-to-site VPNs, and Intrusion Prevention Systems (IPS), in alignment with the cybersecurity team.
Evaluate, test, and recommend new networking technologies, hardware, and software to enhance network performance, reliability, and overall cost-effectiveness.
Serve as a final escalation point and subject matter expert for the Network Operations Center (NOC) and IT help desk teams on high-priority incidents.
Manage the physical infrastructure of data centers and network closets, ensuring proper cabling standards, power distribution, and environmental controls are maintained.
Develop, test, and maintain robust disaster recovery and business continuity plans for all critical telecommunications infrastructure to ensure operational resilience.
Perform detailed analysis of network traffic patterns using packet capture tools to optimize routing, improve Quality of Service (QoS), and accurately plan for future capacity needs.
Lead or actively participate in major telecommunications projects by defining technical scope, creating project plans, and ensuring the timely delivery of key objectives.
Ensure all network infrastructure remains compliant with relevant industry standards and regulatory requirements, such as FCC regulations or PCI-DSS.
Design, install, and troubleshoot fiber optic cabling infrastructure, including activities like fusion splicing, mechanical termination, and testing with OTDR equipment.
Automate routine network administration tasks and deployments using scripting languages like Python, Ansible, or PowerShell to improve efficiency and reduce human error.
Manage and configure Unified Communications (UC) platforms, seamlessly integrating voice, video conferencing, and instant messaging services across the enterprise.
Conduct regular security audits and vulnerability assessments of the network infrastructure and implement comprehensive remediation plans to mitigate risks.

Secondary Functions

Train, mentor, and provide technical guidance to junior engineers and network technicians.
Manage vendor relationships, negotiate contracts, and evaluate the performance of third-party service providers and hardware suppliers.
Assist in the development of departmental IT budgets and provide accurate forecasting for network-related capital and operational expenses.
Create and present detailed technical reports, performance dashboards, and post-mortem analyses to technical and non-technical management.
