Manage firewall and perimeter security appliances (Cisco ASA/FTD, Palo Alto, Fortinet) for rule changes, policy audits, NAT, VPN terminators, and support security operations to ensure network segmentation and compliance.
Provision, monitor, and troubleshoot remote access and VPN services (IPSec, SSL VPN, client VPN), ensuring secure connectivity for remote users and branch locations and enforcing multi‑factor authentication where applicable.
Perform network capacity planning and performance tuning, analyze historical usage, forecast growth, recommend upgrades or architecture changes, and support budgeting for network expansions.
Maintain load balancers and application delivery controllers (F5, Citrix ADC), including health checks, pool configuration, SSL offloading, and troubleshooting application connectivity or session issues.
Execute scheduled maintenance windows and coordinated change management activities; prepare rollback plans, update configuration management databases, and ensure minimal service disruption.
Support and maintain wireless LAN infrastructure (Cisco Meraki, Aruba, Ruckus), monitor RF performance, troubleshoot client connectivity issues, and assist with site surveys and capacity planning.
Manage IP address space, DHCP, DNS operations (Windows Server DNS, BIND, Infoblox), and keep network inventory and documentation current to reduce mean time to resolution.
Maintain and execute backup/restore procedures for network device configurations and ensure disaster recovery readiness for critical network elements.
Implement and maintain network monitoring alarms, synthetic transactions, and dashboards to proactively detect degradation, define thresholds, and reduce incident windows.
Automate recurring operational tasks using scripting (Python, Bash, PowerShell) and configuration management tools (Ansible, Terraform) to improve repeatability and reduce human error.
Enforce network change control policies and collaborate with security, compliance, and application teams to ensure changes meet governance and audit requirements.
Participate in on‑call rotations, respond to after‑hours incidents, and perform urgent troubleshooting and remediation under SLA constraints.
Coordinate vendor relationships and escalate hardware, software or service issues to vendors, manage RMA processes, and validate fixes or replacements.
Prepare operational runbooks, standard operating procedures (SOPs), topology diagrams, and knowledge base articles to enable efficient triage and handoffs across shifts.
Test and validate firmware and configuration changes in lab or staging environments before production deployment to reduce risk and avoid regressions.
Support VoIP and UC troubleshooting (SIP, RTP, QoS), ensuring voice quality and addressing jitter, latency, and packet loss issues impacting phone systems.
Support cloud networking tasks for hybrid environments (AWS VPC, Azure Virtual Network, GCP), including routing, peering, transit gateways, security groups and troubleshooting interconnectivity issues.
Monitor and enforce Quality of Service (QoS) policies across WAN and LAN to prioritize voice, video, and critical business applications and optimize user experience.
Participate in architecture and project teams to provide operational perspective for new network deployments, migrations, upgrades, and integrations.

Secondary Functions

Maintain and enhance the network documentation library, runbooks and topology diagrams for on‑call and project handover.
Provide Tier 2/3 escalation support for field technicians and junior NOC staff; mentor and train new team members on monitoring tools and escalation procedures.
Execute quarterly or annual capacity and resiliency reviews and present actionable findings to IT leadership for budgeting and roadmap planning.
Assist in vendor procurement evaluations, RFP responses, and technical comparisons to support purchasing decisions.
Lead or participate in disaster recovery and business continuity testing for network services, documenting outcomes and remediation plans.
Build and refine automation playbooks (Ansible, Python scripts) to reduce manual steps for common configuration changes and incident responses.
Generate recurring operational reports (uptime, incident trends, MTTR, capacity metrics) and produce insights that drive continuous improvement.
Support compliance activities (PCI, SOC2, HIPAA as applicable) by providing network logs, evidence of configuration control, and access reviews.
Facilitate cross‑team workshops with application owners, security, and infrastructure to align on SLAs, maintenance windows and deployment cadences.
Evaluate and pilot new network technologies (SDN, intent‑based networking, SASE) and provide recommendations based on operational readiness and ROI.
