• Configuring and maintaining routers, switches, firewalls, wireless controllers, access points, load balancers, and network appliances.
• Managing IP addressing, subnetting, VLANs, DHCP, DNS, NAT, routing, switching, and network segmentation.
• Monitoring network availability, bandwidth, latency, packet loss, utilization, and overall performance.
• Troubleshooting network outages, connectivity issues, routing problems, DNS failures, wireless problems, and performance degradation.
• Implementing firewall policies, VPN solutions, access controls, intrusion-prevention measures, and secure network architectures.
• Supporting cloud and hybrid networking environments across platforms such as AWS, Microsoft Azure, and Google Cloud.
• Managing connectivity between offices, data centers, cloud environments, remote locations, and external networks.
• Performing network upgrades, migrations, expansions, hardware replacements, and infrastructure improvements.
• Conducting network capacity planning and recommending improvements based on business and technical requirements.
• Developing network diagrams, architecture documentation, configuration standards, operating procedures, and technical records.
• Managing network configurations, firmware upgrades, patches, backups, licenses, and change-control processes.
• Conducting network assessments, vulnerability reviews, performance analysis, and security evaluations.
• Supporting network redundancy, disaster recovery, business continuity, and high-availability solutions.
• Implementing network monitoring, logging, alerting, and automated incident-detection systems.
• Using scripting, APIs, network automation, Infrastructure as Code, data analytics, and AI-assisted network-management tools where appropriate.
• Collaborating with cybersecurity, cloud, DevOps, systems, IT support, infrastructure, application, and business teams.
• Coordinating with internet service providers, telecommunications providers, vendors, and external technical specialists.
• Managing network incidents, service requests, escalations, and root-cause investigations.
• Maintaining network asset inventories, configuration records, licenses, support agreements, and technical documentation.
• Optimizing network performance, reliability, scalability, security, and operational costs.
• Supporting data-center deployments, office expansions, infrastructure projects, technology upgrades, and digital-transformation initiatives.
• Ensuring network infrastructure complies with organizational security policies, technical standards, and applicable requirements.
• Preparing network-performance reports, incident summaries, capacity assessments, risk reports, and technical recommendations.
• Providing technical guidance and support to network administrators, IT teams, and other technical stakeholders.
• Continuously improving network reliability, security, automation, scalability, performance, and operational efficiency.
