• Monitor network performance and ensure high availability and uptime
• Apply patches, firmware updates, and maintain hardware inventory
• Plan and execute network changes via formal change control processes

• Manage cloud networking on AWS VPC, Azure Virtual Network, and Google Cloud
• Oversee SD-WAN deployment and cloud-based SaaS integration
• Ensure reliable, secure connectivity for remote and distributed workforce
• Support hybrid cloud environments across on‑prem and cloud‑hosted workloads
• Configure and optimize cloud‑native firewall and network access policies

• Implement and maintain Zero Trust Network Access (ZTNA) policies
• Manage firewall rules, IDS/IPS, and network access control (NAC) systems
• Conduct regular vulnerability assessments and patch management cycles
• Monitor for threats using SIEM tools; coordinate incident response
• Enforce SASE (Secure Access Service Edge) frameworks for distributed users
• Support compliance with ISO 27001, NIST, SOC 2, and GDPR requirements

• Deploy and manage network monitoring tools (Solar Winds, Datadog, Grafana)
• Perform proactive capacity planning and bandwidth trend analysis
• Use AIOps platforms for predictive fault detection and auto‑remediation
• Maintain network documentation, diagrams, and configuration baselines (CMDB)
• Generate weekly/monthly SLA and performance reports for stakeholders

• Act as the first responder for network incidents (P1/P2 SLA adherence)
• Conduct root cause analysis (RCA) and post‑incident reviews
• Maintain and test disaster recovery and business continuity plans
• Collaborate with NOC, SOC, and service desk for end‑to‑end incident resolution
• Document known errors and workarounds in the knowledge base

• Routing & Switching: BGP, OSPF, EIGRP, STP, VLANs, QoS
• Firewall & VPN:
  Palo Alto, Fortinet, Cisco ASA, IPSec, SSL VPN
• Cloud Networking: AWS / Azure / GCP networking fundamentals
• Scripting & Automation:
  Python, Power Shell, Bash, Ansible, Terraform
• Wireless:
  Wi‑Fi 6/6E, controller management, site surveys
• Monitoring & Logging: SNMP, Net Flow, Syslog, SIEM integration
• Security Frameworks:
  Zero Trust, NIST CSF, ISO 27001, SOC 2
• ITSM: ITIL v4, Service Now, change & incident management

• Analytical Thinking:
  Diagnose complex, multi‑layer network issues quickly
• Communication:
