    • Troubleshoot connectivity issues (policy, routing, NAT, sessions, logs)

    • Maintain network diagrams, IP addressing plans, and topology visibility

    Monitoring & Continuous Improvement (Zabbix)

    • Own Zabbix monitoring for network devices and key services
    • Improve alert quality (reduce noise/false alerts, meaningful thresholds)
    • Build dashboards and monthly KPI reports (uptime, top incidents, root causes)
    • Implement proactive monitoring for links, VPN health, and device performance

    Windows & Linux Troubleshooting (Required)

    • Troubleshoot end‑to‑end issues involving OS + network (DNS, DHCP, auth, routing)
