• Performance Monitoring & Optimization: Monitor network health and uptime using enterprise tools (PRTG, SolarWinds, Zabbix); troubleshoot complex network issues, and perform root cause analysis (RCA) using packet capture tools (Wireshark, TCPdump).
• Data Center & Cloud Integration: Maintain data center network infrastructure, redundancy solutions, virtualization platforms (VMware, Hyper-V), and hybrid/cloud connectivity (Azure/AWS).
• Vendor & ISP Management: Coordinate directly with Internet Service Providers (ISPs) and hardware vendors for link delivery, technical support, and SLA compliance.
• Documentation & Team Mentorship: Create and update network architecture diagrams, SOPs, and disaster recovery plans; mentor junior network engineers and support on-call emergency resolutions.

Requirements

• Education: Bachelor’s degree in Computer Science, Information Technology, Computer Engineering, or a related field.
• Experience: 5 to 8+ years of hands‑on experience in enterprise network administration and engineering.
