- 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.

- Experience: 5 to 8+ years of hands-on experience in enterprise network administration and engineering.
- Core Technical Expertise: In-depth knowledge of TCP/IP, VLANs, STP, OSPF, BGP, HSRP/VRRP, NAT, QoS, DNS, and DHCP.
- Vendor Hardware Proficiency: Hands-on experience with Cisco, Fortinet, Sangfor, Aruba/HP, Juniper, MikroTik, or similar enterprise networking gear.
Nice to have

- Familiarity with project management frameworks (PMP or PRINCE2).
- Direct experience engineering network infrastructure in warehousing, logistics, or multi-site 3PL operations.
