• Application Delivery: F5 load balancers (virtual servers, pools, health monitors, SSL/TLS profiles).
• Diagnostic & Tools: Ping, Traceroute, nslookup, iperf, traffic analysis, and DNS/AD/Storage service mapping.

Qualifications & Soft Skills

• Experience: At least 3 years of hands-on experience in network engineering, network operations, or a similar enterprise infrastructure role.
• Problem Solving: Data-driven troubleshooting approach with strong cognitive flexibility across enterprise infrastructure ecosystems.
