Review, analyze, and execute network change requests.

Ability to optimize firewall rule bases and troubleshoot complex traffic flows.
Hands-on experience with F5 BIG-IP (LTM required; GTM preferred).
Experience in: VIPs, pools, health monitors. Persistence, SSL offloading. Performance tuning and capacity planning. Supporting high-traffic production applications. Experience integrating F5 with data center or cloud workloads
Enterprise / Large-Scale Experience:
Data center buildouts or expansions Major network migrations (DC refresh, firewall migration, LB migration) Large enterprise networks (hundreds/thousands of users, multi-site) High-availability, 24 7 production environments
Strong understanding of BGP, OSPF (MPLS is a plus). Experience with:
