Your future duties and responsibilities
CGI is seeking a Senior F5 Network Engineer with deep, hands-on expertise in F5 BIG IP LTM and GTM/DNS to support a large scale, highly available financial services environment. F5 is the primary technology for this position, and candidates must have significant recent experience managing, troubleshooting, upgrading, and optimizing complex enterprise F5 environments.
This is a senior level engineering role focused on the F5 load balancing and application delivery infrastructure, including physical and virtual F5 platforms. The engineer will support infrastructure modernization, F5 platform replacements, configuration migrations, upgrades, patching, security hardening, capacity planning, and performance optimization.
The engineer will also serve as a senior escalation point for complex F5 and network related production issues, performing root cause analysis and independently driving issues through resolution. The position requires someone who can evaluate existing F5 configurations, identify opportunities for improvement, recommend technical changes, and successfully implement those changes in production.
In addition to F5, the environment includes Palo Alto firewalls, Cisco networking, Terraform automation, and AWS cloud networking technologies. Experience with these technologies is valuable, but the strongest candidates will distinguish themselves through their depth of F5 LTM and GTM/DNS experience.
The role will also contribute to Infrastructure as Code and automation initiatives, particularly using Terraform to manage and deploy F5 configurations. As a senior member of the team, the engineer will provide technical guidance to other engineers, document changes and implementation procedures, and contribute to the continued modernization of the network security perimeter.
Some complex production changes may be scheduled during after-hours maintenance windows.
