Note: The job is a remote job and is open to candidates in USA. IS3 Solutions is seeking a Senior F5 Load Balancing Engineer to support a client engagement with an enterprise financial services client. The role involves migrating from Citrix NetScaler to the F5 platform and delivering infrastructure changes primarily through automation.
Responsibilities
- Support the ongoing migration from Citrix NetScaler to F5 (BIG-IP Next or equivalent target platform), including configuration conversion, testing, and cutover activities
- Maintain and troubleshoot the remaining legacy NetScaler environment during the transition period
- Deliver infrastructure changes primarily through automation — Ansible and Terraform — rather than manual configuration; build and maintain automation code for provisioning and lifecycle management
- Configure and support F5 load balancing services (LTM and related modules) for enterprise application delivery
- Apply core networking protocol knowledge (routing, VLANs/trunking, DNS) to design and troubleshoot traffic flows across the load balancing layer
- Partner with network, security, and application teams to translate requirements into load balancing and automation solutions
- Troubleshoot issues related to load balancing, SSL/TLS offload, application performance, and traffic routing
- Support change management, documentation, and operational runbooks in accordance with banking/financial industry compliance standards
- Collaborate with the M&T Bank client team and WWT delivery leads to ensure solutions align with security, availability, and regulatory requirements
Skills
- Strong hands-on automation experience with Ansible and Terraform
- Solid networking fundamentals (routing/switching, VLANs, DNS, SSL/TLS)
- Comfort picking up load balancing concepts quickly; prior F5 BIG-IP or Citrix NetScaler exposure is a plus but not required
- Experience working in large enterprise or regulated environments (financial services preferred)
- Solid troubleshooting skills across network, security, and application layers
- Ability to communicate effectively with both technical teams and business stakeholders
- Direct hands-on experience with F5 BIG-IP (LTM, GTM/DNS, ASM/Advanced WAF, APM) and/or F5 BIG-IP Next
- Prior experience with Citrix NetScaler, particularly NetScaler-to-F5 migrations
- F5 certifications (F5-CA, F5-CTS, or F5-CE) or networking certifications (CCNP, CCIE, or equivalent)
- Experience with CI/CD pipelines and infrastructure-as-code practices beyond Ansible/Terraform basics
- Familiarity with Kubernetes/containerized environments (relevant if the target platform is BIG-IP Next)
- Prior experience supporting banking, financial services, or other highly regulated clients
