Job Title: F5 BIG-IP Engineer.
Location: Germany
Work Mode: Hybrid
Contract: 6 Months with possible extension.
Job Description We are looking for an F5 BIG-IP Engineer to design, deploy, and support enterprise load balancing, application delivery, and security infrastructure. This role focuses on hands-on BIG-IP administration, networking, and firewall/security concepts, with strong day-to-day operational ownership of LTM, GTM/DNS, and ASM/AWAF environments. Exposure to automation (Terraform/Ansible) is a plus but not the primary focus of this role.
Responsibilities
· Design, configure, and maintain F5 BIG-IP LTM (load balancing, virtual servers, pools, monitors, iRules, SSL profiles).
· Administer GTM/DNS for global traffic management and failover.
· Configure and tune ASM/AWAF policies for application security and WAF protection.
· Support network architecture including routing, VLANs, firewall rules, NAT, and traffic flow troubleshooting end-to-end (client → VIP → pool member).
· Manage F5 Virtual Editions (VE) in cloud environments (GCP/Azure) and/or on-prem hardware.
· Collaborate with network and security teams on firewall policy, segmentation, and traffic inspection requirements.
· Troubleshoot performance, connectivity, and SSL/TLS issues across application delivery paths.
· Participate in change management, maintenance windows, and on-call support for production BIG-IP environments.
· Document configurations, runbooks, and standard operating procedures.
· Where applicable, contribute to or support automation of BIG-IP configs using Ansible/Terraform.
Required Skills
· Hands-on production experience administering F5 BIG-IP (LTM required; GTM/DNS and ASM/AWAF strongly preferred).
· Solid networking fundamentals: TCP/IP, routing, VLANs, load balancing concepts, SSL/TLS.
· Firewall and network security concepts (NAT, ACLs, segmentation, traffic inspection).
· Experience troubleshooting application traffic paths and diagnosing connectivity/performance issues.
· Familiarity with iRules and BIG-IP configuration objects (virtual servers, pools, monitors, profiles).
· Experience working in cloud environments (GCP and/or Azure) with F5 Virtual Editions.
· Strong troubleshooting, documentation, and cross-team collaboration skills.
Nice to Have
· Working knowledge of Terraform and/or Ansible for BIG-IP automation.
· Familiarity with AS3, DO, or iControl REST APIs.
· F5 certification (F5-CA, F5-CTS, or equivalent).
· Experience with Splunk or cloud-native observability/logging tools.
· Exposure to CI/CD tools (GitHub Actions, GitLab CI, Jenkins).
· Scripting experience (Bash/Python).
