Job description

Role Overview

As a Senior F5 Engineer, you will lead the architecture, engineering, and migration of complex application delivery solutions. The primary focus of this role is the large-scale migration of legacy Citrix NetScaler environments to F5 BIG-IP (LTM/GTM). You will be responsible for the full lifecycle of the project, from initial data gathering and High-Level Design (HLD) to hands-on implementation and post-migration troubleshooting.

Key Responsibilities

  • Design & Architecture: Develop High-Level (HLD) and Low-Level Designs (LLD) for F5 LTM and GTM/DNS infrastructure across multi-site data centers.

  • NetScaler to F5 Migration: Lead the technical conversion of NetScaler configurations (Virtual Servers, Service Groups, Policies) into F5 BIG-IP equivalents (VIPs, Pools, iRules).

  • Traffic Management: Design and implement intelligent traffic steering using F5 GTM (Global Traffic Manager)and complex load balancing logic via LTM (Local Traffic Manager).

  • Programmability: Write, test, and deploy advanced iRules (TCL-based) to handle header manipulation, URI switching, and custom persistence requirements that were previously handled by NetScaler policies.

  • Lifecycle Management: Manage F5 hardware/virtual platforms (Viprion, iSeries, or rSeries) and perform OS upgrades, licensing, and vCMP guest provisioning.

  • Security Integration: Configure SSL offloading, certificate management, and basic security profiles (WAF/ASM integration is a plus).

  • Stakeholder Collaboration: Work with application owners to understand traffic flows and requirements, ensuring zero-downtime migrations through meticulous cutover planning.

Technical Skills & Qualifications1. Core F5 Expertise

  • F5 BIG-IP LTM: Expert knowledge of Profiles (TCP, HTTP, SSL), Persistence (Cookie, Source-IP), Monitors, and SNAT.

  • F5 BIG-IP GTM/DNS: Experience with Wide-IPs, Distributed Cloud/Global Server Load Balancing (GSLB), and iQuery communication.

  • iRules Development: Proficiency in writing custom scripts to solve complex traffic steering challenges.

  • Platform Mastery: Hands-on experience with vCMP (Virtual Clustered Multiprocessing) and high-availability (HA) failover clusters.

2. Migration Specifics

  • NetScaler Proficiency: Strong understanding of Citrix ADC/NetScaler concepts (Content Switching, Responder/Rewrite policies, AppExpert) to effectively map them to F5.

  • Migration Tools: Familiarity with manual conversion methods or automation scripts (Python/Ansible) to expedite configuration porting.

3. Network & Troubleshooting

  • Protocol Depth: Deep understanding of the OSI model, specifically TCP/IP, HTTP/S, DNS, and SSL/TLS.

  • Tools: Expert-level use of Tcpdump, Wireshark, and F5's internal bash and tmsh shells for deep packet analysis.

Experience & Education

  • Experience: 6-8 years in Network Engineering, with at least 4+ years dedicated strictly to F5/ADC technologies.

  • Proven Track Record: At least one major migration project (NetScaler to F5 or vice-versa) successfully delivered.

  • Certifications: F5 Certified Technology Specialist (LTM/GTM) or F5 Certified Solution Expert (preferred).

Soft Skills

  • Analytical Thinking: Ability to decompose complex legacy NetScaler policies into clean, efficient F5 logic.

  • Communication: Able to explain technical migration risks to non-technical business stakeholders.

  • Project Leadership: Experience leading technical workstreams within a larger infrastructure transformation program.
