Network- F5 Load Balancer

Architecture & Design
* Own the data center network reference architecture, covering core, aggregation, leaf-spine, DCI, and edge services.
* Design EVPN/VXLAN fabrics, multi pod/multi site architectures, and data center interconnects (e.g., OTV/EVPN DCI, MPLS, or SD-WAN underlays).
* Architect F5 BIG IP solutions for LTM (Local Traffic Manager), GTM/DNS, ASM/Advanced WAF, APM, and SSL offload/inspection.
* Define service insertion patterns for L4-L7 services (firewalls, IDS/IPS, WAF, DDoS, proxies) and app delivery pipelines.
* Establish resiliency/HA patterns, capacity models, and north-south / east-west traffic engineering strategies.
* Create standards for multi tenant segmentation (VRF, VRF-lite, micro segmentation, SGT/ACL models).
Implementation & Integration
* Lead deployments and migrations across data centers with minimal downtime; define cutover and rollback plans.
* Implement F5 iRules/iApps/AS3/DO for policy automation and standardized application onboarding.
* Integrate F5 with DNS/DHCP/IPAM (DDI), PKI, SIEM/SOAR, identity (LDAP/AD), and observability stacks.
* Implement TLS/SSL lifecycle management (ciphers, certificates, OCSP stapling, HSTS, PFS) and DDoS/WAF protections.
* Enable cloud connectivity and app delivery patterns (Transit Gateway, PrivateLink, Global Accelerator, or F5 Distributed Cloud) as needed.
Operations, Reliability & Security
* Establish operational SOPs/runbooks, observability KPIs, and proactive health checks.
* Drive lifecycle management: code upgrades, ISSU, patches, and vulnerability remediation across network and F5 platforms.
* Troubleshoot complex L2-L7 issues (BGP/ECMP/MLAG/EVPN, SSL/TLS, HTTP, TCP optimization, DNS/GSLB logic).
* Define network security architecture: segmentation, firewall policy zones, WAF policy baselines, and compliance controls.
Leadership & Governance
* Act as the SME/Architect of record for data center and application delivery.
* Lead design reviews, produce HLD/LLD, and mentor engineering/operations teams.
* Partner with application owners to translate non-functional requirements (NFRs) into scalable network and L7 designs.
* Contribute to budget planning, vendor selection, POCs, and roadmap development.

Looking for a seasoned Data Center Network Architect with deep expertise in F5 BIG-IP to architect, modernize, and secure large-scale, high-availability data center networks. You will lead the end-to-end design covering routing/switching, DC fabrics (EVPN/VXLAN), load balancing (LTM/GTM/DNS), security, automation, and hybrid connectivity (cloud and WAN). This role partners closely with infrastructure, cloud, security, and application teams to deliver resilient, scalable, and policy-driven architectures.
