Job details:
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.
