• Manage Akamai WAF/Kona, Cloudflare WAF, bot management, rate limiting, IP firewall, and DDoS protection.
• Tune security rulesets (OWASP signatures, custom rules, API schema validation, bot scoring, ACLs).
• Respond to security alerts, block malicious traffic, and coordinate with SOC for edge attack investigations. Application Load Balancing & Origin Management
• Manage ALB at cloud (Azure/OCI/AWS ALB), on prem ADCs, or CDN-based L7 load balancers.
• Handle end to end traffic flow from CDN ? Load Balancer ? Reverse Proxy ? Application Servers.
• Maintain and optimize origin server configurations: SSL/TLS policies, caching headers, security headers (HSTS, CSP), keep-alive settings. Network & Ingress Traffic Management
• Implement DNAT, reverse proxy routing, path/host-based routing, and micro segmentation at ingress.
• Ensure secure transport via mTLS, TLS 1.2/1.3, certificate lifecycle, OCSP stapling, key rotation.
• Troubleshoot traffic issues using HTTP traces, HAR logs, CDN debug headers, edge logs, and packet captures. Monitoring & Incident Management
• Monitor CDN/WAF performance, DNS health, origin latency, and traffic anomalies.
• Handle 24×7 operational incidents, CDN failover, WAF rule lockdowns, and DNS routing changes.
• Provide RCA (root cause analysis) and implement long term remediation. Documentation & Collaboration
• Maintain documentation for CDN architectures, DNS routing, WAF rules, security policies, and SOPs.
• Collaborate with application teams, security teams, DevOps, SRE, and product owners for stable releases and go lives.|B. Additional Accountabilities (Advanced / Growth-Oriented) Architecture & Optimization
• Design and enhance Multi CDN & Multi DNS strategies for high availability, performance, and global coverage.
• Implement smart routing logic using Akamai Property Manager, Cloudflare Workers, Transform Rules, and Edge Logic.
• Lead optimization for web performance (LCP, FID, CLS) using CDN improvements and origin tuning. Security Leadership
• Build zero trust edge security policies including API security, bot management, behavioural detection, and micro segmented WAF rules.
• Periodically test security posture against DDoS, WAF bypass, and bot attacks.
• Work with SOC to integrate CDN logs with SIEM. Automation & DevSecOps
• Automate CDN config deployments using Terraform, Akamai APIs, Cloudflare API, CI/CD workflows.
• Build scripts for DNS failover checks, certificate renewals, and edge rule validations.
• Maintain version-controlled configuration repositories. Performance Engineering
• Drive improvements in latency, TTFB, cache hit ratio, origin offload, and bandwidth cost optimization.
• Perform load tests and chaos testing for CDN failover scenarios. Leadership & Governance
• Be the L3 escalation point for CDN/DNS/WAF/security issues.
• Guide junior engineers and partner teams on best practices.
• Own change governance for CDN, DNS, and security policies across environments. ________________________________________

Key Decisions / Dimensions

• Approve CDN cache/waf rule changes, routing policies, DNS steering logic.
• Decide on emergency CDN failover or WAF lockdown actions during attacks.
• Recommend performance optimizations and security enhancements.
• Determine routing strategies for multi cloud and multi edge traffic. ________________________________________

Major Challenges

• Maintaining consistent behavior across multiple CDNs, DNS providers, and WAF engines.
• Balancing performance vs. security across global user bases.
• Managing rapid application changes with tight SLAs and zero-downtime deployments.
• Protecting APIs and web workloads from evolving bot/DDoS attacks.
• Ensuring fault-tolerant traffic management across CDN ? DNS ? LB ? origin. ________________________________________
