CDN & Edge Infrastructure Engineer

CDN & Edge Migration

• Lead
  the refactoring of AWS CloudFront-based IaC (Terraform, CloudFormation)
  into Cloudflare IaC modules using Terraform or Wrangler.


• Migrate
  and optimize AWS CloudFront distributions to Cloudflare CDN with
  equivalent or improved caching, compression, and SSL/TLS configurations.


• Recreate
  and enhance AWS WAF rules in Cloudflare WAF, ensuring parity for rate
  limits, geo-blocking, and custom rule groups via Terraform.


• Translate
  and deploy AWS Lambda Edge functions into Cloudflare Workers / Edge
  Functions, ensuring functional equivalence and latency improvements.


• Validate
  edge routing, caching, and security behavior post-migration using
  synthetic and load testing tools.

Infrastructure-as-Code (IaC) & Automation

• Maintain
  all configurations in Git-based IaC repositories with full CI/CD
  automation for deployments.


• Develop
  reusable Terraform modules for Cloudflare CDN, WAF & DNS zones.


• Implement
  environment-based configuration (Dev, Stage, Prod) with variable
  management, tagging, and policy enforcement.


• Integrate
  IaC validation, linting, and compliance checks (e.g., Sentinel or OPA)
  into pipelines.

DNS & Traffic Management

• Establish
  and manage DNS Hosted Zones in Cloudflare, including domain delegation,
  CNAME/ALIAS flattening, and traffic routing policies.


• Implement
  Geo-DNS and failover routing for critical Smart TV and mobile backend
  endpoints.


• Automate
  DNS record management and zone imports using Cloudflare Terraform
  Provider.


• Migrate
  existing Route53 records and health checks into Cloudflare equivalents
  with rollback safety.

Performance, Security & Observability

• Tune
  CDN caching policies (cache keys, TTLs, origin shielding) to optimize
  global performance.


• Integrate
  Cloudflare WAF, Bot Management, and Page Rules to ensure secure delivery
  of APIs and content endpoints.


• Configure
  Real User Monitoring (RUM) and Cloudflare Analytics dashboards for
  performance visibility.


• Implement
  Zero Trust principles (Access, Gateway, and DLP) for edge security
  enforcement.

Collaboration & Delivery

• Collaborate
  with DevOps, backend, and application teams to align CDN behavior with app
  logic and API routing.


• Document
  migration processes, edge routing flows, and IaC module usage.


• Conduct
  knowledge transfer sessions for operational and support teams'
  post-migration.
