We are seeking an experienced CDN & Edge Infrastructure Engineer to lead the migration and refactoring of CDN and edge infrastructure from AWS (CloudFront, WAF, Lambda@Edge) to Cloudflare CDN, WAF, and Edge Functions using Infrastructure-as-Code (IaC) principles.
You will architect, implement, and optimize global content delivery and edge security infrastructure that supports Smart TV and Mobile Cloud backends, ensuring high availability, security, and performance across multiple regions.
This role demands deep knowledge of IaC refactoring, CDN performance engineering, and DNS orchestration using Cloudflare’s developer ecosystem.
Key Responsibilities:
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.
