Job description

Title- CDN & Edge Infrastructure Engineer

Location- Dallas, TX , 5 days onsite (Need locals)

Term : Contract

Role :

  • 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.
