Cloudflare Security Engineer (WAF / WARP) - Contract (3 Months) We're looking for a highly confident, hands-on Cloudflare Security Engineer to lead a critical migration from AWS WAF to Cloudflare WAF. This is a fast-paced, technically demanding engagement where deep expertise in Cloudflare WARP and Terraform-led infrastructure automation is essential. This role requires someone who can own complex security challenges end-to-end, operate with minimal oversight, and make confident decisions in high-impact environments. This is a fully remote contract that will initially start as a 3-month contract. Key Responsibilities

  • Lead the end-to-end migration from AWS WAF to Cloudflare WAF (rule translation, optimisation, testing, rollout)
  • Design and implement Cloudflare WAF policies (managed rules, custom rules, bot protection, rate limiting)
  • Deploy and manage Cloudflare Zero Trust & WARP for secure, identity-based access
  • Configure and optimise DNS, load balancing, and traffic steering within Cloudflare
  • Integrate Cloudflare with AWS services (ALB, CloudFront, Route 53)
  • Implement edge security controls (DDoS protection, TLS, monitoring)
  • Troubleshoot complex networking, performance, and security issues
  • Support scalable deployments using Terraform

Requirements

  • Extensive hands-on experience with Cloudflare WAF, Zero Trust, and WARP (non-negotiable)

  • Proven track record migrating from AWS WAF to Cloudflare

  • Strong understanding of DNS, TLS, CDNs, reverse proxies, and traffic routing

  • Solid AWS background (ALB, CloudFront, Route 53, security services)

  • Strong experience with Terraform

  • Excellent problem-solving skills across security and network layers Key Traits

  • Confident and decisive in high-pressure security scenarios

  • Able to navigate ambiguity and complex edge cases

  • Strong ownership mindset with a hands-on approach If you're a Cloudflare specialist who thrives on complex security challenges and large-scale migrations, this is a high-impact opportunity to make a tangible difference quickly, and we would love to hear from you!
