Your Role in Our Mission

How You’ll Make an Impact

  • Own the Cloudflare security stack: WAF, DDoS protection, Bot Management, Rate Limiting, API Shield, and Zero Trust (Access, Gateway, WARP)
  • Configure, test, and tune WAF custom rules and managed rulesets to protect both frontend and backend systems, cutting false positives and blocking emerging threats
  • Keep internal tools, including OKR and other dashboards, off the public internet by enforcing Zero Trust Access policies and verifying they are not externally reachable
  • Manage DNS, SSL/TLS, caching, Page Rules, Workers, and Load Balancing for performance and resilience
  • Monitor web traffic metrics, analyse logs (Cloudflare Logpush to SIEM), and investigate anomalies and attacks
  • Build and maintain automated alerting for traffic spikes, attack patterns, and misconfigurations, and mitigate issues before they affect traders
  • Respond to DDoS and bot incidents; document runbooks and drive post-incident improvements
  • Administer perimeter and internal firewalls and network segmentation across cloud and on-prem environments
  • Maintain firewall rule hygiene, change control, and periodic access reviews
  • Automate configuration with Terraform/IaC and the Cloudflare API
  • Partner with SRE, DevSecOps, and Engineering to secure new services before launch

What You Bring

  • 4+ years in network or firewall security, including 2+ years of hands-on Cloudflare experience
  • Strong WAF rule-writing and traffic/log analysis skills
  • Solid grasp of TCP/IP, DNS, HTTP/S, TLS, BGP basics, VPNs, and zero trust
  • Experience with enterprise firewalls (e.g., Palo Alto, Fortinet, pfSense) and cloud security groups/NACLs
  • Scripting and automation skills (Python, Bash) and IaC (Terraform preferred)
  • Familiarity with SIEM tools, monitoring/alerting setups, and incident response workflows

Nice to Have
