Your Role in Our Mission

You will secure the network edge. You will design, run, and tune our Cloudflare and firewall infrastructure so legitimate traders get seamless access and attackers get none.

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
