• 10+ years of relevant experience in network security, application security, infrastructure engineering, or related technical roles, with substantial hands-on WAF experience.
• Strong hands-on experience configuring, migrating, and supporting enterprise WAF technologies, ideally Cloudflare and/or Akamai.
• Practical knowledge of DNS, HTTP/HTTPS, TLS, traffic routing, application delivery, and web security concepts.
• Experience implementing and tuning WAF policies and security rules, troubleshooting application traffic, and resolving migration or production issues.
• Demonstrated experience working collaboratively with architecture, security, network, and application teams to deliver complex technical changes.

Bonus Points For
