Perform testing, troubleshooting, and validation to confirm functionality, security, and performance throughout migration waves.

Partner with architecture, security, network, and application teams to support cutover activities, resolve technical issues, and stabilize services following migration.

What We’re Looking For

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

Knowledge of Cloudflare and Akamai security, application delivery, and traffic management capabilities.
