Lead Cybersecurity WAF Engineer

The Lead Cybersecurity Web Application Firewall (WAF) Engineer is the enterprise's foremost expert and strategic owner of WAF and application-edge security. This role sets the vision, strategy, and standards that govern how public-facing applications are protected across Cox Automotive.

The Lead Engineer drives the architecture of WAF implementations, leads complex threat response efforts, advances automation and logging capabilities, and partners with cross-functional engineering, cybersecurity, and business teams to ensure resilient, scalable, and modern WAF protections. Main responsibilities are tuning and improving security policies, implementing the WAF for new public websites based on established architecture patterns, and participating in security events to use the WAF as a protective and defensive measure against threat actors.

This role will use their technical knowledge in implementing and using a web application firewall as a protective and defensive cybersecurity control. They will use their experience with networking concepts such as DNS, HTTP/S, and edge services to route website traffic, understand how web applications and mobile applications are designed to use client-server communication, and must be able to partner with cross-functional teams throughout the organization.

This role will report directly to the Senior Manager of Application Security at Cox Automotive.
