This role sits within the Cyber Security Technology group and is focused on designing, deploying, operating, and tuning enterprise Web Application Firewall (WAF) controls including F5 ASM/AWAF and Akamai Kona. The engineer will partner closely with security, network, cloud, and application teams to ensure secure, reliable, and compliant web application delivery across our financial client’’s environment., * Operate, monitor, and support enterprise web application firewalls (F5 ASM/AWAF and Akamai Kona) across multiple environments.

• Perform advanced troubleshooting of WAF-related issues, including analysis of HTTP/S traffic, WAF logs, and backend application behavior.
• Design, implement, and tune WAF policies and rules to mitigate OWASP Top 10 vulnerabilities, bot attacks, and other application-layer threats while minimizing false positives.
• Support architecture and engineering activities for WAF and broader web security solutions, including new applications, APIs, and security projects.
• Conduct regular health checks, capacity reviews, and user activity audits for WAF and related security infrastructure.
• Analyze security and application logs, identify attack patterns, and implement proactive rule updates or signatures.
• Collaborate with application developers, DevOps, and cloud teams to integrate WAF controls into application delivery pipelines and support secure coding practices.
• Create and maintain detailed documentation, including design diagrams, standards, runbooks, and operational procedures.
• Participate in incident response for web application and API security events, including triage, containment, and post-incident review.
• Contribute to automation initiatives for WAF configuration, deployments, and reporting using scripting and APIs.
• Potentially support and cross-train on adjacent network security technologies such as traditional firewalls, Network Access Control (NAC), load balancers, and DDoS protection.

• 5-8+ years of experience deploying and operating enterprise Web Application Firewalls in large, complex environments.
• Hands-on expertise with at least two of the following: Akamai Kona, F5 ASM/AWAF, Salt API Protection (or equivalent API protection solution).
• Strong understanding of web technologies and protocols, including HTTP/S, TLS, cookies, headers, REST APIs, and common authentication mechanisms.
• Solid knowledge of application-layer security fundamentals and common vulnerabilities (e.g., OWASP Top 10, bot and scraper attacks, API abuse).
• Proficiency in troubleshooting web and network issues using packet captures (e.g., tcpdump, Wireshark), CLI tools, and HTTP debugging tools.
• Experience analyzing application and WAF logs, correlating with backend services, and working directly with developers to resolve security and functionality issues.
• Bachelor’’s degree in Information Systems, Computer Science, Cybersecurity, or related field, or equivalent experience.
• Excellent written and verbal communication skills, with the ability to explain complex technical issues to non-technical stakeholders.
• Demonstrated customer-focused mindset, with experience managing expectations and building long-term relationships with business and technology partners.
• Willingness to work a flexible schedule, including on-call rotation for incident resolution.

Preferred / Nice-to-Have Skills

• Experience with API security and Web Application & API Protection (WAAP), including rate limiting, schema validation, and JWT/OAuth-aware policies.
• Familiarity with cloud platforms (AWS, Azure, Google Cloud Platform) and integrating WAF/WAAP solutions with cloud-native load balancers, CDNs, and ingress controllers.
• Scripting or coding skills (Python, PowerShell, or similar) for automation, reporting, and integration with CI/CD pipelines.
• Experience with Infrastructure-as-Code and configuration management tools (e.g., Terraform, Ansible) for security configuration management.
• Understanding of broader network security technologies (NAC, firewalls, proxies, DDoS mitigation, DNS security).
• Background in regulated environments (e.g., financial services) and familiarity with relevant compliance and risk management practices.
• Relevant security certifications (e.g., GWAPT, GWEB, CISSP, vendor-specific F5 or Akamai credentials).
