• Configure and maintain reverse proxy and application publishing patterns for internet-facing services across cloud and hybrid environments
• Develop, tune, and maintain WAF policies and custom rules to protect against application-layer threats while minimizing false positives
• Analyze and mitigate malicious traffic patterns, including DDoS attacks, bot activity, and common web application exploits
• Apply edge-based traffic management strategies, including traffic steering, failover, and performance optimization across geographic regions
• Optimize application performance, availability, and resiliency through caching strategies, load distribution, and edge control capabilities
• Deploy and manage edge platform configurations
• Automate configuration, policy enforcement, and lifecycle management
• Troubleshoot application delivery issues, including latency, connectivity, TLS/certificate errors, and WAF rule conflicts
• Perform traffic analysis using logs, metrics, and packet capture tools to investigate and resolve production issues
• Partner with security, cloud, and application teams to implement and enforce secure design patterns aligned with modern web security standards (e.g., OWASP Top 10)
• Contribute to monitoring and alerting strategies to proactively detect and respond to performance or security issues at the edge
• Create and maintain documentation for configurations, standards, and operational procedures to support scalable service delivery

• Experience with Infrastructure as Code tools and Git-based version control workflows
• Familiarity with API-driven automation and CI/CD pipelines for infrastructure or platform delivery
• Foundational knowledge of networking concepts, including TCP/IP, routing fundamentals, and cloud/hybrid connectivity models
• Hands-on experience troubleshooting network and application delivery issues using logs, metrics, and packet analysis tools (e.g., Wireshark, tcpdump)
• Experience working in cloud environments (AWS, Azure, or GCP) and supporting hybrid application deployments
• Strong problem-solving skills with the ability to analyze complex technical issues and drive resolution
• Effective communication skills with the ability to collaborate across engineering, security, and application teams
  
  
  

What Will Put You Ahead

• 7+ years of experience in either support of complex enterprise networks, or management of network security devices like firewalls, proxies, reverse proxies and IPS devices
• Knowledge on the Palo Alto NGFW’s, ZScaler – ZIA, ZPA, ZBA FortiGate firewalls and Cloudflare.
