Summary:

A typical day of a subject matter expert and as an accomplished Network Security / Firewall Engineer Team lead, your role demands to broad and deep expertise spanning next-generation firewall (NGFW) platforms, Web Application Firewall (WAF) technologies, and Zscaler cloud security services — unified under a cohesive Zero Trust security strategy.

As a Level 3 engineer, you will lead architectural decisions, drive security policy governance, own escalation for complex incidents, and mentor junior engineers. You will partner with application, cloud, and SOC teams to design and enforce security controls that protect the organization's network perimeter, web-facing applications, and distributed workforce — across on-premises, multi-cloud, and hybrid environments.

Roles & Responsibilities:

Expected to be an SME, collaborate and manage the team to perform.
Design, deploy, and manage enterprise NGFW platforms including Palo Alto Networks (PA-Series, VM-Series, Panorama), Fortinet FortiGate (FortiManager, FortiAnalyzer), Cisco ASA/FTD/Firepower, and/or Check Point Security Gateways.
Develop, review, and enforce firewall security policies — access control rules, NAT, application-layer filtering (App-ID), User-ID, and content inspection.
Deploy and administer enterprise WAF solutions including F5 BIG-IP ASM/AWAF, Imperva SecureSphere/Cloud WAF, AWS WAF, Azure Application Gateway WAF, and/or Cloudflare WAF.
Develop and maintain WAF security policies to protect web applications against OWASP Top 10 threats: SQL injection, XSS, CSRF, RFI/LFI, command injection, and bot attacks.
Lead the deployment and management of Zscaler Internet Access (ZIA) — including secure web gateway (SWG), SSL/TLS inspection, CASB, cloud sandbox, DLP, and advanced threat protection.
Administer Zscaler Private Access (ZPA) for zero-trust application access, replacing legacy VPN with identity-aware, least-privilege connectivity to internal and SaaS applications.
Manage ZPA App Connectors, App Segments, Connector Groups, and Broker-Based Access architecture for secure internal application publishing.
Configure and maintain Zscaler Digital Experience (ZDX) for end-user experience monitoring, application performance visibility, a- nd network path diagnostics.
Own the long-term security architecture roadmap for firewall, WAF, and cloud security platforms aligned with Zero Trust Network Access (ZTNA) principles.
Design integrated security architectures that unify perimeter NGFW enforcement, WAF application protection, and Zscaler cloud-based inspection in a cohesive layered model.
Lead network security design reviews for new projects, cloud migrations, and application deployments — ensuring security is embedded from inception.
Serve as the Level 3 escalation point for firewall, WAF, and Zscaler security incidents, policy violations, and network-layer attacks.
Investigate and respond to threats including DDoS attacks, web application exploitation, network intrusions, lateral movement, and data exfiltration attempts.
Analyze firewall traffic logs, WAF event logs, and Zscaler threat intelligence to identify attack campaigns and anomalous behavior.
Perform root cause analysis (RCA) for security incidents and produce actionable post-incident reports with remediation recommendations.

2+ years of hands-on Zscaler ZIA and ZPA administration in enterprise environments.
Demonstrated experience leading security operations or serving as a technical SME/escalation point.
Expert-level proficiency in at least two major NGFW platforms: Palo Alto Networks (PAN-OS, Panorama), Fortinet FortiGate (FortiOS, FortiManager), Cisco ASA/FTD, or Check Point.
Deep knowledge of firewall policy design: security zones, NAT, application control, User-ID, URL filtering, and HA configurations.
Hands-on experience administering WAF platforms: F5 BIG-IP ASM/AWAF, Imperva, AWS WAF, Azure Application Gateway WAF, and/or Cloudflare.
Strong understanding of OWASP Top 10, web application attack vectors, and WAF detection/prevention techniques.
Proficiency in Zscaler Admin Portal — ZIA and ZPA policy configuration, user/group management, and reporting.
Experience configuring GRE/IPsec tunnels, PAC files, and Zscaler Client Connector deployments.
Familiarity with ZPA App Connectors, Connector Groups, and zero-trust application access architecture.
Strong networking fundamentals: TCP/IP, BGP/OSPF, VLANs, spanning tree, DNS, HTTP/S, and TLS.
Scripting/automation skills: Python, PowerShell, Bash, or Ansible for firewall/WAF/API automation.
