Job Summary The Senior Network Firewall Engineer plays a critical role in securing and enabling global enterprise connectivity across hybrid and multi-cloud environments, including AWS and Microsoft Azure. This position is responsible for the architecture, implementation, governance, and operational excellence of network security platforms supporting a highly distributed, 24x7 global business. This role serves as a senior technical authority for next-generation firewall services, cloud network security controls, and segmentation strategies across data centers, regional hubs, cloud landing zones, and remote access environments. A strong emphasis is placed on standardization, scalability, and visibility through centralized management platforms. The position requires deep hands-on expertise with Palo Alto Networks firewalls and Palo Alto Networks Panorama, including large-scale policy management, GlobalProtect remote access architecture, advanced threat prevention, and global firewall lifecycle management. The engineer will drive consistency and security posture improvements across multi-region environments through centralized governance and automation. Key Responsibilities Global Firewall & Network Security Architecture - Architect, design, and operate enterprise-scale firewall solutions across on-premises data centers and multi-cloud environments (AWS and Azure) - Lead global firewall strategy for hybrid connectivity, including cloud landing zones, shared services, and inter-region connectivity - Design and enforce network segmentation, zero trust principles, and least privilege access models at global scale - Architect and manage Palo Alto Networks Panorama for centralized policy management, device group hierarchy, and template-based configuration standardization - Design and implement scalable GlobalProtect VPN architectures, including multi-portal and multi-gateway deployments, HIP-based policy enforcement, and certificate-based authentication - Develop standardized firewall design patterns leveraging security zones, virtual routers, NAT policies, and policy-based forwarding (PBF) - Lead migration and consolidation of distributed firewall environments into centralized Panorama-managed platforms Cloud Security (AWS & Azure) - Implement and manage cloud-native and virtual firewall solutions within AWS and Azure environments - Partner with Cloud Platform teams to integrate network security services into cloud adoption frameworks and landing zones - Secure site-to-site, inter-VPC/VNet, and hybrid connectivity (VPN, ExpressRoute, Direct Connect) - Extend enterprise firewall policies and segmentation strategies consistently into cloud environments - Support automated, policy-driven firewall deployments using infrastructure-as-code and CI/CD pipelines Operations, Reliability & Incident Management - Provide Tier 3 / Tier 4 operational support for firewall and perimeter security services across global environments - Lead troubleshooting and root cause analysis of complex, multi-region network security incidents - Perform advanced diagnostics using packet capture, session flow analysis, and traffic logging within Palo Alto platforms - Troubleshoot and resolve issues involving NAT, VPN (IPsec and GlobalProtect), routing (BGP/OSPF), asymmetric traffic, and application-layer behavior - Leverage Panorama for centralized visibility, log aggregation, and rapid incident response - Ensure firewall platforms meet enterprise SLAs for availability, resiliency, and performance - Participate in a global on-call rotation supporting 24x7 business operations Governance, Risk & Compliance - Ensure firewall policies and network security controls align with global security standards and regulatory requirements (PCI DSS, SOX, ISO 27001, NIST) - Enforce standardized security policies globally using Panorama device groups and templates - Drive policy lifecycle management, including rule optimization, cleanup, and audit readiness - Leverage advanced firewall capabilities such as App-ID, User-ID, and Content-ID to enforce identity-aware, application-based security controls - Support internal and external audits, risk assessments, and compliance initiatives - Partner with Information Security, Risk, and Compliance teams to continuously improve the enterprise security posture Automation, Tooling & Continuous Improvement - Improve firewall operations through automation, standardization, and platform optimization - Automate firewall provisioning and policy management using Panorama APIs, scripting, and infrastructure-as-code tools (Python, Terraform, ARM/Bicep) - Integrate firewall configurations into CI/CD pipelines to reduce manual effort and configuration drift - Develop reporting and analytics leveraging Panorama logs and external platforms such as SIEM tools - Evaluate emerging network security technologies and recommend enterprise adoption strategies Leadership & Collaboration - Act as a senior technical mentor and escalation point for regional network and security engineering teams - Lead large-scale firewall lifecycle initiatives, including global hardware refresh programs, pre-staging, and coordinated multi-site deployments - Collaborate with Cloud Engineering, Security Operations, Infrastructure, and Application teams - Influence architectural decisions through design reviews and technical governance forums - Operate effectively in environments with varying levels of local technical support, executing remote deployments and migrations where required Required Qualifications - Bachelor’s degree in Computer Science, Information Technology, Cybersecurity, or equivalent experience - 8+ years of enterprise network engineering experience with a strong focus on firewall and network security - Deep hands-on experience with Palo Alto Networks firewalls and Palo Alto Networks Panorama in large-scale, globally distributed environments - Strong knowledge of TCP/IP, routing, switching, VPNs, segmentation, and traffic inspection at scale - Proven experience supporting hybrid and multi-cloud enterprise networks Preferred Qualifications - Experience designing and operating GlobalProtect VPN solutions, including HIP profiles and zero trust network access (ZTNA) approaches - Strong expertise in Palo Alto advanced features including App-ID, User-ID, Content-ID, SSL decryption, and threat prevention services - Experience operating within multinational, multi-region enterprise environments - Industry certifications such as PCNSE, CCNP Security, CCSE, CISSP, or equivalent - Experience with infrastructure-as-code and network security automation - Background in regulated or high-compliance industries Working Environment -
