Role Overview
The Network Security Team is seeking a Sr. Network and Firewall Security Engineer to secure and operate connectivity across global offices and data centers. This is a hands-on role requiring deep expertise in Palo Alto firewalls, including design, deployment, migration, and ongoing optimization of security policies in complex enterprise environments. The engineer will partner across infrastructure teams to ensure secure, highly available connectivity, while also supporting internal and external stakeholders with a strong service mindset. Candidates must be self-starters with strong critical thinking skills, capable of operating independently and taking ownership of complex problems from initial detection through resolution.
This role requires advanced troubleshooting capabilities, including hands-on experience with Palo Alto CLI-based debugging typical of Tier 2/Tier 3 TAC scenarios, as well as strong foundational networking knowledge across routing protocols and packet-level analysis. The ideal candidate is a natural communicator who can drive problem resolution in large, cross-functional settings, clearly articulate technical findings, and influence outcomes across engineering, security, and operations teams. Success also requires the ability to communicate effectively with senior leadership—translating deep technical issues, risks, and trade-offs into concise, actionable insights—while mentoring junior engineers and helping elevate the overall capability of the team.
Your responsibilities will be:
Design, deploy, and migrate Palo Alto firewall solutions across global environments, including architecture of security policies, segmentation, SSL decryption, and centralized management
Lead complex security and network integrations by applying strong core networking principles (BGP, OSPF, routing design, failover, traffic engineering) to ensure resilient, high-performance connectivity
Partner with network, cloud, and infrastructure teams to design and implement secure, scalable connectivity across on-prem and hybrid environments
Serve as a senior escalation point, driving advanced troubleshooting across firewalls and underlying network infrastructure, including deep packet, flow, and session-level analysis
Support network security operations and incident response, diagnosing complex connectivity issues involving routing, NAT, policy enforcement, and application behavior
Mentor engineers and NOC staff, reinforcing strong networking fundamentals, structured troubleshooting, and operational best practices
Manage and prioritize work intake while delivering clear, direct communication to both technical stakeholders and senior leadership
Evaluate and recommend enhancements to security architecture, firewall capabilities, and network design to continuously improve reliability and security posture
The ideal candidate has
Minimum Qualifications
7+ years of network and security engineering experience across enterprise routing, switching, and firewall platforms, with strong foundations in secure connectivity and network design
5+ years of hands-on experience managing Palo Alto firewalls, including SSL decryption, security profiles, and Panorama-based centralized management (required)
Strong, demonstrated experience designing and troubleshooting complex network and security environments, including routing protocols (BGP, OSPF), NAT, and packet-level analysis in production environments
Deep understanding of TCP/IP, traffic flows, and structured troubleshooting methodologies across network and security domains
Strong understanding of network security design principles, including segmentation, access control, and secure architecture patterns (zone-based design, microsegmentation, zero-trust concepts)
Experience leading firewall migrations and contributing to enterprise network security architecture
Experience with scripting or API-driven automation to improve operational efficiency
Preferred Qualifications
Experience across additional enterprise networking platforms and edge technologies, including Arista or similar environments, proxy platforms, load balancers (e.g., F5), and multi-vendor infrastructure
Experience with cloud networking and security, including AWS networking constructs and security controls, as well as edge security platforms such as Cloudflare or similar services
Familiarity with modern application and container networking models, including Kubernetes networking, segmentation, and network policies
Experience participating in or leading multi-vendor infrastructure migrations in large-scale environments
Relevant industry certifications such as Palo Alto, Cisco, or equivalent
