About The Position

As a Palo Alto Subject Matter Expert (SME) on the Network Security Services (NSS) team, you will be the focal point for all Palo Alto-related tasks, operations, and projects. You will work with both corporate and customer leadership to research, analyze, and implement enterprise-wide network security solutions that bridge legacy and next-generation architectures. This role requires a unique blend of deep, hands-on expertise with traditional Gen 2/Gen 3 hardware platforms and modern, cloud-native solutions like Prisma Access (SASE) and Cortex XSOAR. You will provide critical technical oversight, ensuring the stability, security, and modernization of our firewall infrastructure.

A minimum of 7+ years of hands-on experience administering, configuring, and troubleshooting Palo Alto Networks NGFWs in large-scale enterprise/global environments.
Must hold an active Palo Alto Networks Certified Network Security Engineer (PCNSE) certification.
Must be DoD 8140.01 and DoD 8570.01-M IAT Level II compliant (e.g., Security+ CE).
Must be able to successfully obtain/maintain a CSSP Infrastructure Support certification within 120 days of the start date.
Deep, practical knowledge of legacy Gen 2/Gen 3 hardware (e.g., PA-3000, PA-5000 series), including legacy CLI, physical hardware troubleshooting, and line-card replacements.
Direct experience deploying and managing modern PAN-OS architectures, including Prisma Access (SASE), Prisma SD-WAN, and virtual firewalls (VM-Series) in public/private cloud environments (AWS, Azure, or GCP).
Proven expertise utilizing Panorama for centralized policy management, template/device group inheritance, and pushing configurations across a hybrid fleet.
Advanced understanding of core networking protocols critical to firewall routing and legacy-to-modern transitions, specifically BGP, OSPF, IPSec VPNs, and NAT.
Bachelor’s degree in a related field (e.g., IT, Cybersecurity, Computer Science). Additional years of relevant experience may be considered in lieu of a degree.
