What You'll Bring • At least 10 years of enterprise network infrastructure experience, including 3+ years of hands-on Zscaler ZIA/ZPA design and deployment at scale. • Recognized depth in Zero Trust / SASE architecture with expertise in ZTNA, proxy/SWG, SSL inspection, and cloud security. • Hands-on Palo Alto (PAN-OS, GlobalProtect, Panorama) and enterprise VPN experience. • Aruba wireless and Cisco LAN/WAN (routing, switching, 802.1x) fundamentals. • Strong TCP/IP, DNS, DHCP, TLS/DTLS, BGP, and QoS troubleshooting skills. • Multi-cloud (AWS/Azure/GCP) networking and site-to-cloud connectivity experience. • Automation mindset: Python scripting, API config, and log observability (SQL/Snowflake a plus). • Strong ITSM management, documentation, and communication skills. Nice to Have • Certifications: Zscaler (ZCCA-IA/PA, ZDTA), Palo Alto (PCNSE), Aruba (ACMA/ACMP), or Cisco (CCNA/CCNP). • Experience migrating legacy VPNs (GlobalProtect) to ZPA. • Familiarity with SASE and network-as-code/IaC (Terraform). • Experience operating in high-growth SaaS or cloud-native environments.
