Nice To Haves

Master’s preferred
Relevant certifications: Palo Alto (PCNSE/PCNSA), Cisco (CCNP/CCIE), CISSP, SANS/GIAC.
Experience with SD-WAN, SASE, cloud networking (AWS, Azure), and micro-segmentation technologies.
Prior experience leading large-scale migrations, global rollouts, or managed security

Responsibilities

Define enterprise network security architecture and roadmap for next-generation firewalls, web security proxies, VPNs, and related controls across data centers, cloud, and branch/remote sites.
Lead design and implementation of Palo Alto Networks NGFW solutions at scale, including architecture patterns for segmentation, security policies, NAT, VPNs (IPsec/SSL), threat prevention, URL filtering, TLS/SSL decryption, and high-availability/clustering.
Architect and validate network designs for Cisco routing and switching across LAN/WAN, ensuring performance, resilience, and security for high-throughput environments.
Own architecture and deployment strategies for web security platforms (McAfee Web Gateway / Web Security Proxy) and cloud-based secure web gateways (e.g., Zscaler), including policy models, threat protection, content inspection, and telemetry integration.
Integrate network security solutions with enterprise identity and authentication services (Active Directory, LDAP, RADIUS, TACACS+, 802.1X), enabling centralized policy enforcement and role-based access controls.
Define secure network segmentation, micro-segmentation, and zero-trust network access strategies; produce reference architectures, design patterns, and configuration baselines.
Drive cross-functional security initiatives: large-scale firewall and proxy migrations, datacenter-to-cloud transition, SD-WAN and SASE adoption, and consolidation of security tooling.
Establish governance: security policy lifecycle, rulebase rationalization, change control, risk assessments, and exception processes.
Design and implement logging, telemetry, and monitoring architectures to surface threats, performance issues, and policy violations; integrate with SIEM, SOAR, and observability platforms.
Lead incident response for network security events, conduct root-cause analysis, and define remediation and preventative controls.
Optimize operational processes via automation and IaC (Ansible, Terraform, scripts) for deployment, configuration management, and compliance validation.
Provide technical leadership, mentor engineers, coordinate vendor engagements, and influence executive stakeholders on strategy, budgets, and roadmap.
Ensure architectures meet regulatory, compliance, and audit requirements; produce documentation, diagrams, and security design reviews.
