• TROUBLESHOOTING & DIAGNOSTICS: Performs complex troubleshooting and diagnostics to resolve network issues, ensuring minimal downtime and maintaining network reliability.
• NETWORK MAINTENANCE: Leads routine maintenance and updates on network systems, including applying patches, service packs and security configurations.
• PERFORMANCE MONITORING & OPTIMIZATION: Monitors network performance, maintains system availability and reliability, and makes necessary adjustments to optimize performance.
• SECURITY MEASURES: Sustains network security by leading the implementation of appropriate measures such as firewalls, intrusion detection systems and encryption technologies.
• DISASTER RECOVERY PLANNING: Develops and implements disaster recovery plans to ensure business continuity in case of network failures.
• NETWORK AUTOMATION: Develops and implements automation and tools to streamline network operations, including configuration management, device provisioning and software updates.

Qualifications

• Minimum requirement of 4 years of relevant work experience. Typically reflects 5 years or more of relevant experience.
• Minimum of 5 years of relevant experience in network engineering, network security, or cybersecurity engineering.
• Hands-on experience implementing and supporting SASE or SSE solutions in an enterprise environment.
• Experience deploying and managing SWG and ZTNA technologies.
• Strong understanding of enterprise networking fundamentals, including TCP/IP, routing, switching, DNS, DHCP, VPNs, SSL/TLS, certificates, and network security principles.
• Experience troubleshooting complex connectivity, authentication, and application-access issues across hybrid and cloud environments.

Preferred:

• Experience implementing and administering one or more leading SASE/SSE platforms, such as Netskope, Palo Alto Prisma Access, Zscaler Internet Access (ZIA), or Zscaler Private Access (ZPA).
• Experience designing, implementing, and supporting enterprise firewall platforms, such as Check Point, Palo Alto Networks, or Fortinet, including security policy management, network segmentation, NAT, VPN connectivity, and integration with SASE architectures.
• Deep understanding of SWG capabilities, including URL filtering, SSL/TLS inspection, cloud application visibility and control, malware protection, DLP, threat prevention, and policy enforcement.
• Experience designing ZTNA solutions for secure access to private applications and reducing reliance on traditional VPN technologies.
• Experience with SASE traffic steering and service components, including endpoint clients, GRE/IPsec tunnels, private access connectors or publishers, dedicated egress, and high-availability designs.
• Strong understanding of identity-driven security and integration with Microsoft Entra ID, Okta, Ping Identity, or similar identity providers using SAML, OAuth, OIDC, and SCIM.
• Experience integrating SASE platforms with endpoint security, SIEM, XDR, and security operations workflows.
• Knowledge of cloud networking and security architectures across AWS, Azure, and Google Cloud Platform.
• Experience with policy lifecycle management, security posture assessments, exception governance, and change control for cloud-delivered security services.
• Experience with automation and scripting using Python, PowerShell, REST APIs, Terraform, Ansible, GitHub, or similar tools.
• Experience with network, security, and digital-experience observability tools used to monitor user experience, application performance, and security events.
• Ability to develop technical architecture documentation, low-level design artifacts, implementation plans, operational runbooks, and support models for SASE deployments.
• Experience working within Agile engineering teams using modern engineering and DevSecOps practices.
• Demonstrated ability to provide technical leadership, mentor engineers, and collaborate across network, security, identity, cloud, endpoint, and application teams.
