Job description

We are seeking a Network Engineer L2 to support, implement, and enhance enterprise network infrastructure with an initial primary focus on Microsoft Azure networking and Zscaler secure access technologies.

This role combines hands on engineering, advanced troubleshooting, project implementation, operational support, documentation, and cross functional coordination across cloud and enterprise networking environments.

The ideal candidate will have strong enterprise networking fundamentals along with practical experience supporting cloud networking and secure access platforms. While the primary focus will initially be Azure and Zscaler, this position may also support Cisco routing and switching, firewalls, Meraki, WAN connectivity, SCADA networking, and other enterprise networking initiatives as business needs evolve.

This position requires the ability to independently troubleshoot complex network issues, implement infrastructure changes, coordinate with vendors and internal teams, and provide escalation support for critical network services.

• Configure, support, and troubleshoot Azure networking services including Virtual Networks, subnets, route tables, Network Security Groups, VPN connectivity, Virtual WAN, ExpressRoute, Azure Firewall, and related hybrid connectivity technologies
• Support connectivity between on premise infrastructure, Azure environments, corporate locations, remote sites, and external services
• Participate in Azure regional expansion, network resiliency, disaster recovery, and cloud modernization initiatives
• Configure, support, and troubleshoot Zscaler Internet Access and Zscaler Private Access
• Support ZIA web filtering, traffic forwarding, Internet access, security policies, and related configurations
• Support ZPA application access, application segments, server groups, and access policies
• Troubleshoot Zscaler Client Connector, authentication, application access, Internet access, and traffic forwarding issues
• Monitor Azure and Zscaler network health, connectivity, performance, and availability
• Troubleshoot complex routing, VPN, DNS, firewall, cloud connectivity, and application access issues
• Implement network infrastructure changes using established configuration and change management processes
• Participate in network upgrades, migrations, platform expansion, lifecycle management, and vulnerability remediation activities
• Lead assigned technical implementations and coordinate project activities with internal teams, vendors, and service providers
• Coordinate technical activities with Server, Security, Endpoint, Application, Service Desk, and other technology teams
• Participate in incident response, problem management, root cause analysis, and outage resolution
• Maintain network diagrams, IP addressing information, configuration standards, procedures, and technical documentation
• Recommend improvements to network reliability, security, performance, automation, and operational processes
• Provide escalation support to Network Engineer L1 and operational support resources
• Participate in the Network Engineering on call rotation and provide support for critical infrastructure incidents as required
• Assist with Cisco routing, switching, firewalls, Meraki, WAN, SCADA, and other Network Engineering initiatives as needed

Qualifications

• Strong enterprise networking experience
• Strong understanding of TCP/IP, routing, switching, VLANs, DNS, DHCP, VPNs, firewalls, NAT, and network troubleshooting
• Experience supporting Microsoft Azure networking, Zscaler, or comparable cloud and secure access technologies
• Experience with Azure Virtual Networks, route tables, Network Security Groups, VPN connectivity, Virtual WAN, ExpressRoute, Azure Firewall, or similar cloud networking technologies
• Experience supporting Zscaler Internet Access, Zscaler Private Access, or comparable secure access technologies
• Experience troubleshooting connectivity across cloud, on premise, WAN, VPN, and Internet environments
• Experience implementing network infrastructure changes in production environments
• Familiarity with Cisco routing, switching, firewalls, and Meraki technologies
• Ability to independently troubleshoot complex technical issues and drive them through resolution
• Experience working with internal technology teams, vendors, carriers, service providers, and third party support organizations
• Strong verbal and written communication skills
• Strong documentation and organizational skills
• Ability to manage multiple technical activities and projects simultaneously

• Primary assignment will initially focus on Microsoft Azure networking and Zscaler
• Engineers may be reassigned to other network platforms, technologies, projects, or operational responsibilities based on business needs
• Expected to provide technical escalation support and contribute to the development of network standards, documentation, and operational procedures
• Expected to work across the broader enterprise network environment rather than being limited to a single technology platform
