Network Engineer L2

Network Engineer L2

Location: Hybrid – Newark / Dover, Delaware Area | Occasional Onsite

Employment Type: Full-Time

Level: Mid-Level

Start Date: ASAP

Primary Focus: Microsoft Azure Networking, Terraform & Zscaler

Position Overview

Our client is seeking an experienced Network Engineer L2 to support a significant expansion and modernization of its enterprise network environment, with a primary focus on Microsoft Azure networking.

The organization is actively moving more of its infrastructure into Azure and expanding its cloud footprint across both the East Coast and West Coast. As a result, the #1 requirement for this position is strong, hands-on Azure networking experience.

The ideal candidate will have experience not only supporting Azure network environments, but also building and deploying Azure networking infrastructure using Terraform and reusable templates. This individual should be comfortable implementing infrastructure, troubleshooting complex connectivity issues, and supporting cloud expansion initiatives in a production enterprise environment.

In addition to Azure, the engineer will support Zscaler secure access technologies and may assist with Cisco routing and switching, firewalls, Meraki, WAN connectivity, SCADA networking, and other enterprise network technologies.

This is a hands-on engineering position requiring someone who can independently troubleshoot complex issues, implement infrastructure changes, lead assigned technical initiatives, and coordinate effectively across internal technology teams and external vendors.

• Network Security Groups (NSGs)
• VPN connectivity
• Virtual WAN
• ExpressRoute
• Azure Firewall
• Hands-on experience with Terraform, including creating templates and deploying infrastructure into Azure environments.
• Experience with Infrastructure as Code (IaC) and repeatable/automated infrastructure deployment practices.
• Strong understanding of TCP/IP, routing, switching, VLANs, DNS, DHCP, VPNs, firewalls, NAT, and network troubleshooting.
• Experience supporting Zscaler Internet Access (ZIA), Zscaler Private Access (ZPA), or comparable secure access technologies.
• Experience troubleshooting connectivity across Azure, on-premises, WAN, VPN, and Internet environments.
• Experience implementing network infrastructure changes within enterprise production environments.
