Senior Network Engineer

Onsite – Manhattan, NY

CDW Contract – through the end of the year

CDW is seeking a hands‑on Network Engineer to support office buildouts, device configuration, and day‑to‑day network operations across enterprise environments. This role is heavily focused on initial device deployment, configuration, and integration
, working alongside vendors and remote hands teams to bring new sites online.

This is not a pure support role—we’re looking for someone who can own device configuration and onboarding end‑to‑end
.

• Lead network setup for new office builds, including initial device configuration and deployment
• Configure and onboard routers, switches, firewalls, and wireless infrastructure
• Work with vendors and remote hands teams to execute physical installations and ensure proper setup
• Add and manage firewalls within centralized management platforms (e.g., Panorama)
• Configure and integrate Cisco switches, including onboarding into network access control systems (ISE)
• Support and manage SD‑WAN environments (e.g., Meraki or similar platforms)
• Monitor, troubleshoot, and resolve network performance and connectivity issues
• Assist with network upgrades, migrations, and infrastructure projects
• Maintain accurate network documentation and configuration standards

• 4–7+ years of network engineering experience in enterprise environments
• Strong hands‑on experience configuring network devices (routers, switches, firewalls) from the ground up
• Proven experience deploying initial configurations for new network environments
• Deep understanding of TCP/IP, routing protocols (BGP, OSPF, EIGRP), and Layer 2 technologies (VLANs, STP, LACP, HSRP)
• Experience with Cisco routing and switching platforms
• Hands‑on experience with firewall configuration and centralized management (e.g., Panorama)
• Experience integrating Cisco switches into ISE or similar NAC solutions
• Experience working with or managing SD‑WAN technologies (Meraki or similar)
• Strong troubleshooting skills using tools such as packet captures
• Ability to work independently while coordinating with vendors and cross‑functional teams
• Experience with Cisco ACI or other SDN technologies
• Wireless experience (Cisco WLC, Meraki)
• Basic network automation (Python, APIs)
• Firewall platforms such as Palo Alto

This role is ideal for a network engineer who enjoys building environments from the ground up
, working hands‑on with configurations, and playing a key role in bringing new locations online. You’ll have ownership over deployments while collaborating with experienced teams in a fast‑paced, project‑driven environment.
