This project involves the deployment and configuration of Arista network equipment as part of a migration from a non-standardized legacy environment to a standardized network architecture. The objective is to support the integration of multiple sites into this harmonized LAN environment, ensuring secure, reliable, and continuous network operations throughout the transition.

You’ll take on a hands-on engineering role, contributing directly to configuration, rollout, documentation, and troubleshooting. The environment includes Arista and Cisco infrastructure, Infoblox, and Identity Services Engine (ISE), with strong coordination between distributed engineering teams.
