## Description

You'll be an engineer other technicians escalate to when something doesn't add up, the one leading infrastructure projects from scoping through cutover, and a familiar face at our key client sites across the region. You'll split your time between our office, client locations, and remote support - with the judgment to know when each is needed.

What You'll Do

 * Own escalations from Tier 1/2 support - diagnose and resolve the network, server, and infrastructure issues that stump the rest of the team

 * Design and lead infrastructure projects for clients: network builds, server migrations, cloud transitions, and security hardening

 * Serve as the primary technical point of contact for a portfolio of client accounts, translating business needs into IT solutions

 * Maintain and improve network environments with diverse hardware ecosystems - routing, switching, firewalls, IoT and wireless - across multiple client sites.

 * Mentor Tier 1/2 engineers and technicians, building the bench strength of the team

 * Keep documentation, network diagrams, and SOPs current for every environment you touch

 * Participate in an on-call rotation for after-hours critical incidents
