This is a senior-level IT support role handling escalated complex technical issues across remote and onsite client environments. The Client Engineer will troubleshoot and resolve infrastructure-layer problems spanning M365 administration (Exchange, SharePoint, Teams, Entra ID), macOS support, networking (DNS, DHCP, VPN, firewalls), and generative AI platforms, while traveling to client sites in the metro area as needed. The role requires strong technical depth, independent judgment, excellent client-facing communication skills, and the ability to quickly assess scope and determine whether issues require remote or onsite resolution. A valid driver's license and comfort working in ambiguous situations across both remote and field settings are essential.
