Field Systems Admin - Desktop Support

Orange County

Full-Time/Remote/On-Site

PLEASE DO NOT APPLY if you do not live within travel distance of the named geographic area.

We are looking for a motivated and hands-on Field Systems Administrator to join our team. This role is a great fit for someone with a managed service provider (MSP) background who thrives in a fast-paced, client-facing environment. You will be working directly at client sites as needed, resolving end-user issues, maintaining systems and network infrastructure, and serving as the face of IT support for our customers.

This is not a purely remote or help-desk position - you must be comfortable driving to client locations, working independently, and handling a wide variety of technical situations with professionalism and confidence. Company vehicle will be provided.
