The Data Center Technician L3 is an advanced, hands-on role supporting the build-out and ongoing operation of a high-performance, enterprise-scale data center environment supporting advanced compute and large-scale infrastructure deployments.
This position is designed for experienced technicians who are comfortable owning complex tasks and serving as a primary technical escalation point within the site. You will play a key role during the initial deployment phase, contributing to hardware installation, structured cabling, and infrastructure bring-up.
