Responsibilities
We are looking for an experienced Data Center Operations Engineer to join a highly technical group responsible for the commissioning and daily operations of our rapidly-scaling infrastructure within our global data centers.
This role focuses on the "last mile" of data center builds—ensuring new infrastructure is properly commissioned and transitioned to operations—as well as maintaining 100% uptime across our critical facilities portfolio.
Our team is collaborative in nature, spanning many internal departments and external vendors, contractors, consultants, and operations teams.
Your specific work will cover all aspects of our complex distributed data center environments.
This role offers the opportunity to work with cutting-edge liquid cooling technologies in a mission-critical, high-performance computing environment.
You will play a vital role in bridging the gap between construction and operations while maintaining the reliability and efficiency of essential digital infrastructure.
