IREN is a leading AI Cloud Service Provider, delivering large-scale GPU clusters for AI training and inference.  IREN’s vertically integrated platform is underpinned by its expansive portfolio of grid-connected land and data centers in renewable-rich regions across the U.S. and Canada.  

The High Voltage (HV) QA/QC Inspector plays a critical role in delivering safe, reliable power to some of the most advanced, mission-critical data center infrastructure in the industry.

With 100% renewable energy, we build, own and operate our data centers and take pride in being at the forefront of sustainable solutions for the ever-evolving applications of high-performance compute. We believe that human progress is invaluable, but it should be done in the right way – responsibly, sustainably and having a positive impact on the communities we operate in.
