Senior DevOps Engineer
About The Position
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. 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. As a Senior DevOps Engineer, you will help build and operate the foundational systems that power our GPU-enabled multi-tenant environment. You will design and maintain the infrastructure, automation, and platform abstractions that enable product teams to deliver reliable, scalable, and high-performance services across our cloud and on-prem footprint.
