Lead enterprise customers in designing, deploying, benchmarking, and optimizing large-scale AI training and inference infrastructure. Create reference architectures for GPU clusters, high-speed networking, distributed storage, and Kubernetes multi-tenancy. Conduct proof-of-concepts and performance testing, optimize distributed workloads, lead technical workshops, resolve production bottlenecks, and translate customer feedback into platform requirements.
IREN is a vertically integrated AI Cloud provider, delivering large-scale data centers and GPU clusters for AI training and inference. IREN’s platform is underpinned by its expansive portfolio of grid-connected land and power in renewable-rich regions across North America, Europe and APAC.
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 Principal Solution Architect, you will sit at the tip of the spear for IREN's AI Cloud platform. You will partner directly with client CTOs, lead ML engineers, and infrastructure architects to design, benchmark, and optimize massively distributed training and inference clusters. You will convert complex customer requirements into optimized hardware/software configurations while creating reference architectures that set industry benchmarks.
