16h•Onsite

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.

Requirements

2–5 years of experience operating or supporting HPC clusters in a production or IOC/NOC environment, including incident triage, change execution, and coordination with engineering teams.
Working knowledge of Kubernetes (bare-metal a plus) sufficient to triage workloads, interpret cluster state, and execute documented operational procedures.
Operational experience with the Slurm workload manager — job triage, queue and node health checks, and escalation of scheduler issues to engineering.
Familiarity with HPC monitoring and observability tooling for alerting, log triage, runbook execution, and proactive issue detection.
Demonstrated track record of incident response, root cause analysis, and contributing to operational improvements in complex production systems.
Working understanding of cloud platforms (AWS, Azure, or GCP) and how they integrate with on-premises HPC environments.
Working knowledge of the network and storage components common to HPC — InfiniBand/Ethernet fabrics, scale-out storage (e.g., Weka, VAST), and high-throughput interconnects — sufficient to triage issues and engage the right escalation path.

Nice To Haves

Post-secondary education in Computer Science, Engineering, or a related technical field is an asset; equivalent hands-on operational experience is equally valued.
Relevant certifications are advantageous — e.g., CKA/CKAD, Linux+/RHCSA, ITIL Foundation, CompTIA Server+, or HPC/GPU vendor certifications.

Responsibilities

Provide Tier 2 operational support for HPC cloud environments, ensuring high availability, performance stability, and adherence to SLAs.
Monitor, troubleshoot, and resolve complex incidents across HPC infrastructure, including Kubernetes, Slurm, cluster management systems, and associated cloud services.
Act as the escalation point from Tier 1, performing root cause analysis (RCA) and coordinating with Tier 3/engineering teams for defect resolution and permanent fixes.
Operate and maintain monitoring, alerting, and observability tooling to proactively detect issues and minimise service disruption.
Execute operational changes, patches, upgrades, and maintenance activities in line with change management processes.
Maintain and improve operational documentation, including runbooks, playbooks, incident reports, and knowledge base articles to support efficient IOC operations.
Contribute to continuous service improvement by identifying recurring issues, operational risks, and automation opportunities within the HPC environment.
Support tooling integration and operational readiness for new HPC capabilities prior to handover into production support.
Provide technical guidance and mentoring to Tier 1, DC Techs, enhancing IOC capability and knowledge depth.
Participate in on-call rotations and major incident response activities.
