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.

• 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.
• 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.
• 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 — Infini Band/Ethernet fabrics, scale‑out storage (e.g., Weka, VAST), and high‑throughput interconnects — sufficient to triage issues and engage the right escalation path.

• 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.

• Actual compensation will be determined based on factors such as experience, qualifications, and market data for the region.
• Total Compensation package may be inclusive of an annual incentive bonus, equity (long‑term incentive).

• 100% company‑paid health insurance premiums (medical, dental, and vision) for employees, 75% company‑paid coverage for dependents.
• Company‑paid short‑term and long‑term disability insurance.
• Voluntary life, critical illness, and accident coverage available.
• Health Savings Accounts (HSA) – when combined…
