Description

Job Type: Full-time | Location: Dallas/Fort Worth, TX | Department: Operations | Reporting to: Technical Operations Manager | Work Location Type: #onsite 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 — InfiniBand/Ethernet fabrics, scale-out storage (e.g., Weka, VAST), and high-throughput interconnects — sufficient to triage issues and engage the right escalation path. This role operates in a 24×7 IOC/NOC environment and works 12‑hour rotating shifts on a 4‑days‑on / 3‑days‑off, alternating with 3‑days‑on / 4‑days‑off schedule. The IOC Systems Specialist will focus on the following as well as other job-related duties and/or projects as assigned. * 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. At IREN, we offer a highly competitive compensation package that includes base salary, annual performance incentives, and opportunities to build long-term wealth through equity programs. These offerings are part of our broader total rewards package, thoughtfully designed to support your health, well-being, and long-term success.
