Job description

Job Type: Full-time | Location: Sydney | | 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.

We are seeking an IOC Reliability & Observability Analyst II to support our 24/7 HPC Data Center Operations by performing advanced incident triage, improving alert quality and routing, and maintaining high-quality operational telemetry and reporting. This role partners with engineering and operations teams to identify detection gaps, tune monitoring and dashboards, and implement small automations and enrichment to reduce operational toil and improve time-to-action.

This is not a reporting-only role. You will partner closely with IOC, engineering, and operations teams to validate operational signals, tune alerts and dashboards, leverage AIOps outputs during incident response, and ensure telemetry is actionable for real-time triage and escalation.

Job Requirements

• 3–5 years of experience in IOC/NOC/SRE‑adjacent operations, reliability engineering, observability, or production support roles within 24/7 production environments
• Bachelor’s degree in Computer Science, Data Science, IT, or equivalent hands‑on professional experience
• Demonstrated ability to apply reliability engineering principles (e.g., incident lifecycle, MTTD/MTTR, operational risk) to improve detection, response effectiveness, and overall service stability
• Strong working knowledge of Linux systems, basic networking, and infrastructure dependencies across compute, network, and facility domains
• Practical experience supporting GPU‑based compute environments or high‑density clusters, including analysis of GPU health, performance degradation, and failure patterns to reduce customer impact and improve reliability
• Proven experience owning and improving alert quality, including reduction of false positives, missed detections, poor routing, and alert fatigue across complex environments
• Hands‑on experience maintaining service health dashboards and operational reliability metrics, including supporting SLI/SLO reporting where defined by engineering or service owners
• Ability to correlate logs, metrics, and alerts across distributed systems (including GPU, network, and facility telemetry) to accelerate triage and diagnose complex incidents
• Experience working with AIOps‑enabled outputs (e.g., anomaly detection, event correlation, automated enrichment), validating accuracy during incident triage and escalating when automated signals do not align with operational conditions
• Ability to write or modify small automation artifacts (e.g., scripts, templates, configuration‑driven workflows) to standardize triage, enrich alerts or tickets, and reduce manual operational toil
• Experience ensuring operational data integrity across ticketing systems, incident records, and dashboards to support trend analysis, high‑quality RCAs, and executive reporting
• Strong communication skills with the ability to work cross‑functionally with IOC leadership, engineering, and operations teams, including mentoring less‑experienced analysts
• Strong working experience with IOC/NOC tooling, including ITSM/ticketing systems (e.g., ServiceNow, Jira) and monitoring platforms (e.g., Splunk, Datadog)
• Experience producing operational reports, incident summaries, and shift handoff documentation for IOC leadership and stakeholders
• Familiarity with RCA workflows, including ensuring incident records, timelines, and artifacts are complete and accurate

Other important requirements

• Pre-employment screening, including background check and substance testing may be required according to company policies

Job Responsibilities

• Perform advanced Level 2 incident analysis by reviewing incident data, system behavior, and operational signals across GPU clusters, networks, and facilities to identify recurring issues, improve triage accuracy, and support faster and more effective escalation
• Maintain IOC service health dashboards and operational metrics that reflect alert effectiveness, incident response performance (e.g., MTTD/MTTR), and customer impact for use in day‑to‑day operations and leadership reporting
• Identify alerting and monitoring gaps, under‑monitored systems, and noisy or ineffective alerts; perform day‑to‑day tuning of thresholds, routing, suppression, and enrichment within IOC tooling, and partner with engineering teams when instrumentation changes are required
• Own operational alert quality outcomes by ensuring sustained reductions in false positives, missed detections, poor routing, and alert fatigue through IOC‑approved standards, validation, and continuous review of alert performance
• Analyze GPU health and performance signals (errors, degradation, failure indicators) during incidents to support faster triage, improve escalation quality, and reduce customer impact in GPU‑based environments
• Validate and oversee automated detection and correlation outputs, ensuring alerts, anomalies, and insights are accurate, actionable, and aligned with operational reality
• Implement and maintain IOC‑level automation (e.g., alert routing rules, enrichment fields, ticket templates, runbook scripts) to standardize response and reduce manual toil during incidents
• Ensure ITSM incident and ticket records meet IOC quality standards by validating timelines, categorizations, ownership, and resolution notes; support RCA workflows by providing complete operational inputs and tracking monitoring follow‑ups
• Provide peer coaching and onboarding support to Analyst I team members on triage patterns, alert interpretation, dashboard usage, and IOC runbooks; contribute to and maintain operational documentation
• Support IOC shift operations through detailed incident handoffs, queue hygiene, and coordination with on‑call engineering and facilities teams during escalations
