Reliability Engineer – Electrical & Power Systems (HV to LV) at IREN in Fort Worth, TX

Job description

Job Type: Full Time | Location: Dallas/Fort Worth | Department: Engineering | Reporting to: Senior Manager, Asset Management & Governance | Work Location Type : #hybrid#remote 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. The Reliability Engineer Advisor – Electrical Systems will be the pillar's technical authority for the reliability of IREN's data center electrical infrastructure from utility and high-voltage intake through medium- and low-voltage distribution to the critical load — substations, transformers, switchgear, generators, ATS/STS, UPS, PDU/RPP and busway, protection and controls. The role develops and maintains the enterprise electrical maintenance and testing strategies, ensures every maintenance plan meets IEEE, NFPA, NETA and applicable standards, owns the electrical switching, testing and procedure standards the sites execute, and leads root-cause investigations into electrical failures. It is a hands-on support role to the site teams: reviewing and witnessing switching and testing, supporting incidents, approving fit-for-purpose deviations proposed by campus Asset Managers, and mentoring site engineers and technicians 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. Responsibilities Electrical Maintenance Strategy — develop, maintain and approve the enterprise maintenance and testing strategies for HV, MV and LV electrical assets (task selection, frequencies and test standards) with a documented technical basis; ensure every electrical maintenance plan meets IEEE, NFPA, NETA and other applicable standards and OEM requirements; set the criticality-driven testing regime (acceptance, routine, condition-based) that the campuses execute. Switching, Testing & Procedures — own the electrical switching, isolation and testing standards; develop, review and approve switching orders, MOPs, EOPs and energized-work controls; witness high-consequence switching, transfers, load-bank and integrated systems tests; assure protection-relay settings and coordination studies, arc-flash studies and single-line/one-line currency are maintained and reflected in procedures. Standards Compliance & Assurance — act as the pillar's authority on electrical codes and standards; review site programs for conformance to NFPA 70B/70E, IEEE and NETA; support audits, regulator and customer evidence requests; maintain the electrical testing and inspection records framework. Root-Cause Analysis & Defect Elimination — lead RCA investigations into electrical failures and near-misses using structured methods (5-Whys, Ishikawa, fault tree, event and causal factor analysis, Apollo/TapRooT, Kepner-Tregoe); distinguish symptom, failure mode, mechanism, contributing factors and root cause; define corrective and preventive actions and verify closure; run bad-actor analysis and determine fleet applicability — issuing technical advisories, fleet inspections, strategy or spares changes and OEM engagement where a condition may exist elsewhere. Reliability Engineering — apply RCM, FMEA/FMECA and reliability analytics (MTBF/MTTR, availability, Weibull, P-F intervals) to electrical systems; design condition-monitoring programs (thermography, ultrasound/partial discharge, DGA, battery monitoring, power quality) that produce actionable maintenance decisions; evaluate redundancy, single points of failure and common-mode risks across the electrical topology. Site Team Support — provide day-to-day technical
