Reliability Engineer – Electrical & Power Systems (HV to LV)

IREN•Fort Worth, TX

18d•Hybrid

About The Position

The Reliability Engineer – Electrical Systems serves as the 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 critical loads. Covered assets include substations, transformers, switchgear, generators, ATS/STS, UPS, PDU/RPP and busway, protection, and controls. The role develops and maintains enterprise electrical maintenance and testing strategies, ensures maintenance plans comply with applicable IEEE, NFPA, NETA, and other standards, owns electrical switching, testing, and procedure standards, and leads investigations into electrical failures. It also provides hands-on support to site teams by reviewing and witnessing switching and testing, supporting incidents, reviewing proposed deviations, and mentoring site engineers and technicians. IREN is a vertically integrated AI Cloud provider operating data centers and GPU clusters for AI training and inference, supported by grid-connected land and power in renewable-rich regions. The company states that it uses 100% renewable energy and aims to operate responsibly and sustainably while positively impacting its communities. The role develops electrical maintenance strategies and testing regimes; governs switching, isolation, testing, and work controls; assures standards compliance; leads root-cause analysis and defect elimination; applies reliability engineering and analytics; supports campus teams and incident response; reviews changes and lifecycle decisions; and contributes to capability development, governance, and reliability reporting. Regular travel to the Childress campus and other IREN sites is required, as is availability to support electrical incidents outside normal hours when needed. The position is hybrid/remote as specified in the posting, with a Dallas/Fort Worth location. Candidates must be able to commute to the work site daily or plan to relocate before starting. Pre-employment background screening and substance testing may be required. The employee must provide steel-toed boots; other PPE will be supplied.

Experience with electrical acceptance and maintenance testing to ANSI/NETA ATS and MTS, including insulation resistance, power factor/tan delta, transformer DGA and TTR, breaker primary/secondary injection and trip testing, protection-relay coordination, VLF cable testing, battery impedance and capacity testing, infrared thermography, and ultrasound.
Proven root-cause analysis capability using structured methods, with the ability to distinguish failure symptoms, modes, mechanisms, and root causes.
Working command of applicable standards, including NFPA 70, 70B, 70E, 110, and 111; IEEE 3007.2, 493, 1584, C37 and C57 series, and 450/1188/1106; ANSI/NETA ATS, MTS, and ETT; Uptime Institute Tier and TIA-942 practices; and ISO 55001.
Familiarity with reliability analytics such as MTBF/MTTR, Weibull, Pareto and bad-actor analysis, P-F intervals, and condition-based strategy design.
Familiarity with CMMS data such as Fiix, Maximo, or SAP PM, and with EPMS/power-quality systems.
Clear, measured communication skills and ability to work with technicians, site engineers, OEMs, NETA firms, and executives.
Willingness to travel to campuses and support incidents outside normal hours when required.
Must be able to reliably commute to the work site daily or have plans to relocate before starting.
Must provide own steel-toed work boots; other PPE will be supplied.
