High Voltage Design Engineer (New South Wales)

Job Type: Full‑Time | Location: Australia | Department: Engineering | Reporting to: VP, Engineering | 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 centres in renewable‑rich regions across the U.S. and Canada. Reporting to the Vice President of Engineering, the High Voltage Design Engineer will act as owner’s representative in the design of our high and medium voltage substation infrastructure for our Australian data centre projects. This role is ideal for an engineer with strong detailed design experience from a consulting/engineering firm environment, who is looking to transition into an owner’s engineering role with end‑to‑end responsibility—from early concept through energisation and operations. You will work across our Australian project portfolio, partnering with utilities, EPCs, and internal stakeholders to deliver standardised, scalable, and highly reliable substation solutions. With 100 % renewable energy, we build, own and operate our data centres 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. Job requirements
