Mechanical Lead

IREN is a vertically integrated AI Cloud provider, delivering large-scale data centers and GPU clusters for AI training and inference. The platform is supported by an expansive portfolio of grid‑connected land and renewable‑rich power across North America, Europe, and APAC.

As a Mechanical Lead you will support the team responsible for operating and maintaining the Central Utility Plant (CUP) and critical cooling infrastructure serving both liquid‑cooled and air‑cooled data halls. You will monitor plant and building automation systems, complete operating rounds, respond to alarms, and coordinate with senior engineers and vendors to protect uptime, safety, and efficiency.

With 100% renewable energy, we build, own and operate data centers, prioritizing sustainable solutions that positively impact the communities we serve.
