IT Network Specialist

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. 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 looking for an IT Infrastructure Specialist to join our Corporate IT team. Reporting to the Senior Manager, IT, you will own the administration, security and lifecycle of IREN's corporate network and connectivity infrastructure across our global offices — firewalls, switching, wireless, identity-aware network access and remote connectivity.

You'll treat the corporate network as a critical security control surface: enforcing least privilege, maintaining a defensible and well-documented environment, and working closely with our cyber security function on hardening, detection coverage and incident response. The role is focused on IREN's corporate environment (offices, corporate services and end-user connectivity). It is distinct from our Data Center Network Engineering team, which supports customer-facing and HPC/data center networks — though you will collaborate closely with them on interconnectivity and shared services.
