Network Engineering Manager
Role Overview
Job Type: Full-Time | Location: Remote | Department: Network | Reporting to: Vice President, Cloud | Work Location Type: #remote #hybrid 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.
The Network Engineering Manager (AI HPC) leads our US network engineering team: around 10-20 engineers who design, build and run the high-performance networks behind our AI data centers.
You will be accountable for what the team delivers across our US sites and for how the team grows.
That means hiring well, developing every engineer, and building the standards and habits that let us bring new GPU capacity online quickly and reliably.
This is a hands-on technical leadership role.
You need to hold your own in a fabric design review or a difficult troubleshooting call, but you will be measured mainly by the strength of the team you build and the engineers you develop.
Job requirements
• 10+ years in network engineering, including at least 3 years directly managing engineers (hiring, performance reviews and career development).
• A track record of developing engineers: people you have hired, coached and promoted, and teams that learned to deliver without you in the detail.
• Experience growing a technical team through hiring: defining roles, running structured interviews and technical assessments, and onboarding new starters.
• Deep hands-on background in large-scale data center networks, including Layer 2/3 (VLANs, VXLAN, BGP EVPN, OSPF, IS-IS) and Clos/ECMP fabric design, enough to review designs and coach senior engineers.
• Experience delivering network builds for new data centers or major expansions against fixed dates, working with construction, electrical and operations teams.
• Excellent written and verbal communication, including explaining technical risk and trade-offs to non-network stakeholders and senior leaders.
• Strong ownership mindset and a great attitude.
• Based in the US, able to travel regularly to our data center sites and to work flexible hours during critical builds and incidents.
