Job description

About Fluidstack

We exist to make humanity more free. For most of human history, you farmed or you starved. Technology gave people more time for the things they wanted to do, instead of things they had to do. Powerful AI will be the biggest lever for human choice we\'ve ever built - but only if models are aligned with what humanity actually wants. There are groups building AI who don\'t share these goals. Whoever deploys frontier compute infrastructure fastest will decide whether AI expands human freedom or shrinks it.

We\'re singularly focused on delivering 10 to 100s of GWs of compute faster than anyone else, rethinking every layer of the stack. We acquire power, design and build data centers, and operate them - with teams spanning hardware and software. Speed and scale are our key differentiators. Come be a part of building civilization-scale infrastructure for AI.

We hire people who care deeply about this problem space. If that is you, please apply!

The Network Team

Examples of key problems the team is working on

• Build the networks the frontier of AI trains on. Fabrics for 100k+ accelerator clusters, backbones between gigawatt campuses, and every network in between.

• Run 10s to 100s of GWs of networks as one machine. Training fabrics for 100k+ accelerators, backbone, corp, and BMS/EPMS, one architecture across gigawatt campuses.

• Deliver a full site network in days, not quarters. Designs generated from source-of-truth models, devices turned up by ZTP, every link validated by machine. At this scale, manual is an outage.

Role Scope

• Own external connectivity: carriers, dark fiber, internet exchanges, and cloud interconnects across the fleet.

• Plan backbone capacity between sites years ahead of the traffic that will fill it.

• Negotiate technical terms with carriers and fiber providers alongside sourcing.

• Own the connectivity roadmap: diversity, latency, and cost engineered deliberately.

What We\'re Looking For

• The below is a starting point. We always make space for exceptional people, so if you don\'t fit this role exactly, tell us where you would.

• You\'ve engineered carrier and long-haul connectivity at scale.

• You\'ve procured dark fiber and lit services and know where the contracts hide risk.

• You plan capacity with data and buy ahead of need.

• You hold carriers to SLAs with escalation paths you built yourself.

• Bonus: Long-haul and subsea systems. DWDM. Peering strategy. Fiber route analysis.

We are committed to pay equity and transparency.
