About Fluidstack

Fluidstack is the AI Cloud Platform. We build GPU supercomputers for top AI labs, governments, and enterprises. Our customers include Mistral, Poolside, Black Forest Labs, Meta, and more.

Our team is small, highly motivated, and focused on providing a world class supercomputing experience. We put our customers first in everything we do, working hard to not just win the sale, but to win repeated business and customer referrals. We are already operating at hyperscale growth, surpassing nine-figures in ARR. Our recent announcements include building Europe’s largest AI supercomputer for Mistral and a partnership with the French Ministry of Economy to build one of the world’s largest supercomputers of 1GW in France. 

We hold ourselves and each other to high standards. We expect you to care deeply about the work you do, the products you build, and the experience our customers have in every interaction with us.

You must work hard, take ownership from inception to delivery, and approach every problem with an open mind and a positive attitude. We value effectiveness, competence, and a growth mindset.

About the Role

You will work side-by-side with the Founder every day, learning what it takes to build and scale a hypergrowth company. This is a unique opportunity to sit at the centre of a high-growth startup, learn how decisions are made, and help bring discipline and momentum to the company’s most important initiatives.
