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.

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.
