About the Position

AI Engineer

Welcome to Nutrium

Before you apply, here's the key thing: our mission is to promote global well-being by making quality 1:1 nutrition accessible to everyone.

A lot has changed since we started, but our mission is still at the heart of everything we do - it's written in our culture book, in our proposals, in our docs, and it guides every decision we make.

It’s also what allowed us, for years, to improve the experience of nutrition professionals and their patients through the world's #1 nutrition counseling platform. But we didn't stop there.

Today, with Nutrium Care, we're taking the next step: bringing real, personalized nutrition to people anytime, anywhere, and helping them build healthier, happier lives.

Along the way, we raised our Series A and surpassed €15M in funding, partnered with global leaders like Vodafone, Adidas, Wellhub, and Linde, and reached millions of people around the world.

From day one, we also knew something else: building this future would take more than great tech. It would take a place where talented people can grow, feel supported, and actually enjoy the journey along the way.
