Unlock the Future of Drug Discovery.

Join 4Dcell and become part of a pioneering French biotech on a mission to transform drug discovery and toxicology. We’re engineers and biologists united by a single goal: to replace animal testing with intelligent, in vitro “organ-in-a-well” models that deliver unprecedented predictive power to drive tomorrow’s therapies.

4Dcell has developed two flagship solutions: the SmartHeart™ Platform, which recreates human ventricular tissue in a standard 96-well plate, and the first-in-class SmartSphero™ Technology, enabling the generation of a wide range of organoids.

You’ll collaborate with leading biophysicists, engineers, and biologists to tackle the toughest health challenges, from heart failure and immuno-oncology to pancreas and renal diseases. We combine ambition with a supportive, curiosity-driven culture.
