Principal Data Scientist

About AQEMIA

AQEMIA is a drug invention company dedicated to creating entirely new medicines to address major unmet medical needs. At the core of our mission is QEMI, our proprietary molecule-invention platform, which uniquely combines cutting-edge science with advanced technology. Powered by physics-based modeling, statistical mechanics, and generative AI, QEMI allows our teams to design novel drug candidates from first principles.

What makes AQEMIA different is our commitment to true innovation: our research is dedicated to the invention of new molecular entities, not the refinement of existing ones. We focus on inventing never-before-seen molecules, without relying on experimental data, and advancing them into a growing pipeline of proprietary programs and strategic partnerships with leading pharmaceutical companies.

Our most advanced preclinical programs are currently in vivo optimization, targeting diseases still waiting for effective treatments, offering our teams the opportunity to work on science that can make a real difference in people’s lives.

About Our Team

AQEMIA brings together a diverse, multidisciplinary team of 65+ professionals based in Paris and London. Our scientists and engineers, including chemists, physicists, machine learning experts, and software engineers, work side by side to push the boundaries of early-stage drug discovery.

This close collaboration across disciplines is central to our approach, enabling us to tackle complex scientific challenges from first principles and translate cutting-edge ideas into novel therapeutic candidates. At AQEMIA, team members are encouraged to contribute their expertise, learn from one another, and play an active role in shaping the future of drug invention.

The Role

You will join the Platform department, AQEMIA’s department responsible for developing and running methods to accelerate the search for molecules. As Principal Data Scientist, your mission is to lead and scale data science initiatives that guide decision-making in virtual screening, hit optimisation and hit-to-lead development. You will contribute across multiple projects within the Platform organisation and collaborate with scientific and technical teams to define and improve AQEMIA’s data-driven approaches.

What You’ll Do

• Design and improve data-driven methods to benchmark and optimise in silico screening techniques
• Develop models (bayesian optimisation for instance) and analyses to configure optimal screening workflows for each target
• Guide compound selection strategies through quantitative, evidence-based approaches
• Mentor and support data scientists within the Platform team, promoting scientific excellence and skill development
• Contribute to cross-functional technical strategy, working closely with engineers and ML scientists to improve tools, workflows, and model reliability across AQEMIA’s platforms
• Drive applied research projects in areas such as uncertainty quantification and propagation within Binding Free Energy pipelines
