The Position

Join the small‑molecule team within AI for Drug Discovery (AI4DD), formerly Prescient Design, at Roche and Genentech’s Computational Sciences Center of Excellence as a Machine Learning Scientist / Senior Machine Learning Scientist in Small Molecule Drug Design. You will develop and apply ML methods and models to accelerate small‑molecule drug design with a focus on structure‑driven approaches, working hand in hand with world‑class computational and medicinal chemists and structural biologists.

The Opportunity

• Design, build, and apply cutting‑edge ML models for small‑molecule drug design, focused on protein–ligand interactions, binding affinity and key molecular properties.
• Train and fine‑tune foundation models for structure prediction, using internally developed and open‑source models on internal datasets.
• Validate and refine ML‑generated hypotheses alongside world‑class computational and medicinal chemists and structural biologists.
• Drive scientific impact through publications, open‑source releases, and conference talks.
• Collaborate widely with computational and experimental researchers at Roche and with academic partners.

Who you are

• You bring deep machine‑learning expertise with a strong foundation in linear algebra, probability and optimization, and hands‑on experience designing & implementing machine learning approaches such as graph neural networks, sequence models, and reinforcement learning.
• You have structure‑driven modelling experience with co‑folding methods, binding‑affinity prediction, and structural‑biology datasets.
• You are fluent in Python and cheminformatics with toolkits such as RDKit and OpenEye, and modern ML frameworks like PyTorch or JAX.
• You hold a PhD or equivalent research depth in machine learning, computational chemistry, chemical engineering or a related quantitative field such as physics or statistics.
• You have a record of scientific excellence evidenced by journal and conference publications or a public portfolio of relevant projects (e.g. hosted on GitHub/GitLab).

Preferred

• Hands‑on experience building structure‑prediction foundation models.
• Experience collaborating directly with medicinal chemists and structural biologists.

If using AI to design the medicines patients need next inspires you, apply now and help accelerate small‑molecule discovery at Roche.
