Chai Discovery
San Francisco, CA
Job Description
Role Overview

We are hiring research scientists to improve the real-world performance of our foundation models. The work involves planning targeted data generation campaigns, designing evals that accurately measure model performance, and formulating post-training recipes aimed at making models useful for real drug discovery problems.

What You Will Do

You will work in tight loops with our pre-training researchers, research engineers and science team. Your work will ship fast and you'll see your results reach real therapeutic programs across industry.

Why It Might Be a Fit

We look for technical depth paired with interest in the underlying biology. Biological background is not required. All of the following are positive signals: Published research in machine learning for protein, antibody, or small-molecule modelling.
