Research Scientist

We are hiring research scientists with outlier insight who can open new avenues for the work we pursue. Our models have moved beyond protein structure prediction into real-world therapeutic engineering, and we have only just begun. We draw on the best ideas from within our domain and from across the field: pre-training large diffusion models, architecture design, post-training, and inference-time scaling.

Our team comes from physics, math, theoretical computer science, engineering, and computational biology. What we share is a record of getting hard, open-ended problems to work, and together we foster a culture of rigor, smart risk-taking, and constant collaboration. Many of us had never worked on molecules or biology before Chai.

This is the place to apply if your strongest work happened outside AI for biology, or if you aren't sure which of our research roles fits you best.

We are looking for researchers driven by impact. We index on grit, rigor and results.
