Research Scientist

ABOUT CHAI DISCOVERY Chai is a research lab working on generative models for molecular design. We are building AI infrastructure to engineer new medicines with speed and precision. The world’s largest pharmaceutical companies—including Eli Lilly https://endpoints.news/eli-lilly-chai-discovery-sign-ai-software-deal/, Pfizer https://www.forbes.com/sites/amyfeldman/2026/06/04/why-pfizer-and-eli-lilly-are-betting-on-this-13-billion-ai-drug-discovery-startup/, and Novartis https://www.chaidiscovery.com/news/novartis-partnership—have started adopting our platform across their organizations. Our mission is to unlock progress towards better cures and better science, and we see countless interesting problems on the road ahead. We are known for talent density, rigorous research and pace of execution. Our founders have been at the forefront of this field from the beginning. and we are backed by Sequoia, Index, Thrive, General Catalyst, OpenAI, Dimension and others. ABOUT THE ROLE We are hiring research scientists with outlier insight who can drive new avenues for the work we pursue. From pre-training large diffusion models and architecture design, to post-training and inference time scaling, we draw upon the best ideas from within our domain and across the field. Our models have moved beyond protein structure prediction into real-world therapeutic engineering—and we have only just begun. Our team hails from physics, math, theoretical computer science, computational biology and related disciplines. Everyone is capable and self-sufficient, and everyone helps foster a highly collaborative and collegial environment. Our view is that executing on a long-term research program requires bringing together the right people, with access to the best resources, aligned towards common objectives. And nothing is more essential to our mission and our business than the progress of our research. ABOUT YOU We are looking for researchers driven by impact and foundational progress. We index on sustained focus, rigor and results—people who get obsessed with hard problems and don't give up easily. Folks with a nose for tackling the right questions at the right time, alongside an ample dose of grit and curiosity. We value academic training, research track record, and proven industry accomplishments; we are also more than willing to make a bet on rising talent. We look for engineering capability as well as literature fluency. WE OFFER The opportunity to work at the leading edge of AI research, with world-class people, on a mission that matters. We protect & promote a culture of high velocity and ownership. We offer highly competitive compensation.
