Software Engineer, Developer & Research Platform

Chai builds the design suite for molecules. We train frontier models that learn the underlying foundations of biochemical structure and interaction, so scientists can move faster and pursue targets that other methods cannot reach.

AI is reinventing life sciences the same way it reinvented software engineering, and Chai is at the forefront of this shift. Leading pharmaceutical companies like Eli Lilly, Pfizer, and Novartis are adopting our platform to power their drug discovery programs.

We value diverse perspectives and are ready to find greatness in unexpected places.

Build the tools that accelerate engineering and research at Chai. We believe that the software factory is just as important as the software itself, and you will build the factory that helps the team pursue more ideas in parallel and spend more time on the problems that need their judgment.

Make coding agents more useful across development, testing, and code review.

Work directly with the team to build better development environments, faster tests, and reliable deploys.

Build the research platform where people and agents launch experiments, compare results, and decide what to try next.

We look for strong systems engineering, developer taste, and a record of making other technical people more effective. You notice where tools get in the way, understand the underlying problem, and build something better.

The opportunity to work at the vanguard of AI research and frontier biology, with world-class people, on a mission that matters. We protect & promote a culture of high velocity and ownership. We compensate our team accordingly.
