About Chai Discovery

Chai Discovery builds frontier AI models to design molecules and transform how new cures are found. We are a craft-obsessed team setting out to re-architect drug discovery and save lives.

The Chai founding team brought together leading researchers in this space and top silicon valley operators. Our founders led seminal accomplishments at top AI-for-biology programs and labs, co-invented protein language modelling, built state-of-the-art folding algorithms, and sold AI adopted by top-10 pharma companies. We are backed by top-tier investors, including OpenAI, Thrive Capital, Dimension, Conviction, Lachy Groom, Amplify, and many more.

About the role

As Chai’s first Product Designer, you will wrap cutting-edge AI models into intuitive tools that scientists find indispensable for their work. You’ll own the end-to-end design process, user research, wire-frames, high-fidelity mock-ups, design system, and dashboards that scientist use to query models, visualize molecular structures, and interpret data with our AI in the loop You’ll guide the product to optimize clarity, consistency, and user delight in a domain that is often cluttered and technical.

After years of foundational R&D, Chai's models are moving beyond protein structure prediction into real-world therapeutic engineering. This is a chance to bring the most advanced AI drug design models to market, working alongside a craft-obsessed team of micro pessimists and macro-optimists.
