Antibody Engineer

Chai Discovery is re-architecting drug discovery by building frontier AI foundation models to design molecules.

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

We’re looking to add a few members to our team of scientists and engineers, who obsess over creating the most powerful AI models for antibody discovery, and turning them into products that can transform how medicines are made.

We’re hiring an Antibody Engineer to play a critical role in developing traditional and next-generation biologics at Chai. You’ll take in-silico candidates spanning monoclonals, bispecifics, TCEs, engineered cytokines, multifunctionals, and ADC/DAC formats, then design constructs, run expression and purification campaigns, and develop fit-for-purpose assays that read out affinity, specificity, and developability. The data you generate will feed directly back into our model-training loop, making your experiments the ground truth that guides every next iteration.
