Opportunity to work at the cutting edge of drug development

Hummingbird Bioscience is an innovative clinical-stage biotech company focused on developing precision therapies against hard-to-drug targets to improve treatment outcomes. We harness the latest advances in systems biology and data science to better understand and solve the underlying causes of disease and guide development of our therapeutics.

Enabled by our proprietary Rational Antibody Discovery platform, we discover antibodies against optimal yet elusive epitopes on important targets that have not been successfully drugged, unlocking novel mechanisms of action. We are advancing a rich pipeline of first- and best-in-class precision therapies in oncology and autoimmunity, in collaboration with global partners in academia and industry.

Our highly experienced teams in the US and Singapore span antibody discovery, pharmacology, production and clinical development. Together we aim to accelerate the journey of new drugs from concept to clinical care. For more information, please visit, and follow Hummingbird Bioscience on LinkedIn and Twitter.
