Senior Scientist, Medicinal Chemistry, Oncology Targeted Discovery

As a Senior Scientist, you will actively contribute to programs in the Oncology Targeted Discovery (OTD) chemistry group. This role is part of our strategy to deliver highly specific state-of-the-art therapeutics including, but not limited to, small molecules, peptides and antibody drug conjugates to treat cancer. The successful candidate will deploy expert-level synthetic organic chemistry skills in designing and building complex molecules, both small and non-small, in the laboratory to drive innovation. Working together with various disciplines, you will have the opportunity to acquire world-class medicinal chemistry skills and contribute to a thriving portfolio of future cancer medicines covering a wide range of modalities. There will also be a chance to support development and adoption of machine-learning/AI tools and emerging technologies.
