You will join a team committed to building and analysing disease knowledge graphs for oncology, respiratory and metabolic disorders.  You will design and apply innovative techniques to wrangle, integrate and analyse scientific data to infer and quantify assertions between drugs, targets and disease processes.  You will help design and develop innovative analytical techniques and interrogate knowledge graphs, retrieving biological insight impactful to drug discovery and development.  You will also contribute to development of computational models directing research and clinical practices.

Projects and algorithm development will be directed towards enhancing and integrating literature derived knowledge, public data sources, and proprietary clinical and pre-clinical multi-layered data (including genomics, imaging, CRISPR, EHR) to:

  • Discover novel drug targets.
  • Identify patterns defining distinct patient groups and biomarkers.
  • Understand drug mechanism of action and safety.
  • Build predictive models directing drug programs.


We are looking for knowledge engineers to help up create intelligent applications powered by knowledge graphs and machine learning. In this deeply technical and close-knit team of data scientists, machine learning engineers and knowledge engineers you will create tools that will advance the standard of healthcare improving the lives of millions of patients across the globe. You will create vocabularies and ontologies to capture vast quantities of biological, medical, chemical, and pharmacological knowledge. You will devise data processing and integration pipelines to expand our knowledge graph with data coming from highly heterogeneous distributed data sources. And you will work with our machine learning engineers and data scientists to populate and exploit the knowledge graph to derive new insights in support for our drug development research.

Our team empowers our scientists from early development to the late stages in drug development, driving innovation and acting as a catalyst for the adoption of the latest advances in Artificial Intelligence and Data Science. We jointly devise novel approaches to drug development and liaise with our platforms team to transition the latest and greatest technologies and algorithms to production.
