Associate Principal Scientist, AI for Chemical Toxicology Full-time

Predictive Safety Modelling Lead

Predictive AI and Data team is responsible for providing AI and Bioinformatics solutions to the scientists across the spectrum of drug development and discovery in AstraZeneca (both pre-clinical and clinical stages). The primary aim is to find ways to accelerate the drug development process by leveraging existing company data in combination with the most cutting-edge AI approaches in day-to-day scientific work across the company.

Introduction to Role

In this role you will lead the next-generation predictive safety modelling at scale, applying chemoinformatics, bioinformatics and AI/ML to deliver decision-shaping safety insights and cross-functional scientific leadership. Provide scientific leadership for predictive safety modelling, integrating chemical and biological data (e.g., Safety Omics, Cell Painting, NAMs) to inform risk assessment and progression decisions. This is a fully hands-on, computational role with cross-functional influence.

Accountabilities

• Develop, optimise and deploy predictive safety models using chemoinformatics, bioinformatics and ML/DL.
• Create reproducible workflows, data QC procedures and model validation frameworks.
• Integrate multimodal data: chemical descriptors, omics, imaging and NAM datasets.
• Serve as scientific lead for project teams and influence program strategy.
• Drive innovation and identify strategic modelling opportunities across R&D.
• Lead collaborations with academia, consortia and technology partners.
• Mentor junior scientists and contribute to capability building.
• Communicate complex modelling concepts to diverse scientific and governance audiences.

Essential Skills/Experience

• PhD in Chemoinformatics, Bioinformatics, Computational Toxicology or related field.
• Strong AI/ML experience (PyTorch, TensorFlow, scikit-learn).
• Advanced Python or R programming skills.
• Familiarity with GitHub, CI/CD pipeline, and best DevOps and MLOps practices.
• Experience with multimodal biological + chemical datasets.
• Proven leadership in delivering impactful modelling work.
• Excellent communication and stakeholder engagement skills.
• Acts as discipline leader and shapes scientific strategy.
• Solves complex problems using scientific judgement.
• Builds strong cross-functional relationships and networks.
• Coaches and mentors others, enhancing team capability.

Desirable Skills/Experience

• Experience with Safety Omics, Cell Painting or imaging data.
• Background in toxicology, pharmacology or ADME.
• Experience with cloud computing or workflow automation.
• Track record of publications in top AI conferences or journals in pharmaceutical research (e.g., NeurIPS, ICML, Nature Machine Intelligence, Nature Communications, NEJM AI, etc.)
• Experience supervising scientists or managing collaborations.
