Key Responsibilities

You will:

• Design, develop, benchmark, and implement advanced AI/ML models (self-supervised and supervised) for small molecule drug discovery, including structure prediction co-folding models, affinity prediction models, and de novo design algorithms.
• Collaborate closely with expert medicinal and computational chemists, across AZ sites, to discover optimized hits as starting points for new drug discovery projects.
• Integrate machine learning with domain knowledge in chemistry, biophysics, structural biology, and drug discovery. Ensure generation of high-quality, validated predictions and incorporate new experimental and computational data into models.
• Collaborate cross-functionally in developing Chemistry AI solutions to address critical questions related to small molecule drug discovery, including predictive and agentic solutions.
• Effectively communicate complex technical concepts and results to multidisciplinary project teams and stakeholders.
• Keep abreast of the latest developments in AI for Science, computational chemistry, and structure prediction; proactively identify and evaluate innovative technologies and methodologies relevant to drug discovery.
• Identifying and building strategic partnership opportunities in China (academic or industry) to accelerate impact in AI-driven drug discovery
• Contribute to high-impact scientific publications and patent filings.

Required Qualifications

• Depending on the career level, a PhD or Master's degree in Computer Science, Computational Chemistry, Structural Biology, or a related AI for Science discipline.
• Hands-on experience in developing and applying machine learning/deep learning models for small molecules or biologics, in both self-supervised and supervised ways.
• Experience and expertise in training, retraining, and fine-tuning AI models with new data and towards differentiated scientific applications.
• Demonstrated programming proficiency in Python (and relevant ML/AI frameworks such as TensorFlow, PyTorch, JAX).
• Experience in handling, curating, and analyzing large-scale scientific datasets.
• Ability to work collaboratively in a fast-paced, multidisciplinary, and cross-geographical research environment.
• Clear and effective communication skills, with fluency in English.

Preferred Qualifications

• Knowledge of state-of-the-art approaches in protein structure prediction, including co-folding with different modalities, e.g. proteins, ligands, oligonucleotides.
• Experience with multi-modal machine learning or integrating heterogeneous data types (such as molecules, protein structure data, experimental data).
• Familiarity with large-scale cloud computing and modern data engineering practices.
• Publication record in top-tier AI, computational chemistry, or cheminformatics. journals/conferences.
• Understanding of small molecule drug discovery and computational chemistry approaches.
