Cheminformatics Data Scientist
As the world's leading pharmaceutical company, Pfizer holds a unique position with some of the largest and most complex chemical and biological data sets globally. The computational absorption, distribution, metabolism, and excretion (cADME) group at Pfizer is responsible for maximizing the value of ADME, Safety, and Pharmacology data generated to support drug discovery project teams. As a Cheminformatics Data Scientist, you will leverage data-driven approaches to tackle drug discovery chemical and biological challenges. You will apply and develop machine learning models for molecular property prediction, analyze and optimize hit-to-lead and lead optimization strategies from our proprietary knowledge base, and collaborate closely with both internal and external partners to maximize the value of our industry-leading datasets.
Responsibilities:

• Develop and apply cheminformatics data-mining algorithms for the analysis of molecular modeling, virtual screening, and structure-activity relationship (SAR) analysis.
• Process and analyze chemical and biological datasets to evaluate properties such as drug-likeness, ADMET properties, dosing, etc.
• Utilize molecular fingerprints, descriptors, and similarity metrics for compound clustering, classification, and regression.
• Assist in development, maintenance, and monitoring of AI/ML models used for property prediction.
• Optimize data pipelines for processing and storing chemical structures using cheminformatics toolkits (RDKit, OpenEye, etc.).
• Collaborate with cross-functional teams to integrate computational approaches into curation and analysis workflows.
• Maintain best practices in data integrity, reproducibility, and documentation of QSAR AI/ML models.

Required Qualifications:

• Ph.D. with 0 years of experience or Master's degree with 2+ years of experience in Cheminformatics, Computational Chemistry, Bioinformatics, Data Science, or a related field.

• Experience working in a structured collaborative data and software development environment (git).
• Experience using SAR model-building software such as SciKit-Learn, Torch, etc.
• Strong understanding of basic statistical concepts and how to evaluate and track model performance.

Preferred Qualifications:

• Experience using DAGs to define data pipelines, e.g. Luigi, Airflow, Dagster, Prefect, Kubeflow.
• Experience working with relational (SQL) and NoSQL databases for chemical data management.
• Experience working with MLOps tools such as MLFlow, Neptune, or SageMaker.

Sunshine Act
Pfizer reports payments and other transfers of value to health care providers as required by federal and state transparency laws and implementing regulations. These laws and regulations require Pfizer to provide government agencies with information such as a health care provider's name, address and the type of payments or other value received, generally for public disclosure. Subject to further legal review and statutory or regulatory clarification, which Pfizer intends to pursue, reimbursement of recruiting expenses for licensed physicians may constitute a reportable transfer of value under the federal transparency law commonly known as the Sunshine Act. Therefore, if you are a licensed physician who incurs recruiting expenses as a result of interviewing with Pfizer that we pay or reimburse, your name, address and the amount of payments made currently will be reported to the government. If you have questions regarding this matter, please do not hesitate to contact your Talent Acquisition representative.
