Position Summary

The R&D Data Science organization is seeking a Data Scientist to leverage advanced machine learning, robust data engineering techniques, and domain expertise to drive impactful decisions and generate actionable insights within the Pharmaceutical Sciences & Translational Safety (PSTS) organization. In this role, you will work closely with multidisciplinary teams-including toxicologists, PK/PD specialists, in vivo researchers, and safety professionals-to create AI-ready datasets, develop predictive models, and deliver analytical solutions that promote improved safety evaluations and facilitate translational research.

The successful candidate possesses hands-on experience in machine learning and data engineering, complemented by a solid understanding of toxicology, pharmacokinetics/pharmacodynamics (PK/PD), in vivo experimentation, and translational science. Additionally, this role requires strong communication and problem-solving skills, a passion for innovation, and the ability to adapt to evolving scientific challenges in pharmaceutical R&D.

Key Responsibilities

Machine Learning & Modeling

  • Develop and deploy ML/AI models to support safety signal detection, dose selection, PK/PD modeling, toxicology insights, and translational interpretation.
  • Implement representationlearning, predictive modeling, and multivariate analytics for datasets spanning in vivo studies, in vitro assays, exposureresponse data, and pathology information.
  • Partner with scientific SMEs to design modeling strategies aligned with PSTS decision points.
  • Apply model governance, versioning, and validation standards consistent with R&D AI practices.

Data Engineering & Pipeline Development

  • Build and maintain scalable data pipelines that integrate PSTSrelevant data sources (e.g., toxicology studies, PK/PD datasets, biomarker readouts, animal study repositories).
  • Transform raw experimental outputs into standardized, analysisready, AIready datasets using Python, R, and cloudnative services.
  • Contribute to harmonized scientific data models in collaboration with data engineering and ontology teams.

Scientific Domain Integration

  • Work directly with toxicology, DMPK, and safety stakeholders to interpret scientific context and translate study designs into computational requirements.
  • Apply understanding of mechanismbased toxicology, exposureresponse concepts, and in vivo study structures to guide data transformations and modeling strategies.
  • Enhance crossstudy comparability via standardized terminologies, metadata practices, and quality checks.
  • Collaborate with PSTS functional experts, R&D Data Science teams, and platform architects to ensure high-quality, scalable data solutions.
