• Experience building multi-objective optimization engines to navigate complex trade-offs using evolutionary algorithms, reinforcement learning, or MILP.
• Proficiency with programming languages Python and SQL.
• Experience with python LLM tools (e.g., DSPy, LangChain), optimization tools (e.g., pymoo) and ML tools (e.g., Scikit-learn, XGBoost, Optuna, PyMC).
• Familiarity with clinical operational data, real world data, electronic health records and claims, and financial data.
• A record of scientific communication through publications, conference presentations, open-source contributions, or equivalent research outputs.

Responsabilidades

• Conduct research, build, test, and improve ML, GenAI, optimization pipelines for clinical development and trial operations.
• Analyze, prepare, and leverage operational, RWD, and cost data to build ML models and optimization engines to predict outcomes, tradeoffs, and optimal scenarios.
• Develop and evaluate LLM-enabled workflows for document extraction, protocol comparison, and eligibility Assessment.
• Conduct stochastic simulations to forecast enrollment and patient journey outcomes.
• Design experiments and evaluation metrics to support validation, monitoring, data-quality, and responsible-AI practices.
• Contribute reusable code and data pipelines in collaboration with data scientists, engineers, and clinical-development partners.
• Communicate findings and recommendations to technical and non-technical stakeholders and support dissemination.

J&J Innovative Medicine - Data, Data Science, and AI - Global Development (DDSAI GD) is recruiting a Postdoctoral Scientist - AI/ML and Optimization. The ideal candidate will apply machine learning (ML), generative AI (GenAI), and optimization techniques to develop computational solutions that support and enhance global clinical operations, including enrollment forecasting, cost estimation and optimization, and country and site selection.

Key Responsibilities

• Conduct research, build, test, and improve ML, GenAI, optimization pipelines for clinical development and trial operations.
• Analyze, prepare, and leverage operational, RWD, and cost data to build ML models and optimization engines to 1) predict outcomes of interest, 2) highlight tradeoffs between competing trial objectives, 3) recommend optimal operational scenarios, and 4) generate actionable insights, enabling early intervention and risk management.
• Develop and evaluate LLM-enabled workflows for document extraction, protocol comparison, trial similarity assessment, data harmonization, clinical-concept interpretation, and eligibility-criteria assessment.
• Stochastic simulations to forecast operational and patient journey outcomes including enrollment and patient study completion.
• Design experiments and tailored evaluation metrics and frameworks to support validation, monitoring, data-quality, and responsible-AI practices.
• Contribute reusable code, data pipelines, documentation in collaboration with data scientists, engineers, and clinical-development partners.
• Communicate research findings, analytical methods, and recommendations clearly to technical and non-technical stakeholders and contribute to internal or external scientific dissemination.

Required Qualifications
