About the Role

We are seeking a Senior Data Scientist to own the development, validation, and operationalization of diagnostic AI models for rare diseases. This role will drive analytical rigor in our testing programs and influence product decisions through data insights.

Responsibilities

  • Own the end-to-end development, validation, and operationalization of PG's predictive diagnostic AI models, from feature engineering through production deployment.
  • Run prospective testing experiments, applying diagnostic models to undiagnosed patients and coordinating testing to improve model performance.
  • Build and maintain PG's synthetic patient data pipeline for research programs and model development.
  • Optimize the patient intake experience using NLP and multimodal data analysis to maximize data quality and conversion.
  • Own API usage and cost optimization across PG's AI stack, including prompt engineering, model evaluation, and performance monitoring.
  • Conduct ad hoc strategic analyses to inform product prioritization, causality assessment, and generate customer-facing program insights.
  • Establish MLOps infrastructure, including model monitoring, drift detection, API observability, and operational processes.
  • Conduct blue sky research initiatives to create value from data.
  • Collaborate with Data Engineering to build a robust, scalable data foundation.

Requirements

  • 7+ years of experience in data science, machine learning engineering, or a closely related field.
  • Strong Python proficiency and fluency across the core data science stack: pandas, NumPy, scikit-learn, PySpark, and SQL.
  • Demonstrated end-to-end ML experience, including problem definition, feature engineering, validation, deployment, and monitoring in a production environment.
  • Experience with NLP techniques and applying language models to real-world problems.
  • Comfort with prompt engineering and evaluating external AI API performance (e.g., OpenAI).
  • A track record of operating with high ownership in lean, fast-moving environments.
  • Strong analytical communication skills, capable of translating complex model outputs into clear, actionable narratives for diverse audiences.
  • Empathy and a patient-focused motivation to have a positive impact on humanity.
  • Comfort in a fast-paced, often ambiguous environment with rapid change.
  • Action-oriented and excited to build a company from the ground up.
