Role Overview

We are seeking a highly experienced Lead Data Scientist to drive advanced predictive modeling and machine learning initiatives across patient analytics and broader AI-driven business use cases. This role requires a hands-on expert who can independently translate business problems into analytical approaches, build and validate robust machine learning models, engineer features from complex longitudinal datasets, and deliver scalable, production-ready solutions with minimal supervision. The individual will work across the full lifecycle of applied analytics, from exploratory analysis and hypothesis generation to model development, deployment, and ongoing optimization. In addition to solving high-impact patient analytics problems, this role will also contribute to the design and build of internal AI/ML products, accelerators, and intelligent analytics capabilities that support future innovation across the organization.

 

 

ROLES & RESPONSIBILITIES

* Lead end-to-end development of machine learning solutions for patient analytics and related commercial or clinical use cases.
* Independently explore data, frame problems, generate hypotheses, engineer features, train models, validate outcomes, and communicate insights clearly to technical and non-technical stakeholders.
* Build and optimize classification models using methods such as Random Forest, XGBoost, Logistic Regression, and other suitable algorithms based on the business context.
* Design robust modeling pipelines for longitudinal patient-level data, including feature engineering from journeys, events, sequences, and time-based interactions.
* Apply strong model validation techniques including train-test split, cross-validation, out-of-bag validation, and performance evaluation for imbalanced classification problems.
* Develop scalable and reproducible ML workflows, including experiment tracking, model versioning, deployment, and monitoring using MLOps best practices.
* Work with global cross-functional stakeholders to understand business questions, challenge assumptions, propose better analytical approaches, and deliver decision-ready outputs.
* Act as a subject matter expert in solving development and commercial questions using predictive, prescriptive, and applied analytics.
* Perform exploratory and targeted data analyses using statistical techniques, descriptive methods, and hypothesis-driven problem solving.
* Contribute to the design and build of internal AI/ML-based products, accelerators, intelligent dashboards, and automation solutions.
* Partner with engineering and product teams to translate business needs into technical specifications and deploy production-grade analytics assets.
* Work in Linux-based development environments and manage code, environments, and collaboration workflows using Git and related tools.
* Contribute to roadmap discussions for AI tools, reusable data science assets, and future-facing patient analytics capabilities.
* Where relevant, support feature extraction from unstructured text such as medical notes, EMR, or other healthcare text sources using NLP, clinical NLP, NER, or LLM-based approaches.
