- Implement predictive analytics and statistical modeling to uncover patterns, trends, and insights from healthcare data
- Evaluate emerging AI technologies, frameworks, and techniques and recommend their appropriate application to government healthcare use cases
- Perform data mining and exploratory data analysis (EDA) using state-of-the-art techniques across structured and unstructured datasets
- Contribute to technical leadership across multiple AI initiatives while remaining an active hands-on developer and model builder
- Build data visualizations, dashboards, and analytical tools to communicate findings clearly to technical and non-technical stakeholders
- Evaluate model performance using appropriate metrics (e.g., accuracy, AUC, precision/recall) and present results in a clear, actionable manner
- Collaborate in an Agile environment with cross-functional teams including engineers, analysts, and stakeholders
- Recommend data-driven solutions and AI strategies aligned with CMS business needs and healthcare policy objectives
Skills
- U.S. citizen or otherwise authorized to work in the United States and able to demonstrate physical residency in the U.S. for at least three (3) of the past five (5) years. Must be able to obtain a U.S. Federal government client badge and pass a Public Trust clearance
