Sr Data Scientist

Job Title: Data Scientist Sr

As a Senior Data Scientist supporting the VA's AI Citizen Developer Ecosystem (TOPR 0049), you will lead technical support activities that empower Veterans Health Administration (VHA) staff to leverage artificial intelligence and machine learning solutions across clinical and operational domains. Working within a cutting-edge federal healthcare environment, you will apply advanced ML techniques—spanning supervised, unsupervised, and reinforcement learning—to develop, validate, and analyze healthcare-specific data models and synthetic data cohorts that drive meaningful outcomes for Veterans. This role sits at the intersection of data science innovation and mission-driven public service, contributing directly to the VA's strategic goal of becoming an AI-enabled enterprise.

The ideal candidate is a self-directed, collaborative problem-solver who thrives in complex, matrixed federal environments and can translate sophisticated data science concepts into actionable insights for both technical and non-technical stakeholders. You bring deep intellectual curiosity about healthcare data, a commitment to responsible AI practices, and the ability to mentor and guide citizen developers as they build and scale AI solutions.
