This senior position is responsible for designing and implementing scalable, end-to-end data science solutions that enhance risk score accuracy, support regulatory compliance, and drive financial performance across Medicare Advantage, ACA, and Medicaid programs. Using Python and cloud-based analytics platforms, the Data Scientist develops and manages machine learning models to forecast risk, identify outreach opportunities, and evaluate program effectiveness.
The role requires deep expertise in healthcare data (e.g., claims, encounter, enrollment), strong knowledge of HCC risk adjustment methodologies, and the ability to translate complex analytical outputs into actionable insights for both technical and executive audiences. As a thought leader, the Data Scientist collaborates across clinical, actuarial, and operational teams, mentors junior data scientists, and fosters a data-driven culture to support innovation and strategic decision-making across the organization.
Job
This individual contributor is primarily responsible for designing and developing data pipelines and automation for data acquisition and ingestion of raw data from multiple data sources and data formats by transforming, cleansing, and storing data for consumption. This role is also responsible for developing detailed problem statements outlining hypotheses and their effect on target clients/customers, analyzing and investigating complex data sets and summarizing key characteristics, selecting, manipulating and transforming data into features used in machine learning algorithms, training statistical models, deploying and maintaining reliable and efficient models through production, verifying model performance, and collaborating with internal and external stakeholders across domains to develop and deliver statistical driven outcomes.
