- Research open-ended healthcare and provider-data challenges, form hypotheses, and develop action plans and analytical approaches to turn findings into actionable solutions
- Develop novel algorithms to solve complex or unprecedented problems
- Evaluate and improve existing models and algorithms to increase accuracy, performance, scalability, and reliability, and measure the resulting business impact
- Perform large-scale data processing and analysis using Python, SQL, Databricks, Spark, and distributed computing across structured and unstructured datasets
- Develop and maintain automated systems for anomaly detection, data validation, feature engineering, and continuous model monitoring
- Design feature engineering strategies and evaluate model performance using appropriate validation techniques
- Evaluate and integrate third-party data sources, tools, and vendors to strengthen our datasets and analytical capabilities
- Partner with Engineering to productionize models and build scalable, reliable solutions within our software products
- Apply LLM tools such as Claude to accelerate analysis, automate workflows, and improve documentation, and explore opportunities in generative AI, NLP, and AI agents

- Participate in cross-functional initiatives and support client-facing analytics discussions as needed
What You'll Need:
Experience in one or more of these areas would be especially valuable:
- Healthcare provider data, provider networks, or healthcare analytics
- Healthcare, SaaS, or another highly regulated data environment
- Integrating ML models into production software products
- Data quality, entity resolution, anomaly detection, or large-scale data validation
- Generative AI, NLP, LLM applications, or agentic workflows
