• Design, develop, optimize, and scale machine learning models and advanced analytics solutions to improve provider data quality and generate meaningful network insights
• Apply statistical modeling, predictive analytics, and machine learning techniques (classification, regression, clustering, NLP, anomaly detection) to solve business problems
• 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
• Develop and maintain metrics to evaluate model performance, data quality, and business impact
• Translate complex findings into clear, actionable insights for technical and non-technical stakeholders
• Present findings and recommendations to Network Analytics leadership and broader company audiences
• Partner with Product and business teams to identify opportunities for new features, metrics, and data-driven solutions
• Mentor other data scientists and analysts, and contribute to technical standards, data governance, and MLOps best practices
• Participate in cross-functional initiatives and support client-facing analytics discussions as needed

What You'll Need:

• 7+ years of experience in data science, machine learning, or advanced analytics, preferably in a SaaS organization
• Master's degree in Data Science, Computer Science, Statistics, Mathematics, or a related discipline, or equivalent relevant experience
• Demonstrated experience building and delivering machine learning models into production
• Advanced Python skills, including tools such as pandas, NumPy, and scikit-learn
• Strong experience with Databricks, Spark, or comparable distributed computing technologies
• Advanced SQL skills
• Experience with ML frameworks such as TensorFlow, PyTorch, or similar technologies
• Strong understanding of machine learning techniques including classification, regression, clustering, NLP, and anomaly detection
• Strong applied statistics knowledge, including hypothesis testing, regression analysis, and probability
• Experience working with large, messy, and complex datasets
• Understanding of MLOps, including deployment, monitoring, validation, and model lifecycle management
• Experience using LLMs and AI-assisted tools to improve data science workflows
• Ability to independently tackle ambiguous problems and determine an effective path forward
• Ability to explain complex technical findings in a way that creates clear business value
• Strong collaboration skills and experience working across Product, Engineering, Data, and business stakeholders
• Experience leading technical initiatives and mentoring others
• 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
  • Data visualization and communicating analytical results to clients or executive audiences
