About Humana and Stars Analytics

Humana is committed to advancing health outcomes through innovative analytics and continuous learning. The CAHPS & HOS Analytics team, part of Stars Analytics, drives survey performance and member experience by integrating actionable insights, predictive modeling, and reliable measurement.

The Lead Data Scientist (Experimentation) designs and operates the learning engine of the CAHPS & HOS teams, ensuring actions produce reliable learning. This role owns study design and measurement strategy across CAHPS & HOS, builds lightweight testing frameworks, and accelerates feedback loops to ensure every action becomes an opportunity to generate insight, reduce uncertainty, and improve future decisions.

The Lead Data Scientist (Experimentation) is responsible for developing and maintaining robust study designs and measurement strategies for interventions impacting CAHPS & HOS. This role partners with operations teams and external vendors to ensure sound methodology and rapid, continuous measurement for pilots and interventions. The Lead Data Scientist (Experimentation) creates and manages lightweight A/B testing frameworks and a learning inventory, enabling early and consistent measurement of causal impact.

This position exercises independent judgment and decision‑making on complex issues regarding study design, analytics, and learning strategies, working under minimal supervision to ensure that insights reliably drive action and improvement.

• Study Design & Measurement Strategy: Develop and own rigorous study designs and measurement plans for CAHPS & HOS interventions, pilots, and programs.

• Experimentation Frameworks: Build, maintain, and scale lightweight A/B testing frameworks to facilitate rapid, consistent experimentation and learning.

• Learning Inventory: Create and maintain a centralized inventory of experiments, insights, and learnings to support organizational knowledge and strategy.

• Collaboration: Partner with operations teams and external vendors to ensure methodological integrity and effective, continuous measurement.

• Impact Measurement: Conduct early and consistent evaluation of causal impact, ensuring actionable insights are generated and communicated to stakeholders.

• Continuous Improvement: Iterate on study and measurement approaches to accelerate feedback loops and reduce uncertainty in decision-making.

• Bachelor’s degree in Data Science, Statistics, Epidemiology, or related field.

• 5+ years of experience in study design, experimentation, or applied data science.

• Expertise in A/B testing, causal inference, and measurement strategies.

• Proficiency in programming languages and statistical tools (e.g., Python, SQL).

• Demonstrated ability to articulate ideas effectively in both written and oral forms with strong collaboration skills.

• Ability to work independently and exercise sound judgment on complex analytic issues.

• Master’s degree or PhD in a quantitative discipline.

• Experience in healthcare analytics, survey research, or Stars performance measurement.

• Familiarity with automation tools for experiment workflow.

• Knowledge of learning design principles and rapid feedback methodologies.
