It takes an entire team of passionate and caring people, united in our mission to put the senior first.We have built a team of talented and experienced people who are passionate about transforming the lives of the seniors we serve. In this fast-growing company, you will find ample room for growth and innovation alongside the Alignment Health community. Working at Alignment Health provides an opportunity to do work that really matters, not only changing lives but saving them. Together. Alignment Healthcare is a data and technology driven healthcare company focused on partnering with health systems, health plans, and provider groups to provide care delivery that is preventive, convenient, coordinated, and that results in improved clinical outcomes for seniors. We are seeking a mission-driven Data Scientist to join our growing Stars team, with a primary focus on HOS (Health Outcomes Survey) — the functional health and outcomes survey component of our Star Ratings strategy. This role is responsible for modeling member-level physical and mental health trajectories, identifying the clinical and operational drivers behind HOS measure performance, and translating those insights into targeted interventions that move specific Star Rating cut points. This is a unique opportunity to work at the intersection of healthcare, clinical outcomes, and survey methodology — directly shaping the strategy behind one of the most influential and least understood components of the Star Ratings program.GENERAL DUTIES/RESPONSIBILITIES:
- Collaborate with Stars, clinical, and care management leaders to understand HOS performance drivers and translate them into analytical solutions.
- Segment members by likelihood to respond to the HOS survey and by predicted physical or mental health trajectory, to prioritize outreach and intervention.
- Build and fine-tune models predicting member-level risk of HOS composite decline, including Improving/Maintaining Physical Health, Improving/Maintaining Mental Health, Monitoring Physical Activity, and Reducing the Risk of Falling.
- Analyze item-level HOS survey data, not just composite scores, to isolate which specific survey questions are driving measure performance.
- Build pipelines that track HOS survey administration cycles — baseline and follow-up cohorts, sampling, fielding, and response rates — and validate case-mix adjustment logic against CMS methodology.
- Model statistical significance and year-over-year variance to distinguish genuine performance shifts from survey noise or sampling error.
- Coordinate with HOS survey vendors on cohort tracking, sampling methodology, fielding timelines, and case-mix adjustment specifications.
- Collaborate with engineering teams to version, test, and deploy models using Git, CI/CD pipelines, and virtual machine (VM) environments.
- Partner with clinical, care management, complex case management, Compliance, and Legal teams to ensure HOS-related data outputs and interventions align with CMS guidance.
