The Opportunity

Livongo is the leading applied health signals company, partnering with over 800 clients to serve more than 250,000 members. The Data Science team at Livongo works closely with product managers, clinicians and engineers to improve the health of people living with chronic health conditions using advanced modeling and machine learning.

This role is focused on better understanding our members and helping them improve their health outcomes across our supported chronic conditions. Projects will range from causal analysis of observational studies to advanced ML models to predict the dynamics of physiological time series like blood glucose, blood pressure, body weight and behavioral health.


  • Quantify the impact of Livongo products on member health and identify areas to improve outcomes.
  • Develop insights and models that enable the whole company to understand our members and drive better product decisions.
  • Use advanced machine learning approaches to enhance Livongo product/program and improve member experiences and clinical outcomes. This includes formulating business and product needs as machine learning problems; use technical rigor to identify the techniques and algorithms to pragmatically solve problems related to Applied Health Signals, member insights, and behavioral recommendations. The domains include modeling clinical outcomes/metrics, clinical risks, NLP, behavior change.
  • Use Python, Tensorflow, PyTorch, and Keras to conduct both exploratory analyses and production modeling using both traditional and deep-learning techniques. This includes feature engineering, unsupervised learning, supervised learning, reinforcement learning.
  • Explore and identify new types of signals and models to better understand our members using data from diverse sources, including hardware and mobile sensor data, audio and text data, image data, and clinical and pharmacy data.
