Phd Causal Inference Jobs in Cambridge, MA (NOW HIRING)

At WHOOP, we're on a mission to unlock human performance and healthspan. WHOOP empowers users to perform at a higher level through a deeper understanding of their bodies and daily lives.

We are seeking a Senior Research Scientist to lead hypothesis‑driven research that translates continuous physiological data into meaningful, real‑world insights. You will work at the intersection of data science, human physiology, and product innovation, and will focus on understanding how health, behavior, and context interact over time at the individual and population level.

The ideal candidate will design and execute research that goes beyond detection to model trajectories, variability, and individual response patterns to enable more accurate and actionable insights.

• Lead end‑to‑end research projects from hypothesis formulation through analysis, interpretation, and communication.
• Analyze large‑scale, longitudinal physiological and behavioral datasets to identify meaningful patterns and insights.
• Develop and evaluate models that characterize individual variability and predict future physiological states.
• Translate research findings into clear, actionable recommendations that inform product direction and algorithm development.
• Collaborate closely with product, engineering, and data science teams to ensure research is interpretable and aligned with real‑world use cases.
• Contribute to the design and execution of research programs.
• Produce high‑quality scientific outputs, including internal reports, white papers, and peer‑reviewed publications.
• Serve as a senior technical leader, providing guidance and mentorship to junior scientists and contributing to raising the bar for scientific rigor across the team.
• Help define research standards, methodologies, and best practices across the team.

• PhD (or equivalent experience) in a quantitative or health‑related field (e.g., Epidemiology, Biostatistics, Biomedical Engineering, Neuroscience, Computer Science, or related disciplines).
• Strong background in health science, with grounding in public health and clinical concepts, and experience modeling longitudinal or time‑series data (e.g., within‑person variability in real‑world settings).
• Demonstrated ability to design hypothesis‑driven analyses and translate findings into clear conclusions.
• Proficiency in statistical modeling and/or machine learning methods and demonstrated experience using Python or R.
• Significant hands‑on experience with advanced modeling techniques for longitudinal/time‑series data, such as probabilistic methods, Bayesian inference, and/or causal inference.
• Ability to work across disciplines and communicate effectively with both technical and non‑technical stakeholders.
• Experience connecting data analysis to real‑world applications (product, wellness, clinical, or operational).
• Strong written and verbal communication skills.

This role is based in the WHOOP office located in Boston, MA. The successful candidate must be prepared to relocate if necessary to work out of the Boston, MA office.
