About the role
As a Senior Research Data Scientist on Roku's Data Science team, you will lead the development of a best-in-class causal inference platform that measures and optimizes the true incremental impact of customer actions, product features, and business interventions on long-term outcomes. Partnering with the Customer Growth organization, you will build the methods and systems that enable Roku to make high-confidence decisions from observational data when randomized experiments are not feasible. You will own the full lifecycle of causal measurement—from gathering business requirements and defining estimation approaches, to partnering with Engineering to productionize scalable causal pipelines and communicating findings to senior leadership. Your work will directly inform growth, retention, and monetization strategy across the platform, making this role ideal for an applied economist or econometrician who excels at the intersection of rigorous research and production engineering. This is someone equally comfortable deriving identification strategies and building estimators on terabyte-scale data. For Massachusetts Only - The estimated annual base salary for this position is between $181,200 - $229,500. Compensation packages are based on factors unique to each candidate, including but not limited to skill set, certifications, and specific geographical location. This role is eligible for health insurance, equity awards, life insurance, disability benefits, parental leave, wellness benefits, and paid time off.
What you'll be doing
Design, build, and productionize a causal inference platform that standardizes how Roku measures the incremental impact of customer actions and business decisions Research and implement causal estimation methods, including heterogeneous treatment effects, tailored to Roku's data and business questions Build long-term outcome frameworks that enable impact projection from limited observation windows Develop diagnostic and validation standards at scale to ensure credibility of causal estimates Leverage AI to create counterfactual scenarios and build tools that help users run, understand, and act on causal estimates correctly Work cross-functionally with Data Engineering, Product Management, and Core Analytics to translate business questions into well-defined causal problems and deploy production-ready solutions Contribute to the technical vision of the Data Science team and the broader research agenda across causal inference, predictive modeling, and experimentation
