Roku is changing how the world watches TV

Roku is the #1 TV streaming platform in the U.S., Canada, and Mexico, and weve set our sights on powering every television in the world. Roku pioneered streaming to the TV. Our mission is to be the TV streaming platform that connects the entire TV ecosystem. We connect consumers to the content they love, enable content publishers to build and monetize large audiences, and provide advertisers unique capabilities to engage consumers.

From your first day at Roku, youll make a valuable - and valued - contribution. Were a fast-growing public company where no one is a bystander. We offer you the opportunity to delight millions of TV streamers around the world while gaining meaningful experience across a variety of disciplines.

About the team

Our Data Science team is a high-impact research team actively shaping the future of TV, using Big Data to build and enhance the user experience on the Roku streaming platform. Our production-ready machine learning models and statistical solutions optimize the user experience across all of Rokus core business models and products, and our scientists engage closely with business, product, and engineering leaders to make material and measurable impacts on the success and growth of the platform.

About the role

As a Senior Research Data Scientist on Rokus 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 California Only - The estimated annual base salary for this position is between $203,800 - $323,700. 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 youll 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 Rokus 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

Were excited if you have

• PhD in Economics, Econometrics, Statistics, or a closely related quantitative field with a strong emphasis on causal inference
• 10+ years of experience applying causal inference and machine learning methods to real-world problems, with a demonstrated track record of measurable impact
• Deep expertise in observational causal methods such as propensity score matching, Double Machine Learning, doubly robust estimation, instrumental variables, and difference-in-differences
• Experience building reusable causal inference tools or platforms beyond one-off analyses
• Proficiency with Spark, Ray, SQL, Python, and ML frameworks such as scikit-learn, XGBoost, and LightGBM
• Experience with terabyte- or petabyte-scale datasets in distributed computing environments
• Strong communication skills with the ability to translate econometric findings into clear business recommendations
• Technology industry experience; connected TV, streaming, or advertising experience is a plus

What should I know about Rokus culture?

Roku is a great place for people who want to work in a fast-paced environment where everyone is focused on the companys success rather than their own. We try to surround ourselves with people who are great at their jobs, who are easy to work with, and who keep their egos in check. We appreciate a sense of humor. We believe a fewer number of very talented folks can do more for less cost than a larger number of less talented teams. Were independent thinkers with big ideas who act boldly, move fast and accomplish extraordinary things through collaboration and trust. In short, at Roku youll be part of a company thats changing how the world watches TV.

We have a unique culture that we are proud of. We think of ourselves primarily as problem-solvers, which itself is a two-part idea.

That penchant for action gives us a pragmatic approach to innovation, one that has served us well since 2002.
