What is a Data Scientist at Roku?
A Data Scientist at Roku plays a critical role in shaping the user experience and driving business growth for millions of active streaming devices worldwide. Operating at the intersection of product, engineering, and business strategy, data scientists at Roku translate massive datasets into actionable insights that directly influence content discovery, user engagement, and platform monetization. Whether optimizing the home screen layout or refining ad-targeting algorithms, your work will have a tangible impact on how users interact with digital media.
Within the organization, data science teams are often embedded or aligned with specific product areas, such as the Personalization & Recommendations group. In these specialized roles, you will design, deploy, and analyze machine learning models and statistical frameworks that power Roku's content recommendation engines. Because the platform operates at an immense scale, the technical challenges are highly complex, requiring a sophisticated balance of data engineering efficiency, statistical rigor, and sharp product intuition.
Ultimately, Roku looks for data scientists who do not just build models in isolation but can act as strategic partners to product managers and software engineers. Successful candidates are those who can seamlessly transition from writing complex SQL queries and designing rigorous A/B tests to presenting high-level strategic recommendations to senior leadership.
