Roku pioneered streaming to the TV, and 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 you’ll make a valuable, and valued, contribution. We’re 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 role

Roku is looking for a Sr. Data Scientist to join the Core Analytics team supporting our Viewer Product. This role leverages data analytics to support and improve our Live product. You will own end‑to‑end analytics that shape how viewers discover, engage with, and return to Live experiences on Roku. You will work closely with product management and engineering to identify opportunities to create new features, drive their adoption, and generate value for Roku. This individual will investigate and develop solutions to track, monitor, and improve our ecosystem. The successful candidate is quantitatively driven, detail‑focused, and possesses an elevated level of problem‑solving expertise.

What you’ll be doing

• Analyze structured and unstructured data and communicate insights to help stakeholders solve business problems, identify trends, and make data‑driven decisions.
• Advise on key product development strategy decisions to drive our Live product experience.
• Develop and maintain dashboards, reports, and data visualizations to monitor key metrics for operational and systems health.
• Develop necessary data pipelines to power automation, validation, and reporting.
• Collaborate with stakeholders to align data science initiatives with organizational goals and strategy; design and execute A/B tests.
• Perform exploratory data analysis on emerging trends and execute advanced analysis across the Roku Platform.
• Provide feedback directly to leadership on performance of various initiatives and untapped opportunities.

We're excited if you have

• 4 years of work experience with a bachelor’s or master’s degree in a quantitative field (e.g., Statistics, Business Analytics, Data Science, Mathematics, Economics, Engineering, or Computer Science).
• 4 years of experience in product analytics; experience with platforms in the media and entertainment industry preferred.
• Expertise in SQL, SAS, R, Python, or another programming language to query data and perform analysis.
• Demonstrated ability to influence quantitatively meaningful business outcomes.
• Hands‑on experience with visualization tools like Tableau or Looker.
• A bias towards action in resolving issues and operating in a high‑energy, fast‑paced environment.
• Hands‑on experience in A/B testing and statistical modeling/forecasting.

This role can be based in either Cambridge or Manchester. You are required to work in the office for 4 days per week—that is the core requirement of the role.

Our Hybrid Work Approach

Roku fosters an inclusive and collaborative environment where teams work in the office Monday through Thursday. Fridays are flexible for remote work except for employees whose roles require them to be in the office five days a week or who are in offices with a five‑day in‑office policy.

Benefits

Roku offers a diverse range of benefits as part of our compensation package to support our employees and their families. Our comprehensive benefits include global access to mental health and financial wellness support and resources. Local benefits may include healthcare (medical, dental, and vision), life, accident, disability, commuter, and retirement options (401(k)/pension). Employees can take time off work for vacation and other personal reasons to balance evolving work and life needs. Not every benefit is available in all locations or for every role; for specific details, consult with your recruiter.

The Roku Culture

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