Job description

Teamwork makes the stream work.

Roku is changing how the world watches TV

Roku is the #1 TV streaming platform in the U.S., Canada, and Mexico, and we've 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, 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.

What does the team work on?

The Revenue Automation and Data team is a key part of Roku's Advertising organization, driving financial automation and data solutions that enable informed decision-making across the advertising ecosystem. We work in a fast-paced, complex environment and partner closely with Finance, Accounting, Analytics, and multiple engineering teams to deliver timely, high-impact insights into business performance. As we look ahead, we're investing in AI-powered capabilities to exponentially scale financial workflows and help non-technical stakeholders translate our diverse data assets into actionable outcomes.

What is the role?

We are seeking a highly skilled Senior Software Engineer for this hybrid position which bridges software and data engineering, requiring the ability to design, build, and maintain scalable systems for both application development and large-scale data processing. In this role, you will architect and maintain production-grade data products and APIs, leveraging technologies such as Java/Scala, SQL, Spark, Airflow, and Kubernetes to deliver reliable, high-performance solutions. You will collaborate with cross-functional partners across Finance, Accounting, and Analytics to translate complex business requirements into robust technical solutions. The role involves driving data quality and operational excellence across the full lifecycle of data pipelines and backend services. You will also contribute to the team's AI-powered initiatives, helping to scale financial workflows and unlock actionable insights from diverse data assets. The successful candidate has a proven track record building high-scale data services and pipelines, with strong engineering rigor and a passion for continuous improvement.

How will I use AI at Roku?

At Roku, we don't just use AI, we work with it. AI agents and smart tools help power drafts, analysis, and repetitive workflows, while our people bring direction, judgment, and accountability.

We're looking for curious, adaptable builders who can show how they've used AI or automation to move faster, raise the bar, and scale their impact. We value your AI skills if have built fluency across the agentic engineering toolchain — coding harnesses like Claude Code or Cursor, MCP servers, custom skills, or agent frameworks. And you can describe projects where you shipped real work with these tools. You know how to drive an agent, verify its output, and ramp on an unfamiliar codebase with an agent helping you.
