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? Roku’s Developer Platform team builds tools and embedded capabilities that help channel partners develop, tune, and debug high-quality apps. The team works across web applications, APIs, and platform services to improve the end-to-end developer experience and support partner success at scale. What is the role? Roku is looking for a Senior Full Stack Engineer to join the Developer Platform team and build AI-enabled web applications and services that improve app development and management workflows. This role will design and deliver full stack solutions that support external partners and internal stakeholders across the Roku ecosystem. You will contribute across frontend and backend systems, with a strong focus on reliability, scalability, and usability. You will build and evolve APIs and microservices, and help integrate modern AI capabilities into production experiences where they add clear user value. The role requires strong technical judgment, cross-functional collaboration, and the ability to move from concept through delivery in a fast-paced environment. You will join a high-performing team with a strong delivery culture and a commitment to building practical, high-impact developer tools. 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 you have built fluency across the agentic engineering toolchain — coding harnesses like Claude Code or Cursor, MCP servers, custom skills, or agent frameworks — and 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. What are the responsibilities of the role? • Design and build full stack web applications using React and Node.js • Integrate AI capabilities including LLM-driven experiences where appropriate • Develop APIs and microservices that connect tools, data, and platform workflows • Deploy, scale, and monitor services in cloud environments using Kubernetes • Build robust, highly available backend and frontend systems for developer-facing use cases • Collaborate with cross-functional teams to define and deliver partner and internal tooling • Troubleshoot production issues and improve performance and reliability • Participate in code reviews and contribute to engineering best practices What experience would help someone be successful in this role at Rok
