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? This team spends most of its time building and improving the UI framework and components that power Roku user experiences. Our roadmap helps us accelerate our growth and scale, putting surprising new features into the hands of tens of millions of Roku users worldwide. Our developers and engineers are owners. They are motivated from within, finding and taking on a feature or project simply because that problem needs to be solved and shipped. But that individual must work together with different engineering teams, UI design, product teams, and business leadership to make things happen, which means that engineers succeed here because they can maintain that independent spirit and motivation within a deeply collaborative environment. We are the pragmatic dreamers inventing and re-inventing the world of streaming media. What is the role? Roku pioneered streaming to the TV and continues to innovate and lead the industry. The Senior Software Engineer will contribute extensively to the embedded UI framework development, working closely with system architects to develop new features and extend current capabilities to improve system stability and performance. This role involves building and maintaining tools to improve the quality and consistency of Roku OS logging data, creating Python-based automation to extract, analyze, and validate log usage across large codebases, and developing offline pipelines for processing logs to support pre-merge validation and automated data contract generation. You will write and review C++ changes in embedded codebases to ensure accurate and reliable logging, and partner with UI infrastructure, firmware, and CI teams to integrate tooling into developer workflows. The features and performance improvements you implement directly impact millions of users every day, making this a great opportunity for an experienced professional who has innovative ideas for complex problems and can translate these ideas into ultra-reliable software. How will I use AI at Roku? At Roku, AI agents do most of the keystroke-level coding. Engineers act as the technical leads for those agents — setting context, planning work, verifying outputs, and recovering when the agent goes off course. If you are excited about working this way, we want to talk to you. You 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. At Roku, we're embracing AI as a powerful tool to amplify human creativity, accelerate innovation, and deliver better results for our customers.
