Senior Software Engineer, Embedded UI

As a Senior Software Engineer on the OS UI/SDK team, you will design, develop, and deliver engaging platform features - including screensavers, static and dynamic wallpapers, trivia, featured experiences, and AI-driven content initiatives - that reach millions of Roku users worldwide. You will leverage AI and machine learning technologies to develop new capabilities that enhance user experiences across the Roku platform. This role requires a proactive, ownership-driven approach where you will create proof-of-concept prototypes in a startup-minded environment and then adapt those prototypes for production-grade deployment. You will collaborate closely with cross-functional partners in UI/UX design, product management, backend engineering, and business leadership to translate ideas into impactful solutions. You will investigate, diagnose, and resolve technical issues to maintain high-quality, commercially viable products. This is an opportunity to shape the future of streaming entertainment through innovation and a deep commitment to engineering excellence., 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 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., * Design and develop features for new experiences on the Roku platform, including screensavers, wallpapers, trivia, and featured experiences
