What does the team work on?
Roku's Automation support and Tools team focuses on providing innovative, impactful tools and SW solutions including AI enabled engineering capabilities to help accelerate validation efforts, improve efficiency, enhance productivity of all engineering team across Roku's entire embedded SW org. The team works across full-stack applications, backend services, and scalable platform services to improve developer productivity, end-to-end testing experience of Roku products and services. You will be joining a talented, high-performance team of developers with a strong delivery culture. We are looking for someone who can help us keep up this pace and continue delivering high quality as we grow.
What is the role?
Roku is looking for a Senior Software Engineer to join the Embedded Software Automation and Tools team to build full stack applications and services that support end-to-end automation and test infrastructure. This role involves designing and delivering full stack solutions that support cross-functional internal and external stakeholders across the Roku ecosystem. You will contribute across frontend and backend systems, with a strong focus on performance, reliability, and scalability. 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.
How will I use AI at Roku?
At Roku, we don't just use AI, we work with it. We use AI agents and smart tooling across brainstorming, planning, analysis, and implementation. People set the direction, exercise judgment, and own the outcomes.
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 agentic frameworks — and can describe projects where you shipped real customer-facing work with these tools. You know how to drive an agent, validate its output, and ramp on an unfamiliar codebase with an agent helping you.
