Roku is seeking a Senior QA Automation Architect to help evolve test automation capabilities from primarily AV-sync testing into broader audio quality coverage across Roku TVs, soundbars, and headphones. In this role, you will partner closely with the team lead to architect and advance the automation ecosystem, with a strong emphasis on AI-driven innovation through internal initiatives. You will design and implement test analysis systems that identify quality gaps, predict failure patterns, and optimize test effectiveness across products.
You will establish new methodologies for measuring and improving test quality beyond simple pass/fail metrics, focusing on regression prevention and production reliability.
The ideal candidate brings deep expertise in test architecture, embedded systems automation, and AI-powered quality assurance, and is excited to drive meaningful transformation in how Roku tests and delivers audio experiences.
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.

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.
