At Roku, the UI team builds the foundational frameworks, tooling, and high‑performance UI components that power experiences across millions of devices. We own the middleware and UI layers that enable smooth navigation, responsive interactions, rich animations, and consistent developer workflows across the platform. Our work spans graphics rendering, layout and animation systems, performance optimization, and developer APIs that make it easy to create reliable, visually compelling applications at scale. We operate in a collaborative, high‑trust environment and partner closely with firmware, platform, and product teams to ensure the end‑to‑end experience is fast, robust, and ready for what’s next.
As a Senior Software Engineer on the UI team, you’ll design, implement, and optimize systems that underpin Roku’s user experience and developer platform. You’ll work on performance‑critical code paths for graphics rendering, animation, layout, and UI frameworks, ensuring buttery‑smooth visuals and instant responsiveness across a wide range of devices. You’ll help shape core architecture, collaborate across the stack with hardware, firmware, and application teams, and see your work directly impact tens of millions of users. This role is ideal for engineers who love deep technical problem‑solving, care about performance down to the last millisecond, and want to build the invisible foundations that make great user experiences possible.
