Roku is hiring a senior software engineer for its Entertainment Assistant team, which builds conversational AI across Roku devices. The role is hands-on: owning fulfilment-ranking pipelines, an offline evaluation platform using LLM-as-judge harnesses, the assistant's LLM agent with tool routing and retrieval, caching, and observability for cost and latency. Roku asks for strong production engineering, ownership of ML infrastructure or model delivery, and knowledge of the ML lifecycle. It also expects fluency with agentic coding tools and evidence of AI-assisted engineering.
