Roku operates a public streaming television platform spanning hardware (TVs, players, audio), software (Roku OS), and content distribution (The Roku Channel reaching ~80M households). The tech stack—Kubernetes, Istio, Java, C++, Spark, Airflow—reflects a systems-heavy, data-intensive operation; hiring is heavily weighted toward engineering and product roles. Active projects and pain points center on ad performance measurement, real-time ad serving, and yield optimization, signaling that monetization through advertising (not subscription) is the core business lever.
