Tennis Channel is building a high-quality Direct-to-Consumer (DTC) streaming platform across mobile, hybrid, and living room devices. As we scale, we need someone who can own and elevate our test automation infrastructure, embedding intelligence and AI support into our QA workflows. As the SDET, you'll be the first test automation engineer responsible for architecting and building automation frameworks, integrating AI/ML tools for test generation or validation, and ensuring high-quality releases across iOS, Android, hybrid (React Native), and backend systems. You'll set up the foundation of how we ship software reliably across platforms, collaborating deeply with product, development, and operations to ensure we release with confidence. You'll bring creativity to quality; leveraging AI, automation, and tooling to dramatically reduce manual effort; while having strong ownership within a small, agile team where your decisions and contributions directly impact product quality. In this early-stage environment, you'll also help define the culture of engineering and quality as we build a world-class streaming experience from the ground up. This role is onsite and located in Seattle, WA.
