DeepL is hiring a senior full-stack engineer for its Voice team, which builds real-time interpretation products. The role covers one surface end to end: problem definition, architecture, delivery and production operation, working with researchers, product managers and designers on requirements that shift as research moves. The posting asks for experience with real-time systems such as WebRTC, WebSockets or streaming architectures, React and TypeScript on the frontend and C# on the backend, plus comfort with ambiguity and mentoring. It describes a zero-to-one environment building models, streaming architecture and interfaces in house rather than wrapping an API.
