As a Senior Software Engineer on our Web & API team, you will play a key role in shaping and evolving our e-commerce storefront. Working across the full stack, from React components and data integrations to AI-powered features, you will take ownership of complex features end-to-end, from specification and architecture through to delivery and monitoring. In close collaboration with Product and Design in an agile environment, you will combine a keen eye for performance with a drive to build experiences that delight millions of customers. Your curiosity for emerging technologies will help the team work smarter, ship faster, and continuously push the boundaries of what is possible. This position is permanent and based in Munich.

A sharp focus on performance across the stack, from frontend rendering to backend data fetching, including server-side rendering (ideally with React Router) and GraphQL
