Your Tasks As a (Senior) UX/UI Designer – Digital Products, you design intuitive, effective and visually clear experiences across our digital ecosystem (web, app and internal applications). You apply a Lean UX mindset – working iteratively, testing assumptions early and focusing on measurable outcomes rather than heavy documentation. You collaborate closely with Product, Engineering and Data/AI to define problems, test hypotheses and ship solutions grounded in data, user research and continuous feedback – for both human users and AI/synthetic users (e.g. automated agents or AI-powered systems). Depending on your experience, you will either grow into or already take on a senior role with greater ownership, stakeholder alignment and mentoring responsibilities. - Own and drive the end-to-end UX and UI design process for selected digital products and features (from discovery to delivery) - Apply Lean UX principles: - Work in small, iterative steps - Use light-weight artefacts (sketches, prototypes) - Validate assumptions quickly with users and data - Collaborate with Product,
