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:
Use light-weight artefacts (sketches, prototypes)
Validate assumptions quickly with users and data
Collaborate with Product, Engineering, Data/AI and Business to:




Prioritise and plan design work within the product roadmap
Design user journeys, flows and interactions across touchpoints (web, app, tools) to ensure a coherent, frictionless experience
deliver final UI aligned with our brand, design system and accessibility standards
Use AI-assisted tools (e.g. for ideation, variants, UX copy, localisation, research synthesis) to work efficiently – and critically evaluate and refine their output
Design and refine AI- and data-enabled features (e.g. search, recommendations, personalisation, assistants or smart tooling) with a strong focus on transparency, user control and trust
Work data-driven:
Analyse quantitative data (e.g. funnels, experiments, dashboards)
Plan and run user tests and other qualitative research formats
Design for both human users and synthetic users (e.g. Contribute to and evolve our design system, patterns and guidelines, ensuring consistency across platforms
