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, Engineering, Data/AI and Business to:

- Understand user needs, pain points and business goals
- Define problem statements, hypotheses and success metrics
- 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
- Create wireframes, interaction concepts and low- to high-fidelity prototypes; 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
- Systematically integrate user feedback and insights into product decisions and iterations

- Design for both human users and synthetic users (e.G. AI agents, scripts, systems interacting with your interfaces), ensuring robust, well-defined interaction contracts
- Contribute to and evolve our design system, patterns and guidelines, ensuring consistency across platforms and teams
- As a senior (depending on level):

- Facilitate workshops, design reviews and alignment sessions
- Provide feedback and coaching to other designers
- Help improve UX practices, processes and ways of working across teams

Your Profile

- Several years of experience in UX/UI design for digital products (web/app/tools) in a fast-paced, agile environment
- Bachelor's or Master's degree in Design, Human–Computer Interaction or a related field, or equivalent practical experience
- Strong portfolio demonstrating:




- End-to-end product design (from problem framing to shipped solutions)
- Complex flows and interaction/service design, not just visual polish
- Clear visual design skills (layout, hierarchy, typography, visual clarity)
- Measurable impact on user and/or business outcomes where possible

- Proven experience with Lean UX:

- Hypothesis-driven, iterative working style
- Close collaboration with Product and Engineering
- Focus on outcomes and learning over deliverables
- Proficiency with modern design and prototyping tools (e.G. Figma, Sketch, Adobe CC, Axure, Framer, Principle or similar)

- Strong data mindset: confident in interpreting quantitative data, planning and evaluating user tests, and turning insights and feedback into concrete design decisions
- Solid AI literacy: understanding of AI/ML in products (e.G. recommendations, generative AI, assistants) and their UX implications (trust, transparency, control)
- Hands‐on experience using AI tools in your design workflow and the judgment to know when human expertise must lead
- Interest or experience in designing for non‐human/synthetic users (e.G. AI agents, scripts, APIs) is a plus
- Strong communication skills in English; German is a plus
- Enjoy working in an international, multidisciplinary environment and contributing to a strong, collaborative team culture
- For the senior level: proven end‐to‐end ownership, ability to influence beyond your immediate product area, and experience mentoring other designers
