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.
Puede obtener más detalles sobre la naturaleza de esta vacante y lo que se espera de los solicitantes leyendo la información a continuación.
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:
o Work in small, iterative steps
o Use light-weight artefacts (sketches, prototypes)
o Validate assumptions quickly with users and data
* Collaborate with Product, Engineering, Data/AI and Business to:
o Understand user needs, pain points and business goals
o Define problem statements, hypotheses and success metrics
o 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:
o Analyse quantitative data (e.g. funnels, experiments, dashboards)
o Plan and run user tests and other qualitative research formats
o 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):
o Facilitate workshops, design reviews and alignment sessions
o Provide feedback and coaching to other designers
o 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:
o End-to-end product design (from problem framing to shipped solutions)
o Complex flows and interaction/service design, not just visual polish
o Clear visual design skills (layout, hierarchy, typography, visual clarity)
o Measurable impact on user and/or business outcomes where possible
* Proven experience with Lean UX:
o Hypothesis-driven, iterative working style
o Close collaboration with Product and Engineering
o Focus on outcomes and learning over deliverables
o 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
