Your work will ensure that the user experience of our products is consistent, accessible, and aligned with customer and business needs, from initial discovery and concept through to high-fidelity prototypes and design specifications. This includes driving workshops, collecting feedback through usability testing, and iterating designs based on insights and analytics.

Main tasks

  • Identifying opportunities for the business through research findings and usage data

  • Guiding teams in shaping and implementing state-of-the art solutions whether that is new platforms or new features

  • Demonstrate the value and impact of a user-centred design process by applying your hands-on design skills

  • Create wireframes, mockups, prototypes, and final visual designs for core flows

  • Bring user insights into decision-making via usability testing, stakeholder feedback, and analytics reviews.

  • Prepare screen flows and design assets ready for development handover, including responsive behaviour and edge-case handling.

Your Profile

You will have:

  • 5+ years of professional experience in User Experience (UX) design, resulting in a portfolio that demonstrates:

  • A broad design skillset ranging from conceptualizing high-level concepts to translating them into valuable and implementable digital products

  • Advanced skills in design tools such as Figma and Sketch

  • A track record of bringing concepts to life, turning UI designs into high quality full functional digital products or services.

  • Experience with DesignOps, e.g. managing and developing UI pattern libraries and style guides

Specific Knowledge/Skills:

  • Collaborative, user-centred mindset, with ability to co-create with stakeholders across business, product, and tech.

  • Experience facilitating workshops using Design Thinking methods to uncover user pain points and shape solutions.

  • A passion for data-driven decision-making and ability to root design decisions in a profound understanding of the user – experience with hands-on research is a plus

  • Familiarity with data-driven design: using usage analytics, feedback loops, and usability testing to improve flows and interfaces.

  • Excellent verbal, written, and visual communication skills in English (German a plus), with the ability to create high-impact presentations and explain design rationale to non-designers.
