• Actively participate in and contribute to multiple cross-functional product squads, collaborating closely with Product Managers, Engineers, and fellow Designers to ensure seamless integration of design into the development process.

• Champion the growth and maintenance of SumUp's design system, ensuring its scalability, consistency, and adoption across new and existing product features to optimize design efficiency.

• Integrate qualitative user research findings and quantitative user data into the design process to iteratively improve product usability, effectiveness, and merchant satisfaction.

• Translate complex business requirements and user needs into intuitive and elegant design solutions that drive merchant success and platform adoption.

• Proactively identify opportunities for design innovation and process improvement within the Sell Online team and the broader product organization.

This suggests a significant level of autonomy and responsibility, typical for a Senior Product Designer. The emphasis on "crafting visually compelling interfaces" and "contributing to and evolving our design system" implies a need for both strong individual contribution and strategic thinking about design scalability. The need to "use qualitative research and user data to inform design decisions" points to a data-informed design methodology.
