UIontwerper

UIontwerper, or gebruikersinterfaceontwerper, is a professional who designs the visual aspects of user interfaces for digital products such as websites and mobile apps. The role concentrates on the look and feel of the interface, translating product requirements into visually organized layouts and interactive elements. A UIontwerper aims for consistency with brand guidelines and design systems while supporting usability and accessibility.

Key responsibilities include creating high-fidelity mockups and interactive prototypes, developing and maintaining style guides and design systems, and specifying UI components and their states. They define responsive behavior across devices, ensure accessibility considerations (contrast, keyboard navigation, WCAG guidelines), and collaborate with UX designers, product managers, and developers to implement the final interface.

Skills and tools commonly used involve proficiency with design and prototyping tools such as Figma, Sketch, and Adobe XD, as well as knowledge of typography, color theory, grid systems, and motion design. Familiarity with front-end constraints and design tokens helps ensure feasible handoffs to developers. Attention to detail, communication, and collaboration are essential, as is the ability to balance visual elegance with practical usability.

Education and career paths vary; many UIontwerpers hold degrees in graphic design, interaction design, or related fields, supplemented by a strong portfolio. Typical progression leads from junior UI designer to senior or lead designer, with potential roles in design systems, product design, or brand design. In Dutch-speaking contexts, the term UIontwerper or interfaceontwerper is commonly used, with employment in tech companies, digital agencies, and startups.
