In my article “Who does what in UX? A detailed look at the roles and their contributions”, I presented the various tasks and responsibilities in the field of user experience. Today, I would like to delve deeper into the role of the UI designer. But what exactly does a UI designer do? Why is their role so important in product design? In this article, we’ll look at the job description of a UI designer, their tasks and the skills that are essential for this exciting profession.

The role of a UI designer

A user interface (UI) designer is responsible for the creation and design of user interfaces for digital products such as websites, apps and software. The main goal of a UI designer is to create a visually appealing and intuitive interface that allows users to interact pleasantly and efficiently.

While UX designers focus on the overall user experience, the UI designer’s focus is on the visual and interactive elements of the user interface. UI designers work closely with UX designers to ensure that the visual design supports functionality and usability.

The role of a UI designer typically includes the following tasks:

  • Developing layouts, colour palettes, typography and graphic elements
  • Creating wireframes and mockups that serve as blueprints for the final user interface
  • Collaborating with developers to ensure the design is implemented correctly
  • Conducting usability tests and gathering feedback to continuously improve the design

UI designers are critical to creating an engaging and user-friendly interface that fulfils the needs and expectations of users.

Important tasks of a UI designer

A UI designer takes on a variety of tasks, all of which are aimed at creating an appealing and functional user experience. Here are some of the most important tasks of a UI designer:


Designing user interfaces

UI designers are responsible for the visual design of user interfaces. This includes the selection of colour palettes, typography, icons and other visual elements that shape the overall appearance of the product. Their goal is to create an aesthetically pleasing and consistent design that reflects the brand identity and promotes usability.


Development of wireframes and mockups

An essential part of the work of a UI designer is the creation of wireframes and mockups. Wireframes serve as a rough framework that visualises the structure and arrangement of the various elements of the user interface. Mockups go one step further and add details such as colours, images and typography to give a more realistic picture of the final design.


Collaboration with developers

UI designers work closely with developers to ensure that the design is implemented correctly. This collaboration includes the creation of design specifications and style guides to help developers accurately understand and realise the design vision. Regular meetings and feedback sessions are crucial to ensure the design and development are in sync.


User-centred design approaches

Effective UI design is based on a deep understanding of user needs and behaviour. UI designers conduct usability tests, collect feedback from real users and use these insights to continuously improve the design. This iterative process helps to create a design that is not only aesthetically pleasing, but also functional and user-friendly.


Prototyping and interaction design

UI designers create interactive prototypes that allow the design to be seen and tested in action. These prototypes simulate user interactions and help to identify problems at an early stage and optimise the interaction design. This is particularly important to ensure that the final product can be operated smoothly and intuitively.


Maintaining and updating the design

A UI designer’s work does not end after the launch of a product. They are also responsible for the ongoing maintenance and updating of the design to ensure it meets current trends and user requirements. This may include introducing new features, customising the design based on user feedback or updating the visual style.

Important skills and qualifications

A successful UI designer needs a mix of creative, technical and social skills. Here are the most important skills and qualifications a UI designer should have:


Creative skills

  • Aesthetic understanding: A good eye for design is essential. UI designers must be able to create appealing and harmonious designs that reflect the brand identity.
  • Creativity and ability to innovate: The ability to find creative solutions to design problems and develop innovative ideas is of great importance.


Technical skills

  • Design software skills: UI designers should be familiar with common design tools such as Sketch, Figma, Adobe XD and Photoshop. These tools are essential for creating wireframes, mockups and prototypes.
  • Basic programming skills: Knowledge of HTML, CSS and JavaScript is advantageous as it improves understanding of the technical realisation of designs and facilitates collaboration with developers.


Understanding of interaction design and user guidance

  • Usability and user experience: A deep understanding of usability principles and user experience is crucial. UI designers need to know how users interact with an interface and how they can improve the user experience.
  • Prototyping and testing: The ability to create interactive prototypes and conduct usability tests helps to validate and optimise the design.


Soft skills

  • Communication skills: UI designers must be able to communicate their design ideas clearly and effectively, both within the team and with stakeholders
  • Teamwork: Collaboration with other designers, developers and project managers requires strong teamwork skills.
  • Time management and organisation: As UI designers often work on several projects at the same time, good time management and organisational skills are essential.


How to become a UI designer

Becoming a UI designer requires a combination of formal education, hands-on experience and ongoing training. Here are the steps typically required to become a UI designer:

Education and training opportunities

  • Design degree: Many UI designers have a bachelor’s degree in graphic design, communication design, interaction design or a related field. These degree programmes teach basic design principles as well as technical skills.
  • Courses and bootcamps: Specialised courses and bootcamps in UI/UX design can be a good alternative or supplement to a traditional degree. They offer practice-orientated training and are often shorter and more intensive.
  • Cross-entry: It is also possible to become a UI designer as a career changer. Many successful UI designers come from related fields such as graphic design, web development or even marketing. They can acquire the necessary skills through self-study, online courses and practical experience.


Important experience and internships

  • Practical experience: Internships, freelance projects or personal design projects are crucial for gaining real-world experience. They offer the opportunity to put what you have learnt into practice and get a feel for working as a UI designer.
  • Portfolio building: A strong portfolio is often the most important tool for a UI designer. It should contain a selection of projects that demonstrate your skills and understanding of design. Each project should document the design process from research to realisation and the result achieved.
  • Usability testing and feedback: Experience in conducting usability tests and obtaining user feedback is important. These skills help to continuously improve the design and adapt it to the needs of users.


Network and community

  • Networking: Building a network in the design industry can open doors. This can be done by participating in design conferences, meetups or by joining design communities and forums.
  • Community: Participating in online communities and forums can also be valuable. Platforms such as Dribbble, Behance and design subreddits offer opportunities for exchange and inspiration.
  • Mentorship: A mentor from the industry can provide valuable insight and advice as well as support with career development. Mentors can often be found through networks, community events or online platforms.


Through a combination of formal education, practical experience and a strong network, you can successfully build a career as a UI designer.


UI designers play a key role in designing user interfaces that are both appealing and user-friendly. The path into this profession can be varied, from traditional degree programmes to lateral entries. However, creative, technical and social skills as well as continuous learning are essential. A strong network and practical experience also contribute to success. The future in UI design offers numerous opportunities and exciting challenges.
