An overview of a UI developer role

User interface (UI) development has become essential to software development. Customers could stop using your software product if it gets confusing or time-consuming on their part, making you lose your base in return.

The role of a UI developer is crucial in ensuring that a software application has an appealing and user-friendly interface.

Let’s look at what a UI developer does, the skills required for the role, and how outsourcing UI development can benefit companies.

What is a UI developer?

A UI developer is in charge of designing the user interface of a software application. They ensure the program is visually appealing, easy to use, and offers a consistent user experience.

UI developers collaborate with designers, developers, and project managers to ensure the program satisfies the client’s needs.

A UX designer is responsible for researching, testing, and developing the overall user experience. They focus on the application’s general layout, structure, and flow.

Meanwhile, a UI developer works on the visual design. They use distinct design aspects in an app’s interface that complement each other well, such as colors, font, and layout.

Responsibilities of a UI developer

A UI developer’s primary responsibility is to ensure a system’s user interface is visually appealing and easy to use. 

They work closely with designers to translate their designs into functional user interfaces, ensuring everything is implemented accurately.

Along with other developers, they help integrate the user interface with the back-end functionality of the application.

Other responsibilities of a UI developer include the following:

  • Maintaining a style guide for the application
  • Ensuring its responsiveness and compatibility with various devices and platforms
  • Optimizing the user interface for performance and accessibility
  • Conducting user testing and gathering feedback for continuous improvement

Tools used by UI developers

UI developers use various tools to create and design user interfaces. Some of the most common tools include:


Figma is a collaborative design tool used to create product mockups, prototypes, and testing. It works the same way as Google Workspace, where everyone can collaborate with different users in real-time.


Sketch is a popular UI design tool that designers mostly use. More than drawing designs, the platform is mostly used for wireframing and prototyping through its vector-based system.


Compared to Sketch, InVision is a next-level prototyping tool used by both UI and UX developers alike. The platform allows users to upload static designs and create interactive prototypes out of them.


As an open-source vision control system, Git is designed to help teams collaborate with their projects quickly and efficiently. It is used by both starting and established companies such as Netflix, Microsoft, and LinkedIn.

Visual Studio Code

Lasty, Visual Studio Code is a free code writer, and editor developers use. It supports multiple programming languages, such as Python, C++, and JavaScript.

How an outsourced UI developer benefits companies

Outsourcing UI development has become a popular trend in recent years, and for good reason. Companies outsourcing their UI development needs to a specialized team can benefit in several ways.

  • Faster product release and delivery. Outsourced UI developers possess extensive experience and expertise in UI design and development. This allows them to execute tasks efficiently and release new products or features quicker.
  • Up-to-date industry trends. With their industry-wide experience, outsourced developers can provide valuable insights into industry best practices, emerging trends, and preferences they can use with certain projects.
  • Diverse skill sets and expertise. Outsourced UI developers bring a diverse skill set acquired through their exposure to various clients. This allows them to approach your project from different angles and incorporate innovative ideas across specific industries.
  • Quality assurance. A reputable outsourced UI developer often maintains stringent quality assurance processes and comprehensive testing methods, ensuring the quality of each software product they create.
  • Focus on core competencies. Organizations can redirect their internal resources toward activities that align directly with their primary business goals by delegating UI development. 

With the benefits of outsourcing becoming increasingly evident, companies should consider this option when developing an application’s user interface.
