A user interface (UI) developer assumes a technology-centered role that aims to combine programming, human psychology, and creative design to create a digital software that provides smooth and relevant user experience (UX)

He or she is tasked to develop an interface that matches user expectations. For example, a UI developer can make web page navigation simple, user-friendly, and straightforward. The task is more than using the right fonts and colors. UI developers have to make sure that the design they create is relevant to end-users. A UI developer can also choose to specialize in specific platforms, such as mobile or web.

What Skills and Qualifications Should UI Developers Have?


UI developers should have at least a bachelor’s degree in computer science, mobile computing, web development, software engineering, or any related field. While getting certifications from reputable organizations can help, they don’t increase your chances of getting hired. Often, hiring managers would consider a UI developer’s portfolio instead.


UI developers should demonstrate knowledge of frontend web development, human-computer interactions, mobile development, interactive media design, and usability testing. They should also possess programming skills in JavaScript, HTML, CSS, JavaScript Object Notation (JSON), AJAX, Java, jQuery, Ruby on Rails (ROR), and SQL database development.

How Much do UI Developers Earn on Average?

A UI developer’s salary depends on his or her experience. According to PayScale, a U.S.-based UI developer can receive at least US$61,000 annually. Those with extensive experience, spanning more than 20 years, can expect to get at least US$112,000 a year. However, the salary would depend on the UI developer’s location. Compensations are often higher in urban areas, particularly in those with a high concentration of tech-focused organizations.

With the booming e-commerce industry, UI developers can expect to enjoy an even much higher demand for their skills and expertise.
