UI Developer Job Descriptions, Average Salary, Interview Questions

What Does a UI Developer Do?

The user interface (UI) is where users control and use a particular piece of software, and UI developers are responsible for visualizing and creating that part of a program. A UI developer lives at the intersection of computer programming, psychology, and graphic design. UI developers have to get inside a user’s mind and predict how a user would want to control a piece of software, then design an interface that is intuitive and easy to learn.

UI developers are responsible for making sure programs behave as users would expect them to. They often have to have a wide variety of expertise, including knowledge of web development languages like HTML, CSS, and JavaScript, as well as application programming languages like Java, .Net, AJAX, and Ruby. UI developers should also have proficiency with graphic design programs like Adobe Photoshop, Illustrator, Flash, and Flex to design the look of the user interface.

In addition to hard technical skills, UI developers should also have soft skills like verbal and written communication, project management, team leadership, and presentation. A UI developer needs to be able to effectively communicate ideas to stakeholders outside of the development team to align the goals of a particular project. Generally, a UI developer doesn’t work alone, so team leadership and the ability to motivate and coordinate colleagues are also critical.
