What Does a Front-end Software Engineer Do?

A front-end software engineer, also known as a front-end web developer or designer, works on the selection, installation, and testing of the user interface elements of a particular website. These engineers concentrate on how the site looks and feels and its functionality. 

The job prospects for front-end software engineers are pretty great, especially for those who possess the required skills that help them develop websites that can be accessed easily by mobile devices.

Programming Languages and Tools Used by Front-end Software Engineers

The most common programming languages and tools used by front-end software engineers are:

Programming Languages

Most front-end software engineers spend a lot of time using programming languages such as HTML, CSS, and JavaScript. Their proficiency in these languages determines how good they are at their jobs. 

HTML is used to layout the general structure and content, CSS is used for styling, and JavaScript is used in cases where advanced interactivity is required. Further, they might even use AJAX (JavaScript and XML combined) when updating specific areas of a website without having to refresh the whole page. 

Other programming languages they might need to use include Python, Ruby, or PHP. These are used to simplify connecting the data with the back end of their website.


As a front-end software engineer, you’ll be using a combination of design and web development in your work. Therefore, the tools have been divided into two categories:

  1. Graphic Design Tools

Before writing the code, front-end developers use graphic design tools to build a prototype. This lets them experiment and run tests with the user interface before they start working on the actual code.

The scope of the project determines which tools will be used. It might require something as simple as a pencil and paper or graphics editing programs like Sketch or Photoshop. Prototyping tools such as Balsamiq Mockups or more advanced graphical editing tools such as Figma or Illustrator might also be used.

  1. Code Editing Tools

Front-end software engineers use code editing tools to write code for the website. Some developers even choose to use lightweight editors such as Notepad, while others go for more advanced editors with more features like Visual Studio or Eclipse. 

Remember to test out a few different editors before you choose one to see which one will work best. 

Therefore, to get the best front-end software engineer jobs, you’ll need to grasp these programming languages and tools. You can also look at 7 Important Skills to Become a Successful Front-end Engineer.
