Technical Skills to Check Before Hiring Frontend Developers

The future of frontend development is constantly changing. The increasing number of frameworks, languages and open-source projects means frontend developers’ skills continuously evolve. Recent research has concluded that frontend development is one of the fastest growing job categories in the US as more companies move their applications to the cloud.

We believe 80% of success is showing up. If a person is qualified enough, they will have no problem getting a job. However, there are some things you can do before you hire frontend developers to make your life easier.

Top 10 technical skills to check before hiring frontend developers

The quality of the frontend development directly impacts the user experience. Therefore, hiring a frontend developer with the right skills is vital to building a great website. The front end is one of the essential parts of any website. A website with a beautiful design and easy navigation is the first thing visitors see.


Hiring a frontend developer can be a daunting task. There are many factors to consider, and the wrong decision could cost your business a lot of money and time. Here are some top 10 technical skills to check before hiring frontend developers: 

1. Knowledge of HTML5 / CSS3 / JavaScript

HTML5, CSS3 and JavaScript are essential for creating any web application or website. These technologies have been used widely in creating complex websites like Facebook, Google Maps and Gmail. They continue to be used by developers to build new features in existing applications.

This is the most important skill to look for. The web is built on HTML and CSS, and JavaScript is used to add interactivity. Frontend developers should know how to code in these languages.

2. Responsive design

Responsive design is designing a website to respond to the size of the screen it is viewed on. It means that your website will look good and function well on any device — whether it’s a desktop computer, tablet or mobile phone — regardless of screen size. With the total number of smartphone users on the rise globally, the need for responsive design is also in demand.

It has become increasingly important as more people access the internet via mobile devices. Responsive design ensures that your website looks its best no matter what kind of device someone uses to view it.


3. Understanding of agile methodologies

This is one of the most critical skills that a frontend developer needs to possess as they will work closely with other team members who follow Agile methodologies such as SCRUM or Kanban boards to manage their workload effectively and efficiently over time to deliver quality products within deadlines set by management teams or clients alike.

When hiring frontend developers, they must understand how agile methodologies work to contribute effectively towards making their projects successful while working closely with other team members such as the back-end. 52.9% of developers accept that they use SCRUM methodology as per research done with 19 frontend experts from 125 countries.

4. CSS preprocessors

The frontend developer should be proficient in CSS preprocessors. CSS preprocessors are tools that extend the features of CSS by allowing you to write code in other languages. They can help you manage your CSS code better, use variables and functions and do many other things that might be too much for pure CSS.

For example, if you have a page with multiple buttons, you can create a mixin that will be applied to each button and save time by not having to write the same code repeatedly.

5. Version control

Version control is a must-have tool for any developer, and the frontend is no exception. If you’re unfamiliar with version control, it’s the process of managing changes to code over time. Changes are stored in a repository, and when a developer wants to change code, they make that change in their local copy (the “working copy”). Once the change is made, it’s committed and pushed to the repository for others to see.

The benefit of version control is that it provides an audit trail of who did what and when. It also makes it easy to roll back if something goes wrong — another reason why it’s essential for frontend developers!

6. Web performance

A good frontend developer should know how to create websites that perform well across all devices. This includes optimizing images for the web, creating forms that work well on mobile and desktop devices, and ensuring that the code is easy to read and understand.

Web performance is a crucial factor that can affect the speed of your website. Having fast-loading web pages is essential, especially if you want to keep visitors engaged and coming back.

7. Browser developer tools

The browser developer tools are essential for frontend developers. These tools allow them to inspect elements on a page and see how browsers display them.


This is crucial because different browsers will often render elements differently, and using these tools allows developers to ensure their websites look consistent across all platforms. These tools help you understand how a website works and what code is being used by it. If a developer is not familiar with these tools, they will be unable to build websites effectively. 

8. Proficiency in MVC frameworks

MVC stands for Model-View-Controller, a way of organizing code that makes it easier to understand and write complex applications. If you’re unfamiliar with MVC frameworks, it may seem like a strange concept — but they’re pretty standard in the world of frontend development.

A good frontend developer should know how to use the most popular MVC frameworks, such as AngularJS and Backbone.js. This will allow them to work on projects that require more complex functionality without getting overwhelmed.

9. Expertise in platform and device compatibility 

The front end is the first experience a user has with your website, so it must be built in a way that they can easily interact with it. The best frontend developers have extensive knowledge of web development platforms, including HTML5 and CSS3 and cross-browser compatibility. 

Frontend developers should understand how browser compatibility works, including how browsers render HTML and CSS and how those technologies interact with each other.

10. Experience in Bootstrap/Semantic UI/Material Design

Frontend developers should be familiar with these frameworks. Bootstrap is an open-source frontend framework for designing responsive websites. It provides all the essential elements required to develop a website, such as buttons, tables, forms, tabs and others.


Semantic UI is a user interface kit for developing applications on any device. It offers predefined components that can be used to create websites and applications quickly without writing code from scratch. Material Design is a language developed by Google that uses bold colours, shadows and animations to make applications more interactive and intuitive for users.

Wrapping Up

 Always do a little research and preparation before reaching out to designers or frontend developers. The key to making the right decisions is knowing what to look for, and finding the best candidates is knowing how to find them.
