A guide to hiring a front-end developer
The front end is everything a visitor sees and uses in a browser: the layout, the buttons, the forms, the menus and the small movements between them. A front-end developer builds it with HTML for structure, CSS for style and JavaScript for behaviour. Many also use TypeScript and a framework such as React, Vue or Angular. If you want a clean interface, a faster site or a team member who can take designs all the way to working pages, this is the role to look at.
What a front-end developer actually owns
The job is wider than it looks from the outside. A front-end developer takes a design and builds each screen from reusable parts. They make it work on a phone, a tablet and a large monitor. They connect it to data from your back end and show sensible messages while data loads or when something fails. They keep it usable with a keyboard, and they keep it fast. When your product grows, they keep the code readable so the next change is not scary.
Responsive and accessible by default
Many people will meet your product on a small screen, so layouts must bend without breaking. Accessibility matters for the same reason. The W3C publishes the Web Content Accessibility Guidelines, known as WCAG, which explain how to make pages usable for people with different needs. A developer who builds with proper elements, clear labels and a logical focus order gets most of the way without extra work. A developer who adds these at the end finds them far harder.
Page speed and Core Web Vitals
Google’s Core Web Vitals are a set of measures for the experience of a page: how quickly the main content appears, how fast the page reacts when someone taps or clicks, and how much the layout jumps while it loads. Front-end choices drive all three. Large images, too many scripts and late-loading fonts are common causes of a slow page. A good developer checks real results, not only a lab test, and fixes the biggest cause first.
From Figma to a working page
Many teams design in Figma, a tool for drawing screens and sharing them with developers. The handoff is where problems start. A front-end developer reads the file, picks out the colours, type sizes and spacing that repeat, and turns them into shared styles. They also ask about the cases a design leaves out, such as a very long name, an empty list or a failed payment. Agree early who answers those questions, since small gaps turn into delays.
How a front-end developer differs from other roles
A web developer covers a wider field and may work on servers, a CMS and hosting. A JavaScript developer is strong in the language, both in the browser and on the server. A full stack developer builds the interface and the back end. A front-end developer goes deepest on the browser side: structure, style, behaviour, access and speed. Choose that depth when the interface is a big part of your product.
Pick the right framework, or none
Frameworks help teams build large interfaces from reusable parts, and the choice is mostly about your team and your product. React is common for apps with many moving parts. Angular suits large, structured business tools. Vue is often used for lighter interfaces and step by step upgrades. Svelte takes a different route and does more of its work when the code is built. Some pages need no framework at all. A good developer will say so when plain HTML and CSS are enough.
The jobs people hire for
The first job is a new interface for a product, built from a design. The second is a rescue: a site that is slow, breaks on phones or has grown into a pile of scripts. The third is a move to a newer setup, such as from older jQuery code to a component framework, one section at a time. The fourth is a design system, a shared set of components and styles that keeps many screens consistent.
When a front-end developer makes sense
- Your product has a lot of screens, forms or dashboards, and the interface is a big part of its value.
- Designs exist or are on the way, and you need someone to build them carefully.
- Your site is slow on phones and you want the cause found and fixed.
- You need accessibility improved without a full rebuild.
- Your back end team is busy and screens are waiting for someone to build them.
If you only need a small change to a content site, a web developer or a page builder may be a better fit. A developer who says so early is saving you money.
Reading a front-end developer’s background
Ask for a live interface they built and still know well. Open it on a phone, use the keyboard to move through it and watch how it loads. Good answers cover how the components were split, how the layout adapts, how accessibility was handled and what they would change now. Be careful with a background that lists tools and nothing else. Anyone can name a framework. What counts is how the product felt to use a year later.
Interview questions to try
- How do you decide when to split a screen into smaller components?
- How would you make this form usable with only a keyboard?
- What would you check first if a page felt slow on a phone?
- How do you work with a designer when a file leaves something unclear?
- When would you advise us not to use a framework?
Strong replies include reasons and a real example. Take care with anyone who treats a framework as a list of commands and cannot explain what the browser is doing underneath.
Run a small paid exercise
Set the same short job for each finalist, taken from your real backlog. Options include building one screen from a design, fixing the accessibility of an existing form or finding why a page is slow and proposing fixes. Pay for their time. Compare the code, the way they handle small screens, the questions they ask and how clearly they report back.
Agree how the code is kept healthy
Agree how branches, reviews and releases work, and who approves a change. Ask for a short note on shared components that says what each one does and how to use it. Keep the repository, the hosting account and the keys in your own name, with a separate login for each developer. That way the work belongs to you, whoever is on the team next year.
Settling in
Walk your developer through the main flows of the product and the screens people complain about. A weekly check-in and one shared board of tasks keep the work visible. Share the awkward cases early, such as a slow dashboard or a page that breaks in one browser, since those are the problems a good front-end developer is hired to solve.
Mistakes to avoid
- Judging a candidate by screenshots alone and not testing the live page.
- Leaving accessibility until the end of a project.
- Choosing a framework because it is popular and not because it fits the product.
- Skipping tests because the screens look right today.
