A guide to hiring an animation developer
Animation is movement with a purpose. On a website it can show where a menu came from, confirm that a button was pressed or draw the eye to a price. In an app it can make a screen feel quick and clear. In a game it brings characters and objects to life. An animation developer is the engineer who builds this motion so that it works in the real product. Here is what the role includes, how it differs from nearby jobs and how to work well with a remote engineer. It is most useful for founders and product managers who have designs with motion in them and need someone to make them run well.
Two main kinds of animation work
The first kind is interface and web animation. It covers transitions between screens, scroll effects, animated icons, loaders, charts and product tours. The tools are CSS, JavaScript and often a library for timing and sequences. The second kind is real-time 3D animation. It covers character movement, objects that react to touch and scenes that run in a game engine or in the browser. The tools are engines such as Unity and Unreal Engine, or web libraries such as Three.js. Some developers do both, but many are stronger in one, so say which kind you need.
What an animation developer is responsible for
The job is to turn a plan into working motion. An animation developer reads the design and any motion notes, builds the effect, tests it on real devices and tunes it until it is smooth. They add a way to turn motion down for people who prefer it, and they keep the page or app light enough to load quickly. They also write the code so that other developers can find and change the timing later.
How an animation developer differs from other roles
A motion designer or an animator creates the movement itself, often in a design or 3D tool. Our graphic designers can include motion work. A web developer builds whole sites and may add light effects. A JavaScript developer goes deeper into the code behind interactive pages. A UI/UX designer plans how the product should feel. For games, a game developer builds the systems and a Unity developer knows that engine in depth. Use the animation page when the main problem is motion that must run well in code.
When an animation developer makes sense
- Your designer has made motion that your current developers cannot build well.
- Your site has effects that stutter, drain batteries or slow the page down.
- You want a product tour, an animated explainer or an interactive 3D product viewer.
- Your game characters need smoother, more responsive movement.
- You want a single expert to set motion rules for the whole interface.
If you need a video or hand-drawn animation, a motion designer is the better start. If you need whole new screens and features, a front-end or full stack developer will cover more.
Reading an animation developer’s background
Open the live work and use it. Scroll slowly and quickly, resize the window, try it on a phone and turn on a reduced motion setting. Good work still feels clear when you do all of that. Be careful with a portfolio made only of screen recordings. A recording can hide dropped frames, long load times and effects that break when the device or the browser changes.
Interview questions to try
- An animation looks fine on your computer but jerky on a phone. What do you check?
- When would you use CSS only, and when would you add a library?
- How do you handle the setting for reduced motion?
- How do you work with a designer who sends you a motion file?
- What would you do if a 3D model is too heavy for a web page?
Listen for a clear order of steps and for examples from real projects. Doubt anyone who talks only about how an effect looks and never about how it runs.
Try a paid mini project
Give each finalist a small task from your own product. Useful examples are one animated component built from your design, a review of your slowest animated page with a list of fixes, or a short plan for adding motion to a key user path. Pay for the time. Look at the care in the details, the speed on a weak device and the way the person explains choices to a non-technical colleague.
Match the person to your product
A marketing site with scroll stories needs someone who loves web motion and page speed. A software product needs someone who cares about small, useful feedback in the interface. A game or a 3D viewer needs an engineer who is at home in an engine and can work with artists. Job titles vary, so ask which parts of past projects each candidate built themselves.
Agree access and routine
Set the weekly hours at the start and review them every quarter. Give your developer their own logins to the code, the design files and the staging site, and keep ownership of every account in your company name. Ask for a short demo at the end of each task, and a written note about any setting or file that was changed. Remove access when the work ends.
Working with your team
Put the designer and the developer in touch from day one. Share your brand rules about speed, tone and style of motion so the first version is close. A short weekly call and a shared list of tasks keep everyone aligned. Ask for a small guide that lists the timings and curves in use, so any future change stays consistent.
Mistakes to avoid
- Adding motion to everything, so nothing stands out.
- Testing only on a fast computer.
- Ignoring users who need less movement.
- Giving a contractor the only login to your code or design accounts.
