This challenge is part of the hiring process for some positions at MUI. The idea is to make as much progress as possible under a given time constraint of (3-4 hours).
MUI is a fully remote company with a team that spans the globe. The majority of our work is asynchronous, and we rely on written communication to collaborate. We're radically transparent: nearly all of our work happens in public.
For additional details about the culture, you can check our careers and about pages and also our public Handbook.
MUI is best known for our flagship product, Material UI—but this is just one of three core component libraries we maintain. Base UI is our headless component library, and Joy UI is a sister library to Material UI that implements our own in-house Joy Design system. We also host Design Kits and pre-built Templates.
Beyond the core libraries, MUI X offers advanced components like the Data Grid, Date and Time Pickers, and Charts, for more complex user interactions and data visualization needs.
We're also making ambitious moves to incorporate our full suite of components into Toolpad, a low-code admin builder tool for assembling full-stack apps faster than ever.

Given that the Design Engineer position sits right at the intersection between engineering and design, this challenge aims to simulate how a potential day-to-day situation plays out. Our challenge is to develop a stacked Snackbar component. We'll review how you make design decisions and the quality of the written code.
Here's an example design:
We encourage you to add your creative spin to the design—we want to see your design taste!
- Stack: Use the Base UI Snackbar or a similar headless component from a library of your choice as the foundation.
- Transitions: the Snackbars should appear and disappear gracefully on the screen, using an animation.
- Dark mode: make sure to support light and dark modes.
- Interactivity:
- The other Snackbar instances should be visible after some interaction, either clicking a button or hovering over the stack.
- They should stay open when focused, and collapse when the focus moves away.
- Each instance should have a functional close button.
- Bonus: Add an option to make the Snackbars close automatically after some configurable time interval. This should be compatible with WCAG 2.2.1.
To save you time, we created a working environment with Next.js, TypeScript, ESLint, and other complementary dependencies. Follow the steps:
- Clone the repo:
git clone [email protected]:mui/tech-challenge-design-engineer.git - Install the dependencies:
pnpm i - Start Next.js:
pnpm dev - Open http://0.0.0.0:3002/
Instructions:
- DO NOT fork / host your project on a public repository.
- Please send us a zip file containing this project using the upload link that we have provided by email (with the .git folder).
- To significantly reduce the size of the archive, remove the
/_node_modules_/and/.next/folders. - If you don't have the upload link, you can send it to [email protected].
We're excited and looking forward to seeing what you'll create! Good luck 🚀
