Senior frontend engineer

What you will do

You work on the library: the screen where half a million files must scroll smoothly, where multi-select has to behave the way it does in a file manager, and where every frequent action belongs on the keyboard.

This is not work where "it works" is enough. A tile that appears 40 milliseconds late goes unnoticed in a demo and becomes unbearable after an hour of use.

What we are looking for

• React and TypeScript at a level where types help you rather than fight you.
• A feel for performance: you know why something stutters, not just that it does.
• Accessibility as a design question, not a checklist afterwards.
• You write Dutch or English; the team does both.

What we will not ask

No weekend-long take-home assignment. We look at real code together — ours, and yours if you want to show something.
