The Merchant Experience domain’s mission is to craft seamless experiences so every Mollie moment feels intuitive, secure, and supportive. The vision is simple: customers stay focused on growing their business while Mollie just works. We are hiring UI Engineers across the domain.
We care deeply about quality and well-designed experiences, not only for our customers, but especially for the engineers building Mollie’s products. This means creating clean, well-documented APIs, reliable tooling and smooth workflows that make development, testing, localisation, and releases easier and more predictable. It also means owning the design system and navigation experience that merchants interact with every day, driving engagement, accessibility, and product activation at scale. As a UI Engineer, you bridge the gap between platform capabilities and the teams that rely on them, working across the frontend, backend and infrastructure as needed.
This is not a role where you ship one feature and move on. You will have real ownership, real visibility, and the chance to do work that matters at scale.
