UI Engineer II

Your opportunity

At Mollie, our mission is to make payments and money management effortless for every business in Europe and the UK. With that mission, the App Core team focuses on enabling product teams to ship customer-facing features faster, across web and mobile, with a great developer experience.

We’re looking for a UI Engineer who’s excited about platform work : improving how features are built, released, and maintained across multiple apps and teams. Rather than owning a single end-user feature, you’ll help create the foundations that allow other teams to move quickly and confidently — from smoother release cycles to better tooling, infrastructure, and localisation workflows.

You’ll work on systems that sit at the heart of our development process, shaping how engineers build, test, release, and scale Mollie’s products. Your work will directly impact hundreds of engineers and, through them, hundreds of thousands of customers.
