Klarna Checkout is our flagship product. It is a single page, Javascript app which sits in an iframe in several of the biggest web shops in Europe.

You will be a part of a world class team that cares deeply about what it does. It’s as much focus on building a kickass product as it is on crafting clean code. The challenge is to build a highly configurable client that scales with a rapid international expansion. We want to be the world’s favorite way to buy.

As a developer you will work across the entire client, from usability and design to writing high performance code. You will work closely with your colleagues to solve complex problems, from analyzing the problem to designing, planning and implementing new functionality.

Skills & Requirements

So who are you? You consider yourself a full stack or front-end developer that is passionate about coding and deeply care about the user.
