Klarna is growing. Very fast. Do you want to join us on this journey?

Klarna Checkout is our flagship product. It is a single-page Javascript app that sits in an iframe in over 50,000 webshops across the world. And that number is growing by the day.

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 and well-tested code. The challenge is to build a highly configurable client that scales along with our 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.

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. You love building cool products and have a blast with your colleagues while doing it. And you probably take part in the front-end/Javascript community and spend several hours a week trying out new stuff.
