In the beginning, there was only köp&sälj. At the time in ancient tech history, some 25 years ago, this diamond was born. Not to brag, but it was a success from the start. A masterpiece that has been cloned and exported to +30 countries. A famous and very loved product by people all over the world. And by nature. Oh dear, what good it brings to Mother Earth. Today, this part of Blocket is still the core of everything. No köp&sälj, no Blocket.

The greenest part of our red heart now needs its new Back End focused Full Stack Developer. And even if we have been around for a while, there are as many exciting things ahead of us in this marketplace jewel. Just as it was in the beginning.

We are Blocket, Sweden’s largest and most popular marketplace with around 12,3M monthly active users generating 100 million sessions. We are proud of our work to enable second-hand trade in Sweden and our contribution to a positive environmental impact.
