Payment solution that simplifies the customer purchasing process.

Data Engineer
Stockholm, SE
Job Description / Skills Required

Engineers within Analytics enable Klarna to make real-time credit risk and fraud decisions using behavioural data.

Klarna’s mission is to take the friction out of how people buy online and we enable our users to purchase online using two bits of top of mind information - your email and postcode. When a user buys with Klarna we determine in real-time if the buyer really is who they appear to be, and if we are prepared to underwrite credit for this transaction and take on the risk. In summary our secret sauce is the ability to issue credit in real-time using behavioural data.

With 60M customers, 70k merchants and an annual purchase volume growth in excess of 50% this is a fintech business the deals with growth, scale and all the challenges that come with our ambition to grow the company by 5x in the next three years.

A few of the things that set us apart:

We work in small highly collaborative agile teams that typically includes Data Scientists, Software Engineers, Analysts and a Product Manager. You and your team will have a clear mission and ownership of an important outcome that supports Klarna and our customers.
