This is an engineering position, not a data science one with some engineering on the side.

You'll work alongside a team split between Stockholm and Warsaw, and help scale Klarna's in-house data science capability as the credit risk and fraud teams grow.

What you'll do You'll write Python to train credit underwriting models, including tree-based models, and prepare them to run in production.
