Hadoop expert

The newly opened Uppsala office works with engineering projects related to the core infrastructure to ensure that Klarna stays ahead of the fierce competition. Our main system is written in Erlang but the Uppsala team will mainly build new components based in other technologies. Currently we are looking over the data flows, storage and analysis to improve the way Klarna can utilize the large amounts of data collected throughout the organization. Other topics include distributed data replication, streaming database analysis and the impact of how different ways of choosing what to sacrifice in the CAP theorem influence different parts of our platform.

We are looking for a Hadoop expert for our Backoffice core team to grow, improve, and support our Big Data infrastructure. We provide this infrastructure to the product, risk, finance, and engineering teams within Klarna. In particular, we use our infrastructure to improve the risk assessments in real time.

Klarna wants to leverage its data to improve its products and growth, to minimize risk, and to identify opportunities ? to make online shopping even simpler, safer, and more fun.

- B.S., M.S., or PhD Computer Science or related field
