Data Warehouse Developer

Klarna makes shopping smoooth. And we do it with flair because shopping is fun. Every day, we help customers, businesses, and partners explore just how smoooth the modern shopping experience can be. 

It means we’re constantly changing the game. Always trying out new things. And we encourage our people to do the same. To grow. To develop. Because we don’t believe roles have to stay fixed. Instead we inspire our people to take an irregular career path. As a company of 350 dynamic start-ups, our whole business is built for it. So once you’re in, there’s no telling what will happen next.

What you will do

We offer the rare opportunity to curate the whole data journey in a big fintech company. You will work in the Data Domain and enable Klarna to understand, predict and make the right decisions based on large, fast, structured, unstructured and growing amounts of data. The data journey starts in the data producing systems, then travels through the Data Lake, is refined in the Data Warehouse and presented to both internal and external users in the BI Applications. You love solving complex problems, challenging the batch models written, optimizing data models and writing SQL queries. You encourage a social environment at work and share energy and inspiration to your teammates.

Your stakeholders will be Data Scientists, Business Analysts, other Engineers and all Klarna employees that need data in their daily work. We have amazing teams that take care of and become experts at different parts of the domain where sharing and collaboration are key.

Some of the technologies and languages we use are AWS Glue (Spark), AWS Redshift, Apache Airflow, and Qlik Sense. We try to be SQL and code focused; and we are always looking for the most efficient tool for the job.

You should have

  • Relevant education with a degree in engineering or comparable skills
  • Experience as a Data Warehouse developer or comparable position
  • Experience working with SQL, databases and BI tools. We really like SQL!
  • Working proficiency and communication skills in verbal and written English
  • A burning curiosity and interest in data, fast data, big data, dark data, data governance, data models, data warehouse, data insights - or all of the above!
