About Klarna

We're creating the world's smoothest shopping experience. We serve almost 100 million consumers worldwide, and partner with 250,000 merchants – with a new merchant joining us every 8 minutes. Including some of the world's leading brands, such as H&M, ASOS, IKEA, Adidas, Samsung and Lufthansa. Our offices are spread over 24 different markets, hosted by 5000+ employees from 100+ nationalities.

We work in small, highly collaborative Agile teams. You and your team will have a clear mission and ownership of an important outcome that supports Klarna and our customers. At Klarna we optimise for quality, flow, fast feedback, focussing on end-to-end ownership, continuous improvement, testing, monitoring and experimentation. We aim for teams that are inclusive, helpful, and have a strong sense of ownership for the things they build.

What you’ll get to do

• Own your services end to end. Decide how best to build, test, deploy and monitor.
• Work with large scale, highly available and resilient modern financial systems.
• Be an integral part of a team, in addition to its culture and ways of working. Common practices include agile methodologies, pair and mob programming.
• Work with automated deployment enabling code release multiple times a day.
• Succeed, fail, and learn together with other talented people. We believe in an environment that provides an opportunity for growth and see education as an outcome of failure that gets us closer to the next breakthrough.
• Work with modern tools and languages that excite you.

You'll get the chance to work with

• Functional programming languages including Erlang, Clojure, Haskell, Functional Typescript and JVM tooling.*
• We are also utilising:
• Mnesia, and a range of OTP tools.
• Kafka, Serverless, PostgreSQL, DynamoDB, LevelDB.
