We currently serve 60 million consumers, work together with 130,000 merchants and process more than a million payment transactions a day. We are growing at 40% year on year and our investors include Visa, Atomico, Sequoia Capital, Permira and Bestseller group/ Anders Holsch Povlsen. We have strong partnerships with some of the world’s leading brands, such as ASOS, IKEA, Adidas, Zara, Lufthansa and Spotify. 

To find out more about what it's like to work at Klarna:


Klarna is the largest fintech company in Europe to become a bank  and we aim high. We don’t focus on where we’ve come from. What matters  to us is where we are going. Klarna’s goal is to improve the online  buying experience for our consumers and merchants all over the world.

Security lies at the core of all the things we do at Klarna and we're looking for people passionate about taking our security operations in a highly dynamic environment to the next level. In the Vulnerability Management team, we're assessing the security of everything that is built and run in Klarna’s IT environments through both manual and automated assessments. We see an ever growing need to ensure the solutions we build are secure, and are therefore now looking for security engineers with solid experience of identifying and remediating vulnerabilities in today’s common technologies as well as the ability and passion to quickly take on tomorrow’s technologies.

As a security engineer within the Vulnerability Management team, you’ll be sharing your time between performing security assessments of the solutions Klarna teams are creating and building tools and mechanisms for giving us a continuous real-time view of identified security issues. We constantly challenge our ways of working to make sure we're keeping up with Klarna's fast-paced development progress. In order to achieve that, we're focusing heavily on automating everything that can be automated so we can spend more time on security assessments and coming up with solutions to new problems.

If you feel at home when breaking solutions using the latest technologies in cloud environments and are passionate about creating solutions that scale security assessment processes through automation, this is a position for you. You will get a lot of opportunities to shape how we best secure our environments on all levels of our tech stack today and in the future - networks, systems,  containers, orchestration layers, CI/CD pipelines, and more. We provide a mentoring and  competence track specific for you to get you up to speed.

Get in touch with us if you would enjoy...

  • Assessing the security of our tech stack through whatever means are best suited
  • Building tools to handle everything that’s better suited for automating than doing manually
  • Working with engineering teams to drive security improvements
  • Taking an active role in architectural decisions
  • Having fun and sharing your knowledge and expertise while doing so

It would be great if you have some of the following...

  • Experience within penetration testing or other forms of technical security assessments
  • Experience with building your own tools, preferably in Python or NodeJS
  • Experience and understanding of modern tech stacks and dynamic environments - containers, CI/CD pipelines, cloud environments
  • A pragmatic approach to solving security issues in ways that achieve the best effect within the organization
