What you will do

Engineering is rapidly growing and the Infrastructure Security team is looking for people passionate about automating and embedding security to protect cloud architectures on the infrastructure level.

If you today work as a developer, software engineer or perhaps a QA engineer, are self-driven and experienced in working with Python and cloud architectures such as AWS and want to lean into architecting, this is a position for you. You will get a lot of opportunities to work with engineering teams to build scalable and API consumable solutions for securing our staging and production environments. We provide a mentoring and competence track specific for you to get you up to speed.

Our mission in the InfraSec team is to protect Klarna systems by providing security services as part of the standard deployment infrastructure platform; thus automating away security for our engineering teams.

We are therefore looking for new colleagues who want to work on improving the security of our infrastructure components (i.e., networks, systems, containers, orchestration layers and CI/CD pipelines).

    • Solving security challenges in the cloud
    • Integrating automated security features in the deployment and provisioning of services
    • Auditing the infrastructure to identify security problems
    • 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

You should have

    • Experience in working with a micro-services architecture, e.g. AWS
    • Hands-on experience in building API-based tools
    • Experience in working with containers
    • Experience in building CI/CD pipelines
This is an exciting time to join our InfraSec team as we are growing and exploring new areas within the security domain. We know that diverse teams are strong teams, and welcome those with alternative identities, backgrounds, and experiences. Our team includes women, men, mothers, fathers, the self-taught, the college-educated, and people from all over the world. We’re a team of technically curious problem solvers. Come and join us.
