Database Reliability Engineer

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.

Engineering at Klarna is an inspired, customer focused community, dedicated to crafting solutions that redefine our industry. Working 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.

Our engineers make some of the most significant decisions for the company and we are looking for bold, open and curious database engineers. As a Klarnaut, you’ll be inspired to contribute to the growth of Europe’s most highly valued fintech and your work will reach millions of users.

Want to be part of the change? We're expanding our multi-national database team in Berlin, with database reliability engineers.

“In other words, the effective DBRE functions by empowering others and guiding them, not functioning as a gatekeeper.”

Who we are...

We are a multi-national team of DataBase Reliability Engineers based in Berlin. Most of us have a database administration background with a longtime experience of managing relational databases. We believe that the role of the database administrator needs to  change. We believe that instead of running databases for others we can contribute much more to our company’s ambitious goals by enabling Klarna’s product teams to run their own databases in the most efficient, secure and compliant way. We simply provide the tools they need to do just that. We don’t do the on-call for someone else’s databases any longer. We rather engineer the reliability of databases.

What you will get to do...

Klarna’s data is to a very large degree stored in hundreds of RDS instances and clusters on AWS. These databases have to meet the high requirements of a company from the online payment and banking sector with respect to performance, availability, security and compliance. Many hours have been and will be invested by our product and development teams into the setup and maintenance of these databases. Hours, the teams cannot invest into the development of the core features of the products and services they are responsible for - You are going to help change that for them.

You are going to implement core tools that abstract the management of databases by automating its deployment, monitoring, and maintenance in the cloud in a way that their setup fulfills compliance rules and best practices. Tools that should provide the capability to integrate into their own deployment pipeline.

Additionally, you will improve the accessibility of database metrics and their interpretation by providing visualization tools, empowering root-cause analysis and predictions.

You will also, through knowledge transfer, mentor teams with their decisions of which database technology to use, and how to better use it, by improving their understanding of database modeling, tuning, and maintenance.

You should have...

  • Working experience with automation of database management processes, preferably using a programming language (i.e. Python).
  • Hands-on experience with optimization, tuning, configuration, and monitoring of databases, preferably PostgreSQL
  • Working experience with AWS services in general and AWS database technologies in particular (preferably RDS for PostgreSQL, Aurora)
  • Strong analytical skills and the ability to understand complex systems
  • Excellent team spirit and a healthy appetite to learn and try out new things
  • Great communication skills and the will to see things from a customers perspective

You might also have...

  • Good knowledge of database scaling techniques for high-performance databases, like proxies, caches, master-replica setups, etc.
  • Good knowledge of disaster recovery methods and configuring databases for high availability
  • Good knowledge of using the Continuous Delivery Pipelines with Git & Jenkins
  • Good knowledge of CloudFormation, Ansible or Terraform (or similar tools)
  • Good knowledge of SQL query performance optimization
  • University degree in Computer Science, or similar technical field, or equivalent practical experience
