A challenging task

Doing engineering at our scale is a significant and rewarding technical challenge. Our production system consists of 180 services of different sizes, posing plenty of challenges.

  • A lot of Java and Kotlin, among a variety of programming languages such as Ruby on Rails, Scala, Elixir, PHP...
  • Prometheus and Grafana for metrics and alerting.
  • CI/CD pipelines using Jenkins, deployed to Kubernetes clusters hosted in our data centres in Amsterdam.
  • Kafka and RabbitMQ as message queues, the former is now increasingly used for event-driven systems.
  • Different databases for different needs: MySQL, Postgres, Cassandra, MongoDB, Elastic Search...
  • GraphQL (implemented in Scala & Sangria) for our mobile and web APIs

A convincing background

We have offices in various parts of Europe (Hamburg, Munich, Vienna, Barcelona, Porto and Valencia). XING employees come from more than 30 different countries and bring their
collective experiences and culture to work every day. Some of us studied computer science, while
others come from other fields or don't even have a degree-level qualification. The key common
ingredient is a willingness to learn and grow.

  • you care about the craft of software development and strive to build testable, predictable and simple code,
  • you want to tackle the engineering challenges that come with building systems at scale (highly available, low latency and high throughput),
  • you are curious and interested in learning new languages and frameworks,
  • you have a good sense of humour and keep calm in difficult situations,
  • you value transparency, honesty, humility and helping your teammates grow.
