scheme imagescheme imagescheme image
We are CHECK24 - the leading German comparison platform with 15 million customers and over 40 products in comparison.
Have you ever wondered how it is possible to develop a high-performance and highly available fintec comparison platform? In doing so, you should know that loans are highly individual, and we process a large number of customer applications together with our financial partners create tailored individual offers for our clients. This pushes the boundaries of classical APIs and architectural approaches, requiring us to find creative and smart solutions.
A highly distributed architecture and cloud-native applications form the basis for a robust, resilient and highly scalable platform capable of quickly implementing product requirements while staying technically up-to-date and driving innovation. We rely on both modern and established technologies as well as the continuous evaluation of trends and technologies of tomorrow to find the cheapest and fastest loan for our customers.
In terms of technology, we use Java 21 / Spring Boot 3, Gradle 8, React 18 / Angular 17, Kafka/ActiveMQ, Redis, Elasticsearch, MongoDB/Oracle/Percona, CICD, Flux/Gitops, K8s/Rancher, Prometheus/Grafana and many more.

With over 500 individual deployments, >16 terabytes of RAM, >1600 CPUs, > 600TB disk space and a well thought through setup we ensure our platform can handle high demand.
We live a strong DevOps culture and, as developers, are responsible for the entire development process from the late stage of requirement management to operations (PaaS) according to our guideline "You build it, you run it." Through a high degree of automation and close collaboration, we achieve an average of 45 feature releases per day.
Knowledge building (trainings, tech talks, post-mortem reviews), and a personal development plan are deeply rooted in our value system.
