CHECK24 Baufinanzierung brings innovation and "online" to a market traditionally dominated by on-site services. Since 2014 we help our customers to find the most suitable way to finance their new home. We are looking for smart and highly motivated developers who are ready to jump on one of the many daily CI/CD trains heading to production.

We work with the following technologies and tooling: Java 17, Spring Boot 2, Spring Framework 5, Vue.js, ECMAScript 2019, Elasticsearch, Redis, RabbitMQ, Gradle and many others.

Interested? Check the snippet below:

public class UserLogicBean {
   // A Spring Data JPA repo
   private UserEntityRepository repo;

   public boolean hasPermission(String username, PermissionEntity permission) {
         return retrieveUserPermissions(username).contains(permission);

   @Transactional(readOnly = true)
   public List<PermissionEntity> retrieveUserPermissions(String username) {
      return repo.findByUsername(username).getPermissions();
