Someone excited by working in the latest technologies and on a range of breakthrough products in the Payment Processing and IoT field.

We are a team of 11 backend-oriented engineers operating on the JVM, where our primary language is Java. Our tech stack is focused around the Spring Framework and its surrounding ecosystem, which provides a versatile and established foundation for our projects. The use of a relational database in the backend world is almost a given, and the RDBMS of our choice is PostgreSQL. However, we also use several other services in our projects, such as Elasticsearch, Redis, and RabbitMQ.

The team is working on a number of digital services, primarily in the domain of (smart) home appliances, where we design and implement various APIs and solve interesting integration challenges. Our goal is to produce clean, maintainable, and well-tested code while applying domain-driven design and enterprise integration patterns. The nature of backend-oriented work also puts us in a position to collaborate with many other teams within our organization – from Mobile and Web to DevOps, and naturally the QA.
