Your career in Fintech
Java Backend Developer (m/f/d)
As a Java Backend Developer, you will work on a platform that connects to thousands of banks and processes large volumes of financial data. This is not a greenfield project, but a system that continuously evolves under real-world constraints.
About the job
Your tasks
- Building and maintaining integrations with European banking interfaces (APIs as well as legacy protocols like FinTS/HBCI)
- Handling inconsistent and unreliable third-party systems
- Developing backend features in a high-throughput, data-intensive environment
- Improving performance, stability, and data quality across our platform
- Debugging complex edge cases that arise from real banking data and integrations
- Writing clean, maintainable code with solid test coverage
- Collaborating closely with Product, Support, and other engineering teams to ship features that work reliably in production
About you
Your profile
- Completed degree in computer science, software engineering, or a comparable qualification.
- Solid experience with Java or Kotlin in backend development (ideally with Spring Boot)
- Experience building and maintaining REST APIs in production
- Good understanding of relational databases (PostgreSQL or MySQL)
- Ability to write clean, maintainable, and well-tested code
- Confidence to work independently on features while collaborating within a team
- Interest in understanding and solving real-world system behavior (not just happy-path coding)
The following qualifications are not essential, but would be a plus:
- Experience with financial APIs (PSD2 / XS2A) or FinTS/HBCI
- Familiarity with Docker and containerized environments
- Experience with CI/CD pipelines
- Exposure to Kubernetes or cloud environments (e.g. AWS)
