Informacje o stanowisku

At Silent Eight, we develop our own AI-based products to combat financial crimes that enable things like money laundering, the financing of terrorism, and systemic corruption. We’re a leading RegTech firm working with large international financial institutions such as Standard Chartered Bank and HSBC. Join us and help make the world a safer place!

We are currently looking for a Java Developer to join the IRIS 6 Team.

IRIS 6 is the next iteration of our flagship identity matching platform — a system composed of multiple products responsible for comparing identities and screening individuals against sanctions and watchlists. Most of the platform has been rebuilt from scratch over the last year, and it is currently under active development with new functionalities being added. The team puts strong emphasis on performance, scalability, and simplicity of solutions — and works on non-trivial, technically challenging problems.


  • Strong experience with Java and the Spring ecosystem (Spring Boot / Spring Framework), including building and maintaining production-grade applications.
  • Hands-on experience with relational databases and persistence layers, preferably PostgreSQL with Spring Data JPA / Hibernate, and familiarity with schema/version management tools such as Liquibase.
  • Good understanding of software engineering best practices, including clean code, code reviews, testing, and working within CI/CD pipelines.
  • Ability to work effectively in a collaborative, cross-functional environment, communicating clearly with product, QA, architects, and support teams.
  • Experience working in an Agile setup and using tools like Jira to estimate work, track progress, and manage priorities transparently.
  • Experience with a frontend stack (Angular or React) or Python is a strong plus.
