Poland · Contract · Mid-Senior

We have an exciting opportunity with one of our clients in Poland who are looking for a Senior/Staff-level position with a leading company in the Fintech industry. This is a freelancing contract for 6 months based in Poland.


The role requires a strong background in Java with the Spring framework (which is essential), and we're looking for someone with experience in data-heavy platforms. If you have hands-on experience with Spark, Kafka, and Flink, that would be a huge plus. Additionally, any familiarity with Neo4j or Python would certainly be valuable!

Key Highlights:

  • Strategic system design experience is needed
  • You’ll be working on a team focused on large-scale data platforms
  • Poland-based candidates are preferred, but remote work is available
  • Banking industry experience is an advantage but not a requirement
  • This position is perfect for someone at the Senior or Staff level
