  • Experience with SQL databases such as PostgreSQL, MySQL, or Oracle.
  • Basic understanding of microservices architecture.
  • Experience with Git and standard software development practices.
  • Understanding of unit testing and debugging.
  • Ability to work in a team and communicate clearly on technical topics.
  • Strong spoken English — Upper-Intermediate / Advanced level, B2+ or higher.

Nice to Have

  • Experience with Spring Security or Spring Data.
  • Basic experience with Docker.
  • Familiarity with messaging systems such as Kafka or RabbitMQ.
  • Experience working with cloud services such as AWS, Azure, or Google Cloud.
  • Previous experience in fintech, e-commerce, SaaS, logistics, or enterprise software projects.

What We Offer

  • Remote-friendly cooperation format.
