What we are looking for
- 5+ years of backend engineering experience
- Strong hands-on experience with Java and Spring Boot

- Proven work with event-driven architectures (Kafka, RabbitMQ or similar) — this is essential
- Solid experience with relational databases (PostgreSQL, MySQL, Oracle…)
- Strong focus on code quality, testing, and maintainability
- Comfortable working with Git workflows and cross-functional teams
Nice to have
- Experience with DDD, CQRS, event sourcing or NoSQL
- Familiarity with TDD practices
- Experience with Docker, CI/CD pipelines and cloud platforms (e.g. GCP)
