  • Strong product-oriented mindset, with end-to-end ownership of features and good collaboration within the team.
  • Proficiency in Java (preferred) or solid experience with similar backend programming languages.
  • Familiarity with messaging systems such as Kafka or RabbitMQ, and strong knowledge of relational databases (SQL).
