3+ years of professional experience in software engineering and at least 1 year of experience with Kotlin and Spring Boot for scalable application development. Expertise in PHP (Symfony) is beneficial but not mandatory, as our current systems are PHP-based and we will work in a hybrid environment. A solid understanding of testing frameworks. A solid knowledge of SQL and relational databases. A basic understanding of messaging concepts and patterns in distributed systems (e.g., Kafka, RabbitMQ). Experience using Docker to run your application and have a basic understanding of automation and deployment of applications into cloud infrastructure (e.g., GitLab pipelines, AWS, Azure). Experience in frontend development is a plus.
