• Participate in code reviews, providing constructive feedback to ensure maintainability and adherence to coding standards
• Develop and maintain unit and integration tests to ensure reliability and stability of delivered features
• Work with messaging systems and asynchronous communication patterns to support distributed architectures
• Continuously identify opportunities for technical improvement and contribute to the evolution of the technology stack

Our requirements

• Hands-on experience with Apache Kafka for event streaming, asynchronous messaging, and building event-driven architectures
• Strong proficiency in at least one modern frontend framework — Angular or React — including component-based architecture and state management
• Strong communication skills and the ability to work effectively in an international, Agile team environment
• Proficiency in English (B2+), both written and spoken

Optional

• Experience with Terraform for infrastructure as code and automated provisioning of cloud resources
• Familiarity with Microsoft Azure cloud platform and its core services
• Working knowledge of Python for scripting, automation, or secondary application development
