  • Experience with one or more of the following programming languages: Python, TypeScript or JavaScript, C#, Java.
  • Good understanding of backend microservice development, including REST APIs, asynchronous messaging (Kafka or similar), and data storage patterns such as NoSQL.
  • Hands-on experience with one or more cloud providers, including AWS, Azure, and/or Google Cloud Platform.
  • Excellent verbal and written communication skills.

Benefits
