Project description:We are building the next-generation version of our core data synchronization system. This platform is responsible for the seamless exchange of delivery and return data between global suppliers and retail stores. You will be joining a product-focused team to develop high-performance backend components, APIs, and integration pipelines that ensure our logistics data remains accurate, scalable, and reliable.Main responsibilities: Design, implement, and maintain backend services and architectural components using modern .NET. Build and evolve APIs and integration endpoints to handle complex data mapping and transformation for deliveries and returns. Develop background workers, message queues, and scheduled jobs for data reconciliation. Own database design, schema evolution, indexing, and query optimization to ensure high performance. Write clean, testable code; implement robust logging, metrics, and tracing to ensure system observability. Independently manage the full development lifecycle - from initial implementation and code review to CI/CD and production release. Work actively within an Agile/Scrum team, refining requirements alongside Product Owners and Architects. Nice-to-have Experience with Distributed Systems and heavy integration flows (EDI, partner APIs). Knowledge of Messaging Platforms (Azure Service Bus, RabbitMQ, or Kafka). Experience with Cloud Infrastructure (Azure/AWS) and Infrastructure as Code (Terraform). Familiarity with the Logistics or Retail domain (inventory, orders, reconciliation).
