Medior Software Engineer (C# .NET)

Sarajevo, Bosnia and Herzegovina

The role

We are looking for a Medior .NET Software Engineer to join our long-term partnership with ICA Sverige – Customer & Retail Solutions, within the Engineering Store Backoffice organization.

This is a full-time, on-site position in Sarajevo, with a planned start date in November 2026.

You will join the Store Reference Data Hub (SRDH) team, working closely with Swedish colleagues on business-critical systems supporting the daily operations of ICA stores.

Project

The Store Reference Data Hub (SRDH) is a backend and integration-heavy platform responsible for processing and distributing store-related data, including prices, assortment, and other store settings.

The platform acts as a bridge between store-facing applications and multiple downstream systems, including point-of-sale systems, electronic shelf labels, scales, waste-management solutions, and external suppliers.

The system processes large amounts of data and relies heavily on microservices, event-driven architecture, asynchronous messaging, APIs, and system integrations. Reliability and stable data flows are particularly important, as issues can directly affect store operations. 

The work includes

  • Developing new features and maintaining existing backend services using C# and .NET
  • Working with microservices and event-driven architecture
  • Developing, maintaining, and consuming REST APIs
  • Working with SQL and data-intensive backend applications
  • Publishing and consuming messages across distributed systems
  • Working with asynchronous messaging patterns, including queues, topics, publishers, and consumers
  • Maintaining integrations with internal and external systems
  • Troubleshooting application, integration, and production issues
  • Analyzing logs, application behavior, database data, and code to identify root causes
  • Ensuring reliable data flows and implementing sustainable solutions to technical issues
  • Working closely with developers, testers, the Tech Lead, Product Owner, and other ICA teams
  • Contributing to technical improvements and transitions within the platform
  • Working within a collaborative Scrum/Agile environment


Requirements:

  • 3 – 6 years of professional software development experience
  • Strong hands-on experience with C# and .NET
  • Experience working with modern .NET applications
  • Strong experience with SQL
  • Hands-on experience developing and consuming REST APIs
  • Hands-on experience developing and maintaining microservices
  • Good understanding of event-driven architecture and asynchronous messaging
  • Understanding of service dependencies and contracts between integrated systems
  • Experience troubleshooting backend applications, integrations, and production issues
  • Ability to systematically investigate technical problems and identify root causes
  • Experience with Git/GitHub
  • Experience working in Scrum/Agile environments
  • Ability to work independently while collaborating closely with other team members
  • Strong problem-solving and communication skills
  • Curious, collaborative, adaptable, and open-minded approach to development
  • Fluent English communication skills

Nice to have:

  • Experience with Azure Service Bus, including Queues and Topics
  • Experience with MassTransit
  • Experience with Kafka or similar messaging technologies
  • Experience with Microsoft Azure
  • Experience with Azure Key Vault
  • Experience with gRPC
