  • Build scalable microservices architectures deployed on Azure Kubernetes Service (AKS)
  • Containerise services with Docker and manage deployments using Kubernetes
  • Implement event-driven systems leveraging Azure services (Event Hub, Service Bus)
  • Develop and optimise RESTful APIs with proper versioning, pagination, and error handling
  • Model data and implement persistence using Entity Framework and relational databases
  • Automate deployments using ArgoCD, Bicep (IaC), and GitOps workflows
  • Collaborate with front-end developers and cloud architects to deliver end-to-end solutions

Requirements

  • 5+ years' professional backend/cloud development experience
  • Strong C#, .NET (Core/6+) and API design skills
  • Hands-on experience with Azure services (AKS, App Services, Functions, Event Hub, Service Bus, Key Vault)
  • Solid understanding of microservices and containerisation (Docker, Kubernetes)
  • Experience with Entity Framework and relational databases (SQL Server, PostgreSQL)
  • Familiarity with CI/CD and deployment automation (ArgoCD, Azure DevOps/GitHub Actions)
  • Knowledge of Infrastructure-as-Code (Bicep or ARM) and GitOps workflows

Nice to have

  • IoT data ingestion and edge-to-cloud integration experience
  • Working knowledge of NoSQL databases (Cosmos DB, Redis)
  • Cloud security best practices (OAuth2/OIDC, secrets management)

GCS is acting as an Employment Agency in relation to this vacancy.
