  • Participate in design reviews, code reviews, and mentoring of junior developers

Must-Have Skills

  • Strong EF Core experience:
  • Query optimization, projections, and set-based operations
  • Managing concurrency tokens, tracking behavior, and transactional integrity
  • Proven experience designing and maintaining Azure Functions (including Durable Functions)
  • Experience implementing Outbox/Inbox patterns, idempotency, and message-driven architectures
  • Solid grasp of API versioning, pagination, ETags, and RESTful design principles
  • Hands-on experience with Azure Service Bus (topics, subscriptions, DLQs, message sessions)
  • Proficiency with App Insights, structured logging, and performance monitoring

Nice-to-Have Skills

  • Experience with Sagas / Process Managers and long-running workflows
  • Exposure to Terraform or Bicep for IaC (Infrastructure as Code)
