Job description:

Architecture & Design:

  • Own the end-to-end solution architecture across Production Scheduling, Production Execution, and Allocation Rules Engine modules
  • Define and enforce architectural patterns: three-tier (Next.js → Azure Functions → Azure SQL), RTK Query slice conventions, schema name spacing, and DEP integration contracts
  • Lead database schema design (SSDT projects, Azure SQL) and API contract definition (OpenAPI/Swagger) across all modules
  • Architect real-time subsystems: SignalR hub for check-weigher events, Azure Service Bus Premium queuing for NAV output posting, and retry/dead-letter strategies
  • Design the Allocation Rules Engine evaluation pipeline for sub-200ms P99 latency and batch-evaluation throughput

Required skills :

  • 9+ years of software development experience, with 3+ years in a Solution Architect or Lead Architect role
  • Deep expertise in Azure-native architectures: Azure Function Apps (isolated worker model), Azure SQL, Azure Service Bus, Azure AD / MSAL (OAuth2/OIDC)
  • Strong C# .NET 8 — Azure Functions, Entity Framework Core, xUnit testing, REST API design
  • Strong React / TypeScript / Next.js 15 — App Router, RTK Query, Tailwind CSS, component library patterns
  • Azure SQL / SQL Server schema design — SSDT projects, query optimization, multi-tenant schema isolation
  • Experience integrating with ERP systems (Microsoft Dynamics NAV / Business Central strongly preferred)
  • Proven experience designing real-time systems (SignalR, WebSockets, or equivalent)
  • OpenAPI/Swagger specification authoring and API contract-first development
  •  

AI & Tooling

  • Hands-on experience with Claude Code, GitHub Copilot, or equivalent AI coding assistants in production development workflows
  • Demonstrated ability to prompt LLMs effectively using structured specifications and to critically evaluate generated output
  • Familiarity with AI-assisted test generation and automated code review tooling

Architecture & Process:

  • Track record delivering complex, multi-module web applications end-to-end
  • Experience with message-driven integration patterns (Azure Service Bus, event-driven architecture, dead-letter handling)
  • Observability and monitoring: Application Insights instrumentation, custom metrics, alerting design
