  • .NET 10 / ASP.NET Core Web API
  • Entity Framework Core with Azure SQL
  • .NET MAUI (iOS & Android) - offline-first design
  • Angular 21 (strict TypeScript)
  • DevExpress DevExtreme (v25)
  • Microsoft Azure (App Services, Azure SQL, Blob Storage, Key Vault, Application Insights)
  • Infrastructure as Code (Bicep)
  • Azure Entra ID (authentication & RBAC)

  • Vitest & Playwright (frontend and E2E testing)

Desirable Experience:

  • Power BI report templating
  • Azure Fabric / Data Lake familiarity
  • Geospatial or mapping APIs (Google Maps preferred)
  • iOS exposure (ARKit / LiDAR / sensor APIs)
  • Experience in regulated or security-sensitive environments

What They’re Looking For

  • Strong expertise in modern .NET
  • Proven experience with modern Angular (v15+)
  • Hands-on Azure architecture and deployment experience
  • Experience implementing Infrastructure as Code
  • Experience integrating Azure Entra ID
  • Strong REST API design knowledge
  • Experience implementing CI/CD pipelines
  • Security-first mindset with strong attention to detail
  • Ability to work independently within defined architectural standards
  • Clear and confident communication skills

Highly desirable: experience with DevExpress / DevExtreme.

Why This Role?

This is a rare opportunity to shape a foundational cloud platform from day one using the latest Microsoft stack. You’ll work in a disciplined, enterprise-grade engineering culture where security, performance, and quality are non-negotiable - while also contributing to a wider innovation strategy that will evolve beyond the initial product.
