Must have:

- C# on modern .NET (8 or later) with ASP.NET Core Web APIs. The RFP says new components should be contemporary .NET unless a documented constraint says otherwise, so this is the primary skill.

- Working comfort in legacy .NET Framework 4.x. The VAX booking engine mixes .NET Core and .NET Framework.

Itinerary

Builder and Smart Recommendations sit on booking-engine pages, so developers will need to read that code and make integration changes, even if new work stays on modern .NET.

- Azure application services: App Service or Container Apps, Functions, Azure Cache for Redis, Key Vault, and Azure SQL or Cosmos DB. The solution runs inside ALGV/Trisept's hub-and-spoke Azure setup, so experience with private networking and managed identity helps.

- Strong TypeScript plus React

- Hands-on LLM application work: calling Azure OpenAI or similar, structured outputs, tool/function calling,



and retrieval (RAG) with something like Azure AI Search. Each pod builds an agent (FindDeals, BuildItinerary, Recommend), so this isn't optional.

- Unit and API testing as part of their own work, and CI/CD pipeline experience.

Nice to have:

- Optimizely CMS development. The Deal Finder page lives on the Optimizely content site, so at least one or two developers in the Deal Finder pod should have it.

- Microsoft Agent Framework or Semantic Kernel (consistent with the Technical Architect JD).

- Embedding a shared UI component into multiple host applications (web components, micro-frontends).

- Accessibility (WCAG) implementation experience.

- Travel, booking, or pricing domain background.
