Sr. Software Developer - Backend (AI Platform)

TripArc • Toronto, ON

8h • Hybrid

About The Position

TripArc is building an AI-powered vacations booking platform that will put 10,000+ pre-packaged, instantly bookable itineraries in the hands of North American travel advisors. The work spans both greenfield and existing platforms. You'll be building new Angular MFEs, AI agent pipelines, and integrating with MongoDB-backed catalog infrastructure for the Vacations Platform, while extending and integrating with the mature ADX booking platform and the new Product Builder. You will own your work end-to-end: design through deployment, in close collaboration with Product, QA, and your pod. The ADX Vacations Platform targets significant revenue in the form of gross bookings and this pod is building the core of it. The decisions made now will define the platform for years. You won't be inheriting someone else's design. You'll be making it.

Requirements

• Backend development experience, building services, pipelines, and data layers.
• Comfortable designing event-driven integrations with Azure Service Bus and NServiceBus.
• Confident in both SQL Server and MongoDB Atlas.
• Careful consideration of API design and its implications for services called thousands of times a day.
• C# / .NET Core (5+ years)
• SQL Server (complex schemas, query optimization)
• MongoDB Atlas — schema design, aggregation pipelines, Atlas Search
• RESTful API design, Entity Framework

• Building the Chorus AI agent system — 8 agents across Generation and QA pipelines — that auto-generates, validates, and enriches itinerary content at scale.
• Building Search & Browse, and Itinerary Detail experiences advisors use to find, evaluate, and customize pre-built trips.
• Implementing the NL Search API connecting MongoDB to ADX or direct to Product Builder using MCPs.
