Backend Engineer - Agent Builder: Revit Integration

What we do:

Architects and engineers collaborate with our agents to design & engineer buildings 10x faster.

• First, we developed a system that transforms BIM data (the source code of buildings) into an AI-reasonable format.
• Now, we offer agents in SaaS + Service that build buildings with architects and engineers.

Tech Stack:

• .NET 8.0 / ASP.NET Core
• SignalR (real-time communication)
• RabbitMQ (message queuing)
• Entity Framework Core
• Revit API / Autodesk Platform Services
• MCP (Model Context Protocol)
• Docker/AWS ECS

What Need to be built

1. Model Context Extractor (Revit Add-in)Serialize current model state to JSON
   Send relevant context with each prompt

2. C# Code Generator Prompt EngineeringTemplate system for Claude
   Include Revit API constraints
   Transaction handling patterns

3. Dynamic Code Executor (Revit Add-in)Roslyn compiler integration
   Safe execution environment
   Result serialization

4. Session ManagerTrack Desktop App ↔ Revit pairings
   Handle disconnections gracefully
   Queue commands for offline Revit

Key Requirements:

• Proficiency in C# and .NET 8.0, with experience building scalable backend services using ASP.NET Core
• Strong understanding of message-driven architecture, including hands-on experience with RabbitMQ or similar queuing systems
• Experience with Entity Framework Core and working with relational databases in production environments
• Familiarity with real-time communication frameworks, particularly SignalR, for client-server messaging
• Demonstrated ability to build or integrate with Autodesk Revit API or similar CAD/BIM platforms
• Comfortable working with dynamic code execution and sandboxing, ideally using tools like Roslyn
• Experience developing or consuming add-ins/plugins for desktop software (e.g., Revit, AutoCAD, etc.)
• Exposure to cloud infrastructure, especially Docker and AWS ECS, for containerized deployments
• Strong software architecture skills—able to build reliable, event-driven systems with decoupled services
• Ability to work in fast-paced, experimental environments involving AI integrations and prompt engineering

Bonus: Experience with Claude, LLM-based code generation, or AI-powered developer tools
