Lead Integration Engineer (Microsoft Ecosystem)

This role is responsible for architecting the deep tissue connectivity required for our RAG (Retrieval-Augmented Generation) services to securely and efficiently traverse complex enterprise data landscapes. The scope of work encompasses a multi-layered integration strategy: managing System-level data flows (storage and back-end), Service-level orchestration (logic and APIs), and UI-level integrations (extending the user experience within Microsoft platforms).

• Design end-to-end data movement strategies between Microsoft Cloud storage and internal vector databases, selecting optimal patterns (Webhooks vs. Delta Queries) based on latency and rate-limiting constraints
• Own the Microsoft identity lifecycle, including the implementation of Azure Entra ID (Active Directory) protocols, Service Principals, and complex conditional access scopes
• Develop high-performance MCP (Model Context Protocol) servers using Python and FastAPI to expose nested Microsoft Graph schemas to AI agents
• Serve as the subject matter expert on Microsoft system design to ensure the platform remains resilient against enterprise-scale throttling and service interruptions

• 7+ years of professional engineering experience with a track record of building complex, high-volume system integrations.
• Extensive experience managing multi-layered authentication (OAuth2, OIDC, SAML) within a Microsoft enterprise tenant.
• Proven ability to map internal and external data flows, ensuring a balance between high-fidelity data retrieval and strict enterprise security compliance.
• Expert-level proficiency in Python/FastAPI, complemented by the ability to deconstruct .NET/C# SDKs to understand native Microsoft data handling.
