Working under Oracle’s direct architectural oversight, the engineer will build the core middleware layer connecting Microsoft 365 environments with enterprise intelligence platforms. The work will focus on executing the Graph API Sync Layer, developing Admin Backend configuration services, managing the API Gateway layout and providing data-connectivity hooks for a proactive Agentic AI Orchestrator.\nKey Responsibilities and Scope of Work\nGraph API Tasks Sync Service: Develop a timer-triggered, server-side backend service providing bidirectional synchronisation between Siebel CRM Actions/Coverage Approval Requests and the Microsoft Outlook Tasks surface (Microsoft To Do) through the Microsoft Graph Tasks API.\nEndpoint Detection and Dual Support: Implement tenant-level detection to dynamically manage connectivity across the legacy Exchange Tasks endpoint (/me/tasks) and the modern Microsoft To Do API (/me/todo/lists/{listId}/tasks).\nWebhook and Subscription Management: Configure and maintain Microsoft Graph subscription models, webhooks, delta queries and event-change notifications to process high-throughput, real-time message contexts.\nAdmin Configuration Backend: Deliver the programmatic foundations of the administrative configuration dashboard, supporting settings for per-user sync lists, conflict-resolution policies such as Last-Write-Wins, deletion handling through soft or hard deletes and custom extended-property schema maps.\nAgentic AI Integration and Tool Mapping: Support the Agentic AI Orchestrator by exposing registered write-back target data definitions as dynamic tools through a Model Context Protocol (MCP) framework.\nToken Resilience and Queue Management: Manage delegated token flows (Tasks.ReadWrite) at a per-user scale using Nested App Authentication (NAA), and establish offline retry queues that preserve pending data changes during unexpected network disconnections.\nRequirements\nRequired Technical Skills and Qualifications\nCore Backend Stack: Solid backend software-engineering experience using Node.js and TypeScript.\nMicrosoft 365 and Graph Ecosystem: Deep hands-on proficiency with the Microsoft Graph API framework, specifically covering Mail, Calendar, Tasks and People domains.\nIdentity Management: Strong familiarity with Microsoft Entra ID, OAuth 2.0 delegated/application permission models and token lifecycle management.\nSync and Queue Engineering: Understanding of asynchronous processing, background workers, queuing mechanisms, exponential backoff rules and complex data-conflict synchronisation.\nPreferred Skills\nFamiliarity with enterprise API-integration patterns for LLM execution layers.\nFamiliarity with prompt-context assembly.\nFamiliarity with structural API Gateway management.\n264/103-104 Pratap Nagar, Sanganer,
