Build and enhance an internal AI agent platform that empowers Cisco employees to interact with enterprise knowledge through conversational interfaces (Webex, web). Design and develop multi-agent workflows powered by Large Language Models (LLMs) to automate knowledge retrieval, content generation, and competitive analysis at scale. Architect resilient data ingestion pipelines that synchronize and index unstructured content from sources like SharePoint, Confluence, and internal wikis through Microsoft Graph and other enterprise APIs. Collaborate with product managers, AI/ML engineers, and InfoSec partners to deliver secure, observable, and high-quality solutions in an agile environment. Contribute to architecture, retrieval-augmented generation (RAG) design, prompt engineering, and CI/CD practices that support rapid, reliable delivery of AI features. Succeed in this role by shipping maintainable, production grade agentic systems that measurably improve employee productivity and advance Cisco's AI enabled platform strategy.
