As part of the M365 Copilot team, we are building enterprise-grade agentic web infrastructure, enabling advanced browser and search tools for both public and private web ecosystems. As the web remains the largest and most dynamic data source for AI, M365 Copilot requires solid infrastructure with the ability to retrieve, process, and ground information from the web with unprecedented accuracy, security, and compliance. The team's mission is to build this critical infrastructure to enable M365 Copilot to stay ahead of the competition. By leveraging Microsoft's infrastructure like Bing, open-source technologies, and learnings from industry leaders, we will build scalable, extensible, intelligent and high-quality services, all while adhering to enterprise security and compliance standards. This is a unique opportunity to shape the future of AI-powered web interaction and information retrieval at scale.
