Overview
Come and be part of a dynamic team focused on securing cutting-edge AI and cloud technologies in a rapidly evolving threat landscape. We are leading new initiatives and research projects across AI Security, Identity Protection, and SaaS Defense, and this role offers a unique opportunity to help define the rules of the game. AI is transforming the way we interact with computers and machines and defining new cybersecurity problems and opportunities - we are looking for a researcher who can help us stay ahead of the curve. In this role, you’ll research and build defenses across AI systems, agentic protocols, Identity platforms, and SaaS applications. One day you might analyze a new class of AI prompt injection attacks or Agents abuse, the next you’ll be hunting through data or creating novel protection mechanisms for them. You’ll work closely with product teams to turn research prototypes into real security features. Join our threat protection research team and be part of a team who contributes to Microsoft’s most advanced and innovative security solutions.
