Senior Principal Researcher - Microsoft Research AI Frontiers

The Microsoft Research AI Frontiers Lab is on a mission to push the boundaries of what's possible in Artificial Intelligence (AI) — advancing capabilities, efficiency, and safety through breakthroughs in agentic model and systems. Our previous work spanned Small Language Models (Phi, Orca), Synthetic Data Generation (AgentInstruct), Computer Use Models (Fara), and agentic AI systems (AutoGen, MagenticOne, OmniParser), with real-world impact at scale. We're looking for Senior Principal Researcher to join us in Redmond, WA or New York City, NY and help shape the future of agentic AI. In this role, you'll develop and implement cutting-edge training methodologies for large language and multimodal models with advanced agentic and reasoning capabilities. Your work contribute to cutting edge research and directly influence state-of-the-art systems used by millions of people worldwide. Our current focus areas include: Reasoning and inference-time compute; Action models for automating computer use tasks; Memory and long-horizon task execution; Multi-agent training and orchestration. The AI Frontiers Lab is a uniquely dynamic environment: multidisciplinary by design, connected to top academic institutions, and committed to open publication. You'll have access to rich, diverse real-world data and the runway to experiment, publish, and make your mark on one of the most consequential fields in technology.
