Senior Principal Researcher - Microsoft Research AI Frontiers

Microsoft is on a mission to push the boundaries of what's possible in Artificial Intelligence (AI) through its Research AI Frontiers Lab. The Senior Principal Researcher will develop and implement training methodologies for large language and multimodal models, contributing to cutting-edge research that influences state-of-the-art systems used globally.

Responsibilities:

• Lead and conduct cutting-edge research in agentic AI, translating insights into practical solutions that ship to millions of users — in close collaboration with researchers, engineers, and product teams
• Curate high-quality datasets and develop novel training algorithms tailored to agentic and reasoning tasks
• Design rigorous evaluation frameworks to benchmark model capabilities across reasoning, long-horizon tasks, and multi-agent scenarios
• Prototype and iterate on new agentic capabilities — from computer use and action models to memory and multi-agent orchestration
• Drive research from idea to publication, with opportunities to publish at top-tier venues and contribute to the broader scientific community
