Applied Scientist II

Come build the core of Microsoft Copilot for enterprise with the Microsoft Turing Team, where you'll join a collaborative group of applied scientists and engineers pushing the frontier of large language models (LLMs) to improve the productivity of hundreds of millions of users around the world. Our team is responsible for the core systems that power Microsoft 365 Copilot Chat, delivering intelligence, quality, and transformative new features. We work at the intersection of research and engineering—advancing orchestrator reasoning, training next‑generation models, and shipping impactful, model‑driven experiences in Microsoft 365 Copilot. We are hiring an Applied Scientist II who will contribute directly to this work. As an Applied Scientist, you will: Evolve our orchestrator to reason more effectively, respond faster, and support new capabilities in multi‑modality, agent‑based systems, and beyond. Advance state‑of‑the‑art model training—including fine‑tuning, reinforcement learning, high‑quality data curation, and experimentation with frontier model training. Build and deliver model‑driven features end‑to‑end—from development and evaluation to metrics and A/B testing.
