Applied Scientist II

Join the Microsoft Turing Team and help shape the future of enterprise productivity through cutting-edge AI. We are responsible for the core systems that power the Microsoft 365 Chat Copilot for enterprise – a groundbreaking AI assistant used by hundreds of millions of users around the world. As an Applied Scientist II (M365 Copilot-Turing Team) on our team, you’ll work side by side with world-class scientists and developers to bring large language models (LLMs) to life, at enterprise scale, leveraging your skills and experience to help build the platform that powers Microsoft’s enterprise Copilots. As a fast-growing team with a wide breadth of opportunities, projects are assigned based on your particular interests, experiences, skillset and background. These projects can span across areas such as: building the core orchestration for M365 Copilot, developing advanced capabilities such as code and image generation, enabling multimodal interactions, or pioneering AI-driven computer use and shipping of cutting-edge technology for 100s of millions of users. We’re not just training and applying models — we’re building intelligent systems that run them. This is your chance to engineer the critical infrastructure, platforms, and features that power the Microsoft Copilot — with a direct impact on how the world works. As an Applied Scientist II (M365 Copilot-Turing Team), you will: - Advance the state of the art in model training - including post-training methods such as fine-tuning and reinforcement learning, high-quality data curation, and experimentation with frontier models - Build and deliver model-driven features from concept to production - spanning model development, evaluation, metrics, and A/B testing - Evolve our orchestrator to reason more effectively, respond faster, and support new capabilities in multi-modality, agent-based systems, and beyond We’re hiring applied scientists who are passionate about deep learning, NLP (Natural Language Processing), multimodality model, and model optimization. Come build the next generation of AI with us.
