AI has created an unprecedented opportunity to make work better for hundreds of millions of people. Microsoft’s productivity division is hiring a Principal Applied Scientist to help ensure we maximize this amazing opportunity. Our scientists collaborate closely with people across Microsoft’s product teams and Microsoft Research to see their ideas realized in products and services like M365 Copilot, Word, Teams, Windows, Surface, OneDrive, SharePoint, Windows, Surface, Outlook, and PowerPoint. They also contribute back to the scientific community through peer-reviewed publications at top venues, scientific presentations, and beyond.

We are looking for a Principal Applied Scientist who is creative, self-driven, curious, people-oriented and comfortable defining a path through ambiguity towards high-level goals. This role is ideal for candidates passionate about building real-world systems that unify different textual modalities and agentic experiences to power next-generation user experiences across devices and platforms.

As a senior member of the team, you will be a tech lead and drive innovation across model architectures, training, and deployment. You will play a key role in converting cutting-edge research into practical applications and experiences for users across the globe by proven skills in product experiences: understanding requirements, setting partner expectations and communicating across team boundaries.

Research areas of interest include but are certainly not limited to reinforcement learning, agentic systems multimodal modeling, post-training techniques and their application, human-centered artificial intelligence (AI), domain-specific large language model (LLM) applications (e.g. long-form writing assistance), personalization, computational social science, memory, agentic retrieval-augmented generation (RAG), real-time AI systems, collaborative AI, privacy-preserving AI, trustworthy AI, data-centric AI, AI flywheels, and multilingual AI.

Microsoft’s mission is to empower every person and every organization on the planet to achieve more. As employees we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.
