Principal Researcher, Office Product Group

Microsoft Microsoft · Big Tech · Redmond, WA +1 · Applied Sciences

Principal Researcher role within the Office Product Group at Microsoft, focusing on advancing AI-powered experiences embedded in Microsoft 365 applications. The role involves designing, developing, evaluating, and deploying AI systems that can reason and act across tools and documents, with a strong emphasis on scaling these capabilities to a large user base. Key responsibilities include developing frameworks for AI component coordination, improving code generation, implementing fine-tuning and post-training for LLMs, designing evaluation strategies for real-world workflows, and collaborating to translate research into production-ready features.

What you'd actually do

  1. Support the development of frameworks that enable coordination and communication across multiple AI components, helping to facilitate task delegation, orchestration, and result validation scenarios.
  2. Apply and improve techniques for efficient code generation and transformation in low-resource environments, including adapting models to domain-specific languages, formulas, and structured or semi-structured data formats.
  3. Implement and iterate on fine-tuning and post-training approaches for large-scale machine learning models to enhance reliability, controllability, and readiness for production use.
  4. Contribute to the design and execution of evaluation strategies and benchmarks that reflect real-world Microsoft 365 user workflows, including participation in system-level and human-in-the-loop assessments.
  5. Collaborate with engineering and product management partners to help translate research ideas into scalable, production-ready features, with attention to user experience, performance, and responsible AI practices.
