ML Engineer for Microsoft Office AI team to build core platforms and experiences integrating LLMs into Office applications. Responsibilities include developing intelligent features, deploying AI solutions on Azure, and productionizing ML models at scale, focusing on agentic systems and their underlying infrastructure.

What you'd actually do

  1. Ship features with PM & Engineering. Co-own scenario goals; translate product requirements into scientific plans and productionized solutions that meet quality/latency/cost targets.
  2. Generative AI and advanced technologies. Apply knowledge of generative AI, large language models, and modern frameworks to develop intelligent features and automation within the service.
  3. Azure platform integration. Deploy, integrate, and manage AI powered solutions within the Azure ecosystem, ensuring security, scalability, and compliance with best practices.
  4. Continuous learning and mentoring. Stay current with advances in generative AI and software engineering. Invest time in learning new tools and frameworks, propose improvements to build processes, and share knowledge with colleagues.

Skills

Required
