Senior AI Engineer

As a Senior AI Engineer in the Office AI team, you will help lead the evolution of Office productivity through AI-driven experiences and services across key applications. The team builds the core platforms and experiences that bring large language models (LLMs) and real-time intelligence into Office applications, combining the power of LLMs with enterprise data and native integration to streamline content creation, navigation and comprehension. We are looking for a creative Senior AI Engineer who will collaborate with software engineers, researchers, and product managers to express product needs as well-defined machine learning problems, push the state of the art in LLMs and bring prototypes all the way to planet scale production. Help drive the culture shift to AI first development and mentor junior engineers on the team. You’ll build the engineering that makes AI work in production: you will build APIs, platforms and services around AI features; design data pipelines and feedback loops; deploy and finetune state of the art deep learning models; orchestrate prompts and tools; and monitor AI specific signals—such as drift, hallucinations, safety and cost—alongside traditional service reliability metrics. Join us to empower people through AI, bringing cutting edge deep learning into everyday work at scale.
