Senior Software Engineer - Core AI

The Experimentation Platform (ExP) team powers Microsoft’s end-to-end experimentation ecosystem, enabling product teams across the company—including Copilot, Bing, Office, Windows, Edge, Xbox, and Azure — to make data-driven decisions at massive scale. We build the experimentation framework, compute platform, data pipelines, agent-driven automation and insights and that run millions of experiments each year. We focus on delivering world-class reliability, scalable experiment execution, transparent compute fundamentals, automated workflows, and AI-assisted agentic capabilities that accelerate experimentation velocity across Microsoft. This role offers the opportunity to build modern user experience, high-performant distributed systems, modernize a mission-critical experimentation stack, integrate AI-driven agents, and improve end-to-end fundamentals such as efficiency, observability, and resiliency. As a platform software Engineer, you’ll collaborate with cross-functional teams across engineering, data science, and AI to deliver a seamless experimentation experience at global scale.
