Microsoft 365 Copilot is a groundbreaking productivity tool that leverages the power of large language models, user data, Microsoft Graph, and the web to drive unparalleled creativity and productivity. At the heart of this innovation is the Office AI team, which plays a crucial role in the development of Copilot experiences across M365 and an expanding list of partners across Microsoft. We own the infrastructure that enables complex orchestration of M365 Copilot workflows to put powerful AI capabilities at the user’s fingertips, as well as the chat user experience and horizontal skills, and extends across Word, Excel, PowerPoint, OneNote, and an expanding list of partners across Microsoft. As a Software Engineer on the Office AI Platform team, you’ll build and improve production systems that sit at the heart of Copilot, powering workflows used by millions of people every day. You’ll contribute to the platform components that orchestrate AI driven experiences across Microsoft 365, writing code that runs at global scale, is highly observable, and directly shapes customer experience. You’ll take on well scoped engineering work focused on reliability, performance, and platform evolution, collaborating closely with senior engineers to ship features, fix issues, and strengthen core systems. This role is a great fit for early career engineers who want to grow quickly while working on real systems at Microsoft scale.
Job Responsibility:
Build and ship features that are part of Office AI’s core platform, contributing code that runs in high‑scale, latency‑sensitive production systems
Work closely with senior engineers to implement well scoped improvements across services, APIs, and platform components
Learn how distributed systems behave in the real world by debugging live issues, analyzing telemetry, and understanding failure modes
Write clean, high‑quality code in C#, TypeScript, or JavaScript that meets Microsoft’s standards for reliability, security, and performance
Add logging, metrics, and alerts so your code is observable, debuggable, and resilient in production
Contribute tests and CI pipelines that help keep Copilot reliable as the platform evolves rapidly
Participate in code reviews, design discussions, and post‑incident learning to grow your engineering judgment
Gain hands‑on exposure to AI‑powered systems, platform authentication, and service‑to‑service communication patterns at Microsoft scale
Requirements:
Bachelor's Degree in Computer Science, or related technical discipline with proven experience coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python
OR equivalent experience
Basic understanding of data structures, algorithms, software engineering fundamentals and Distributed System Design
Nice to have:
Internship or project experience building backend services, APIs, or client‑server applications
Familiarity with testing practices, CI/CD pipelines, or cloud‑hosted services
Exposure to distributed systems, telemetry, or debugging production systems
Curiosity about AI‑powered applications, large‑scale platforms, or developer tooling
