As Microsoft continues to push the boundaries of AI, we are on the lookout for passionate individuals to work with us on the most interesting and challenging AI questions of our time. Our vision is bold and broad — to build systems that have true artificial intelligence across agents, applications, services, and infrastructure. It’s also inclusive: we aim to make AI accessible to all — consumers, businesses, developers — so that everyone can realize its benefits. Join us in building the foundation for the next generation of AI.

The Platform Engineering team is responsible for designing and optimizing AI Agents that can reason, plan, and take action autonomously. we build robust orchestration layers that coordinate complex multi-model and multi-service workflows with reliability and scale. We push the boundaries of inference performance, driving low-latency, high-quality model execution across production workloads. As a Member of Technical Staff, Platform Tools, you'll design and deliver the primitives that power Copilot and other AI-powered experiences. These building blocks form the backbone of secure, scalable, and reliable workflows that product teams use to craft robust and seamless user experiences. From tool orchestration to performance optimization, you'll deliver fast, secure, and dependable execution that turns Copilot into a true productivity engine.

Your work will make it possible for agents to call APIs, services, and workflows securely, efficiently, and with high success rates - ensuring Copilot doesn't just answer questions but gets things done.

Ideal candidates have backend or ML systems expertise who thrive at the intersection of product and inference. You take ownership, tackle hard problems, and build the connective systems that make AI products fast, reliable, and scalable- collaborating with teams to deliver high-impact platforms that power real-world workflows.

Microsoft’s mission is to empower every person and every organization on the planet to achieve more. As employees we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.
