Overview
The Product
Microsoft is leading the AI transformation. For the first time, organizations can leverage digital intelligence on demand to improve business outcomes and empower employees. Agents are at the center of this transformation—operating autonomously, collaborating with humans and other agents, supporting decisions, and spanning every business process.
The Copilot, Agents, and Platform (CAP) organization powers mission-critical Microsoft 365 and Dynamics 365 services, including BizChat, Work IQ, Agent 365, and the agent runtime for the next era of work. Together, we are building the platform that will power Microsoft's AI experiences for decades to come.
The Team
We are the M365 Core AI Inferencing Engineering team within CAP. Every major technology shift—from PCs to mobile and from on-premises to cloud—has fundamentally changed how products are built. AI is driving the next transformation, and GPU management has become critical infrastructure for this new era.
Our mission is to build and operate mission-critical, hyperscale, high-performance, cost-efficient, and compliant AI infrastructure that powers Microsoft's Large Language Model (LLM) services across Microsoft 365, Business & Industry Copilot, and other AI-powered products.
We are a growing team of software engineers, architects, applied scientists, and product managers from diverse backgrounds and experiences. We collaborate across Microsoft to solve challenging problems at scale and help teams deliver innovative AI experiences. We embrace AI in every aspect of our work and are driven by customer focus, technical excellence, creativity, teamwork, accountability, agility, and continuous learning.
The Candidate
We are looking for a Principal Software Engineer to help build the future of AI infrastructure at Microsoft. This is an opportunity to work on cutting-edge AI technologies at a scale and impact that is difficult to find anywhere else.
You will partner with teams across CAP and Microsoft to build the AI inferencing platform that enables engineers and applied scientists to rapidly develop AI-powered innovations using the latest models and technologies in a compliant, reliable, and cost-efficient manner.
Are you passionate about shaping the AI-first era? Do you enjoy solving complex technical challenges that impact millions of users? Do you thrive in a fast-paced environment where engineers take end-to-end ownership and collaborate closely to deliver results?
Join us and help build the AI inferencing platform that enables Microsoft's engineers and data scientists to do their best work while powering the next generation of AI experiences.
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.
