Microsoft 365 and Copilot run on Substrate & Work IQ (SWIQ)—the trusted data and intelligence platform powering service health, operational excellence, business insights, and AI-driven decision making across Microsoft's largest cloud services. As Microsoft 365 and Copilot continue to grow at unprecedented scale, SWIQ provides the foundational intelligence that connects product experiences, infrastructure, operations, and business outcomes, enabling teams to build, operate, and innovate with confidence.
The SWIQ Performance Team is hiring a Principal Software Engineer to define and drive the technical strategy for Copilot and Microsoft 365 Cost of Goods Sold (COGS) intelligence. You will build the trusted platform that connects product usage, service dependencies, infrastructure consumption, operational telemetry, and Finance-aligned cost models into a unified and scalable economics foundation. This platform powers critical business decisions across engineering, capacity planning, product strategy, and finance, helping Microsoft optimize investments while accelerating innovation.
As a Principal Engineer, you will lead the design of durable architectures that transform complex cross-organizational challenges into trusted platforms, reusable intelligence, and measurable business impact. You will work across rapidly evolving Copilot experiences—including agents, enterprise productivity, collaboration, and emerging AI workloads—to make the relationships between cost, quality, reliability, efficiency, and customer value transparent and actionable.
A key expectation of this role is to drive AI-native transformation. You will reimagine how economics systems are built and operated by leveraging agents, intelligent automation, and machine reasoning to discover cost drivers, identify attribution gaps, evaluate optimization opportunities, recommend actions, learn from outcomes, and continuously improve decision quality. Your work will help shift operational and business decision making from manual analysis toward intelligent, autonomous systems that scale with the future of Microsoft 365 and Copilot.
