Software Engineer II

AI is transforming productivity in profound ways. As the new home of Office productivity, the M365 Copilot App is at the forefront of this transformation. It is one of the fastest growing products at Microsoft, and the primary means through which most M365 users experience the power of Copilot – be it Chat, Search, or Agents. M365 Copilot App is a multi-platform product, built for consumer-grade experiences and enterprise-grade trust. Our team is responsible for all aspects of engineering for this ecosystem of applications and services. As a Software Engineer on the team, you will be responsible for designing, building and maintaining the Copilot application across Windows, Mac, and Web platforms. You will participate in architectural decisions and contribute hands-on code to advance the state of the art and build best-in-class applications, balancing innovation with platform stability. You will work closely with other engineers to take ideas through design, implementation, validation, and release. You will write secure, reliable, scalable, and high-performance code as well as automation to test it and telemetry to measure its behavior in production. You will work in a fast paced, highly collaborative environment to design, prototype, implement, and ship features. You will partner across multiple product and platform teams in Microsoft and define reusable architectural patterns and best practices that enable consistent, intelligent, and high-performing user experiences at scale. You will mentor engineers and foster a culture of technical excellence through best practices in architecture, performance profiling, and cross-platform design systems. You will provide engineering leadership to others in the team in taking on the engineering and technical challenges inherent in building and delivering a consumer-grade application that powers cross-platform AI experiences.
