We deliver Contact Center AI as a highly available, enterprise-grade service that integrates cleanly with Azure and a broad ecosystem of first- and third-party products, enabling any surface to embed rich contact center experiences and advanced AI capabilities out of the box. We transform Microsoft’s advances in foundation models, multimodal systems, and AI agents into production-ready capabilities that help customers resolve complex needs with speed, consistency, and trust. Our mission is to deliver a world-class agentic platform where Copilot agents can reason, plan, act, collaborate with other agents, and transition seamlessly to human experts—turning frontier AI into dependable customer outcomes on a global scale.Our charter spans the full Microsoft Copilot Studio (MCS) runtime: intelligent agent authoring, orchestration, and invocation; secure tool and connector execution; knowledge grounding and retrieval; and a dynamic evaluation system that continuously measures quality as agents, models, data, and customer behaviors evolve. We use targeted evaluations, and drift detection to identify regressions early, understand their causes, and iterate rapidly—creating a closed learning loop that improves accuracy, resilience, and consistency over time.As a Software Engineer II on the team, you will design, build, and operate the features and services at the heart of this platform - writing production-grade code and delivering well-scoped components across the agentic stack, from real-time voice and orchestration to Copilot agents, tool invocation, and the Copilot Studio runtime that brings them to life. You will own the delivery of features end to end with growing independence, partner closely with senior engineers on design, and deepen your technical breadth across the stack. We are an AI-first organization: we rethink every workflow in an agentic way, innovate quickly, and collaborate closely with our partners and customers in an agile, fast-paced, high-energy environment. If this opportunity excites you, come and talk to us!Microsoft’s mission is to empower every person and every organization on the planet to achieve more.
