AI agents are transforming how organizations automate workflows, make decisions, and scale productivity. As agents increasingly reason, plan, and execute actions autonomously, they need secure, reliable, and governed connectivity to enterprise data, tools, and services.
Agent 365 is Microsoft’s unified control plane for AI agents, providing capabilities for agent registry, lifecycle management, access governance, observability, interoperability, and security. The WorkIQ-Infra team builds the foundational connectors and connection-management services that power Microsoft 365 Copilot, Agent 365, and Power Platform–based agents, workflows, and applications.
As a Principal Software Engineer, you will help shape and build the Agent Connectivity Platform, enabling agents to discover, authenticate to, and interact with enterprise and third-party systems. You will drive architecture, deliver production-quality code, and solve complex distributed-systems challenges across connectors, connection lifecycle management, authentication, and secure tool invocation.
This is a hands-on individual contributor role with technical influence across teams. Your work will directly impact how agents connect and operate across organizational boundaries—securely, reliably, and at global Microsoft scale.
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.
