Principal Software Engineer

Are you passionate about building large-scale, high-performance distributed systems that power the intelligent edge of the Internet? Do you thrive on solving complex technical challenges at global scale and enjoy working on systems that millions of customers depend on every single day?

The Azure Front Door (AFD) service is an Edge Distribution Platform that provides application delivery, acceleration, global load balancing, security, and intelligent routing for some of Microsoft’s most critical services—Office 365, Xbox, LinkedIn, Azure Services—as well as thousands of enterprise customers worldwide. We operate at Internet scale, handling millions of requests per second across thousands of servers globally.

The AFD Management Services team owns how customers configure and operate Azure Front Door—this includes the Resource Provider (RP), management APIs and SDKs, CLI/PowerShell tooling, and the Azure Portal experience. Our mission is to deliver a seamless, reliable, and secure management experience that empowers developers and operators to confidently manage their global networking workloads. Every configuration change can impact billions of requests, so resilience, safety, and developer experience are our obsessions.

As a Principal Software Engineer, you will be the technical leader who sets the bar for architecture, code quality, and operability. You’ll own critical management‑plane components and lead multi‑engineer efforts that ship new capabilities safely to a global fleet. Your work will directly shape how customers secure origins, roll out changes, validate configurations, and observe their edge traffic worldwide.

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.
