Software engineers on the Microsoft AI Experiences - Edge Web Platform team build foundational technologies that shape how hundreds of millions of people experience the web and AI-powered computing. Edge operates at massive scale and extends beyond a traditional browser as a gateway to Microsoft's products and AI ecosystem. This role offers the opportunity to shape a widely used web platform by advancing its capabilities, performance, security, accessibility, and user experience.
As a principal engineer on the Edge Web Platform team, you will help define and deliver foundational browser technologies and web platform capabilities spanning areas such as networking and navigation; media and storage; rendering and layout; web APIs and the JavaScript engine; privacy, security, and identity; and developer and application platforms. You will help drive web standards, collaborate with the broader standards and open-source communities, and deliver interoperable implementations that improve the web across Microsoft Edge and Chromium.
You will work on initiatives central to Edge's web platform strategy, collaborating with standards bodies, open-source communities, other browser vendors, and teams across Microsoft to bring new capabilities to the platform. Success in this role requires depth in browser, runtime, or systems engineering; strong systems thinking; the ability to establish technical direction across organizational boundaries; and end-to-end ownership from exploration and prototyping through standardization and shipping.
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.
