Job description
from Microsoft careersSoftware engineers on the 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 a 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 performance and user experience.
As a principal engineer on the Rendering team, you will shape the core primitives of the web platform - advancing DOM, HTML, and emerging web APIs. You will help drive web standards, collaborate with the broader standards community, and deliver interoperable implementations that improve browsing across Microsoft Edge and Chromium.
We are seeking engineers with solid systems thinking and deep interest in browser architecture, especially DOM tree construction and mutation, eventing, editing and form controls, selection and ranges, and accessibility semantics. In this role, you will design and own core platform features that shape how web content is represented, and experienced by millions of customers daily, with a focus on correctness, performance, and compatibility at web scale.
