OverviewSoftware 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 user privacy, security, and trust on the web.
As a principal engineer on the Web Platform Privacy team, you will help define how privacy and identity work on the modern web. Our team owns the browser capabilities that protect people from unwanted cross-site tracking and that enable safe, user-controlled sharing of identity - spanning areas such as tracking prevention, federated identity (FedCM), and digital credentials. You will help drive web standards, collaborate with the broader standards community, and deliver interoperable implementations that improve privacy and trust across Microsoft Edge and Chromium.
We are seeking engineers with solid systems thinking and a deep interest in user privacy, identity, and browser architecture. In this role, you will design and own core platform features that balance robust privacy protections with web compatibility and a great user and developer experience - with a focus on correctness, performance, and trust at web scale. You will thrive on ambiguous, cross-cutting problems where privacy, security, usability, and ecosystem impact intersect.
You will work on initiatives central to Edge's web platform strategy, collaborating with standards bodies (W3C / WHATWG / IETF), community and working groups (such as those focused on privacy and federated identity), other browser vendors, and internal teams to bring new capabilities to the platform. Success in this role requires depth in browser or runtime systems and end-to-end ownership from exploration and prototyping to 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.
