Software Engineer II

** Overview*
* The Edge browser is a core strategic product and key entry point to Microsoft's new AI ecosystem, serving hundreds of millions of users daily. As the hypercompetitive AI browser ecosystem evolves, the Edge team is focused on continuing to lead.

Over the last several years, we've learned that the future of growth lies in combining massive reach with experiences that feel uniquely relevant to each user and their intent. Advances in client-side AI, reinforcement learning, and large language models have created a rare opportunity to reimagine personalization from the ground up. Realizing this vision requires pioneering new ways of integrating software engineering and data science-bridging the gap between signals and intelligence, experimentation and learning, design and distribution.

We're looking for an exceptional Software Engineer to join the Edge Growth Deep Personalization team and help build the foundation for a new era of AI-driven experiences that delight hundreds of millions of users 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.  

Starting January 26, 2026, Microsoft AI (MAI) employees who live within a 50- mile commute of a designated Microsoft office in the U.S. or 25-mile commute of a non-U.S., country-specific location are expected to work from the office at least four days per week. This expectation is subject to local law and may vary by jurisdiction.
