Senior + Principal Software Engineers- Front End Applied AI for Microsoft Threat Protection (MTP)

The Microsoft Security Organization is building the next generation of security solutions by rethinking how security work is done from the ground up. The AI for Security (AI4S) team within the Microsoft Threat Protection (MTP) Org is pioneering a new paradigm: leveraging frontier AI models, security specific tooling, knowledge graphs, and deep context engineering to transform how defenders detect, investigate, and respond to threats at global scale. This is a fast paced, highly interdisciplinary environment focused on real world security outcomes. We are looking for Software Engineers (Senior and Principal levels) to help us build intelligent security systems that meaningfully reduce defender toil, improve precision and speed, and unlock entirely new security workflows that were previously impossible. As AI transforms how security operations are performed, this role will play a critical part in designing and building AI native user experiences that integrate reasoning, action, and feedback into how defenders interact with protection systems at global scale. You will contribute directly to creating world class AI powered security solutions used by millions of customers and security operators worldwide.
