Principal Group Software Engineering Manager

In July 2026, Microsoft introduced Project Perception, an agentic security system that brings together coordinated red, blue, and green AI agents to help organizations defend against cyber threats at machine speed. As one of Microsoft's most significant investments in the future of security, Project Perception is helping redefine how AI can be used to identify, understand, and respond to an evolving threat landscape.

As a Principal Group Software Engineering Manager within the Agentic Security Org, you will play a critical leadership role in shaping and scaling this vision. You will lead the teams responsible for offensive and defensive AI agents, as well as the data science and applied machine learning capabilities that enable them to continuously learn, adapt, and improve. Working across engineering, security research, and data science disciplines, you will help build intelligent systems that are impactful, trustworthy, and designed with safety and responsible AI principles at their core.

Your charter is broad and highly visible: driving innovation across offensive security, defensive automation, and applied machine learning while fostering an inclusive, collaborative environment where diverse perspectives strengthen outcomes. You will be accountable for delivering agentic security capabilities that customers can rely on in real-world production environments and that help protect people, organizations, and digital ecosystems around the globe.

Microsoft's mission is to empower every person and every organization on the planet to achieve more. We come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Every 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.
