Principal Security Engineer Manager

The Microsoft Offensive Research & Security Engineering (MORSE) team is looking for a learn-it-all security engineering manager that will help secure Microsoft products. The MORSE team is responsible for securing Microsoft's operating systems, including Windows, cloud computing platforms, and virtualization technologies. These solutions support the daily needs of over one billion customers worldwide. This team performs security design reviews, code reviews, and vulnerability research on key features of Windows and Azure to make sure they meet the highest possible security standards. Our engineering team builds mitigations, hardens operating systems, builds scalable bug detection systems, improves developer tools, and creates cutting edge vulnerability research capabilities. In this role, you will lead a team of security engineers focused on eliminating vulnerabilities at scale. Your team will design and develop new security mitigations, drive systematic reductions in entire classes of vulnerabilities, and partner with product teams to refactor and harden highrisk codebases across Microsoft operating systems. As a people manager, you will prioritize the growth and success of your team—coaching engineers, supporting career development, fostering a healthy and inclusive team culture, and advocating for both individual and collective impact. You will work closely with peer managers and technical leads to drive program execution, enable clear and continuous feedback loops, and help evolve processes that improve how MORSE operates and scales. The ideal candidate has experience managing platform security engineering teams, a strong foundation in operating system security fundamentals, hands on experience with native code (C/C++), and a track record of operating effectively in high ambiguity, high autonomy environments.
