Principal Security Engineer

The Microsoft Offensive Research & Security Engineering (MORSE) team is looking for a Principal Security Engineer to help secure Microsoft’s products and devices.

MORSE is responsible for securing Microsoft’s operating systems and platform technologies, cloud platforms, and virtualisation technologies that support the daily needs of over a billion customers worldwide.

In this role, you will work across the discovery and mitigation of security vulnerabilities — identifying weaknesses in systems, understanding their impact, and helping drive protections that improve the security of Microsoft platforms at scale. You will partner with engineers across Windows, Azure, and platform infrastructure to architect security solutions and influence the way systems are designed and built.

This role is well suited to engineers who enjoy deep systems work, solving complex problems, and delivering high impact security outcomes.
