The Identity Security (IDSEC) Breach Preventions team is responsible for preventing repeat security incidents across Microsoft’s Identity platform by building scalable, engineering driven security controls that eliminate entire classes of vulnerabilities before they can be exploited. Our team operates at the intersection of software engineering and security research to design and deploy platform level countermeasures across Microsoft’s Identity and Network Access (IDNA) services. We focus on proactively identifying authentication and authorization attack paths, translating breach learnings into reusable preventative mechanisms, and automating security enforcement across hundreds of production services. Our goal is to move beyond reactive vulnerability mitigation by harmonizing engineering and security systems to automate reusable protections across the identity technology stack. We are looking for a Senior Security Engineer to join our team.

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.
