Job Description

The Identity security investigations team mission is to eliminate fraudulent accounts and prevent account compromise across all of Microsoft's Identity systems - consumer and enterprise, on any device and service.

Identity is the new control plane: all Microsoft services rely on Azure Active Directory and Microsoft Account to authenticate their users, and our goal is to keep all users safe. Every single day, our detection systems and machine learning algorithms evaluate and risk score more than 10 billion logins for more than 700 million users, stopping more than 30 million account compromises every day and millions of fraudulent account sign-ups. Users on Office 365, Xbox, OneDrive, Outlook, Azure, and at millions of enterprise desks around the world rely on us to keep their identities - and all the services and assets they allow access to - safe from cyber criminals.

We are looking for a talented individual to join our team who is passionate about data and security. Your job would entail diving through mountains of data and extracting insights to help us understand the ever-changing environment of identity compromise and abuse. Take a blank canvas made of terabytes of information and create smart algorithms that can detect the bad actors trying to sneak through the holes while maximizing the good users' productivity and usability.

Do you love big data and the challenges it entails? Do you like the idea of applying your technical skills to protect millions of Microsoft customers from malicious hackers? Would you like be part of team of smart, talented and mission driven people? Then this job is for you!
