Job Description

Security represents the most critical priorities for our customers in a world awash in digital threats, regulatory scrutiny, and estate complexity. Microsoft Security aspires to make the world a safer place for all.

You’ll be working collaboratively with Engineering, Threat Intelligence, and Data Science teams to improve our defense-in-depth capabilities to thwart persistent threats and respond to customer escalations.

Together, we are redefining email and web security using the latest technology, unparalleled data and intelligence systems. Join us and make a difference in our mission to empower everyone to communicate with confidence and trust!

Microsoft’s mission is to empower every person and every organization on the planet to achieve more.
