In this world where we need to assume all networks are compromised, would you like to craft the defenses that protect our customers. We would like to provide our customers with reliable and secure connectivity whether it is a student, an artist or an enterprise worker, and enable them to be at their productive best. We are a fun, inclusive team that keeps the customers' needs top of mind. You will be part of the organization which delivers code to Azure, Windows Server and Windows Client.
