We are looking for a Software Engineer II to join one of our Adaptive Email Data Loss Prevention (AEDLP) teams. The team owns Proofpoint’s Microsoft 365 add-in (currently for Outlook), which helps organisations stop sensitive data leaving through email.

• Improve the user experience of our add-in in Outlook (desktop and Outlook on the web) on Windows and Mac 

• Help harden the “Human Security Layer” 

• Ship code to production continuously via CI/CD 

• Handle sensitive data with care, and build with security in mind 

• Work with senior and staff engineers on complex problems, and independently on simpler ones
