Anti-Abuse Engineer

Job description

ProtonMail was started by scientists and engineers from CERN in 2013 to make end-to-end encrypted email as easy to use as Gmail. Since then, we have grown to become the world's premier secure email service with over 10 million users and a profitable business model. We are rapidly scaling our talented teams to improve our core email product as well as to build an entire suite of web services that safeguards privacy in the digital age.


While the open nature of email is great for interoperability, accessibility and freedom from centralized control, it also creates challenging spam and abuse problems. For instance, a significant percentage of incoming emails to ProtonMail users are spam, some of which are dangerous phishing attacks. Also, as a free email service open to all, ProtonMail inevitably attracts signups from bad actors who abuse our excellent email delivery and reputation.

  • Fight spam, including internal end-to-end encrypted emails
  • Protect users against various attacks and prevent compromised accounts
  • Train abuse desk team to effectively respond to abuse and to help affected users
  • Automate, deploy, monitor, and troubleshoot critical anti-abuse systems
