Job description

Our mission is to defend human rights and democracy through building software that is essential for digital freedom and privacy protection for all Internet users.

ProtonMail was founded in 2014 by a group of scientists who met at the European Organization for Nuclear Research (CERN).

And since its inception, the company has grown at a fast pace and today has over 26 million users. Our principal product, ProtonMail , is the world’s largest secure email service.

Our team is diverse and dynamic, representing over 30 different nationalities, with offices in Geneva, Zurich, Prague, Vilnius, Skopje, San Francisco, and Taipei.

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.

You will join a growing abuse team to build and operate sophisticated anti-spam and anti-abuse systems. This team contains a mix of senior software engineers and devops / site reliability engineers.

Your work will directly improve the user experience and digital security of millions

of people around the world. You should have extensive experience designing and developing real-time analysis and prediction systems.

What you will do :

  • Improve our abuse detection and prevention systems (bulk signups, compromised accounts)
  • 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
  • Job requirements

  • Software engineering experience with production systems (Python, PHP, JavaScript)
  • Experienced with data analysis and machine learning (anomaly detection, time series, clustering, NLP)
  • Bonus : worked with big data storage and web services (MySQL, Redis, Kafka, Elasticsearch)
  • Why you should join Proton :

  • We work on interesting, challenging problems every day. There is never a dull moment.
  • Our startup culture means everyone’s opinion matters. You can have a significant impact.
  • Our rapid growth means there are many opportunities for advancement.
  • The chance to do something meaningful. Proton products protect dissidents, journalists, and activists. Our work saves lives.
  • Be part of something bigger. Millions of people and businesses around the world have embraced our idea of an Internet where privacy and security are the default.
  • Join the privacy revolution that is changing the world.

    ProtonMail is using Recruitee recruitment platform for more effective hiring and better candidate experience. Your data will be kept confidential and not shared with any third parties.
