Join Proton and build a better internet where privacy is the default

At Proton, we believe that privacy is a fundamental human right and the cornerstone of democracy. Since our inception in 2014, founded by a team of scientists from CERN, we have dedicated ourselves to providing free and open-source technology to millions worldwide, ensuring access to privacy, security, and freedom online.

Our journey began with Proton Mail, the largest secure email service globally, and has since expanded to include Proton VPN, Proton Calendar, Proton Drive, and Proton Pass. These tools empower individuals and organizations to take control of their personal data, break away from Big Tech’s invasive practices, and defeat censorship. Our work impacts hundreds of millions of lives, from activists on the front lines defending freedom to leaders in governments protecting sensitive information. In some cases, Proton’s services have even been instrumental in saving lives by enabling secure and private communications in high-risk situations.

Proton today supports over 100 million user accounts with a growing team of over 500 people from over 50 different countries, from the world's top companies and universities. We value intelligence, learning potential, and ambition in our hiring process. Adaptability is key as we navigate uncharted territories and redefine how business is conducted online. We believe smaller teams of exceptional talent will always prevail over larger teams with lower talent density. Proton has become profitable and reached scale without relying upon VC funding, largely due to superior talent that allows us to do things faster, more creatively, and more efficiently.

We have a global mindset and big ambitions but remain a start-up at heart. We value empowerment and flexibility and keep our structure flat to keep moving fast and avoid unnecessary politics.

The team:

The MSA department is a highly multi-disciplinary group started in 2019 to tackle difficult mail delivery, spam and abuse problems. We built sophisticated systems from scratch that combine human intelligence and machine learning to make tens of millions of real-time or asynchronous decisions each day. As of 2024, our three areas of focus are 1) mail delivery and spam, 2) abuse and account security, and 3) site reliability of Proton. Over the past years, our custom systems have reduced spam filter misclassifications by over 50%, blocked millions of abusive bulk signups, protected hundreds of thousands of users from account compromise by attackers, and mitigated hundreds of DDoS attacks. In order to move fast with limited resources, we are organized into autonomous teams responsible for the whole system, with expertise across infrastructure, data storage, backend, frontend, machine learning, security, operational excellence, and customer support. In 5 years time, we grew from 2 engineers to over 40 engineers, analysts, and customer support agents, spread across 3 continents for 24/7 coverage. We are looking for humble, mission-driven, systems-thinking people who want to make a big impact in a startup environment.

We are looking for enthusiastic tech-savvy individuals to join our Technical Customer Support team in the MSA department.

Tech Stack and Tools:

Zendesk, Jira, Confluence, Jupyter, Slack, and use of Proton's products internally: mail, drive, wallet, pass, VPN, etc. Our Technical Support team actively communicate with other third-party services to troubleshoot any potential mail delivery or registration issues. 

Impact Opportunities:

While listening to customer concerns, suggestions, and preferences, Technical Support not only extends far beyond resolving customer inquires, they are often required to troubleshoot issues on their own, which results in coming up with valuable data that can be used to improve products, services, and processes. This loop between user feedback and self-development helps businesses make informed decisions and drive continuous improvement, ultimately leading to increased customer satisfaction and business growth.

Technical Support team are also in charge of supervising the account security of our customers, promising the protection of all data, keeping all information private and secured. As our slogan states, “without privacy, there can be no freedom of speech, and without freedom of speech, there can be no democracy”, the Technical Support team are here to ensure Proton remains the trusted choice for an encrypted communication platform.
