Front-End Engineer - Payments

Job description

A better internet, where privacy is the default, is possible. Building this better internet might seem daunting or even unthinkable, but at Proton, this is what we do every day.

Proton was founded in 2014 by a group of scientists who met at the European Organization for Nuclear Research (CERN). Our first product, Proton Mail, is now the world’s largest encrypted email service. Subsequent Proton products, such as Proton VPN, Proton Calendar, and Proton Drive, give our users full control over how and with whom their data is shared.

Today, Proton makes privacy universally accessible. Journalists from outlets like The Guardian and The New York Times, some of the world’s largest organizations, and people in more than 180 countries have signed up for over 70 million accounts. Our diverse and dynamic team is made up of more than 400 members representing over 40 different nationalities. While we are based in Geneva, Switzerland, we have offices in Zurich, Prague, London, Vilnius, Skopje, Taipei, and many more employees working remotely around the world.

Join one of Europe’s fastest-growing companies to help us solve challenging problems and build new products that will reach hundreds of millions of people. We want to create more than just one of the world’s most impactful tech companies; we want to create a new internet that serves the interests of all people. We need you, your voice, your ideas, and your ambition to make it happen.


Purpose of the role

The goal of the Payments team is to integrate online payments using dedicated providers and client libraries to facilitate the operations of our business. The technical implementation of payments is shared across all Proton products and its smooth operation is a key criterion in our success.

As a first Front-end Engineer in the team, you will be in charge of bringing the Payments at Proton together and creating more streamlined, centralized and efficient payment processing. We do not have front-end integration with payment providers but use server-side processing instead (due to security reasons). In the beginning, we expect you to work on erasing the technical debt and the next step should be to create a set of core modules that all of our clients will integrate. There is a huge opportunity for an ambitious SW Engineer to work on a greenfield project and potentially to also build the team of Front-end Engineers within the Payments team.


What you will do

  • Build scalable, reliable, and secure web applications
  • Build complex front-end logic to handle encryption and decryption, caching, synchronization, performance optimization and third-party provider integration (such as payments)
  • Write software to improve web app reliability (unit tests, automated testing)
  • Find elegant solutions to usability problems
  • Initiate new web technologies that will make Proton better
  • Work on product integration with payments platforms

Job requirements
