Role overview
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.
- 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.
Application process
- You will be responsible for designing, building, maintaining and evolving the sync SDK powering Proton Drive's desktop applications.
- This includes not only building the application internals (managing and syncing local and remote state, performing cryptographic operations, etc) but also helping us to build resilient, scalable applications (graceful degradation; log and metrics streams free of personally identifiable information).
- You will be involved in the entire application lifecycle, but with a strong focus on the internals shared amongst our desktop applications, including Gitlab configuration, deployments, monitoring and alerting, and operational incident response.
- While this position is not a "full-stack" position, you will be expected to collaborate with backend engineers to drive any necessary changes and/or new features needed for the core of our desktop experience. What you will do:
- Be part of a small team working to bring a "privacy by default" solution to our Drive clients on Windows, macOS and Linux.
- Develop applications that delight a wide range of users, from layperson to technical, and gives confidence that their online privacy is in good hands - while getting the complexity of end-to-end encryption out of the way.
- Invest in test automation to improve the team's productivity and software delivery cadence.
- Think critically on how to divide problems into iterations of simpler, composable solutions.
Contacts
- 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.
