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. Tired of blending into the crowd? Join us and do work you can

truly be proud of. Check our social media pages to learn more about us: Twitter, Reddit, Instagram.

The role:

You will be responsible for designing, building, maintaining and evolving Proton applications on Windows. 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 a resilient, scalable application (graceful degradation; log and metrics streams free of personally

identifiable information). You will be involved in the entire application lifecycle, 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 Windows

experience.

What you will do:

Be part of a small team working to bring a "privacy by default" solution to our clients on Windows.
Develop an application that delights 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 testing and automation to improve the team's productivity and software delivery cadence.
Think critically on how to divide problems into iterations of simpler, composable solutions. Re-evaluate the minimum scope as

necessary to meet objectives on-time.

Insist on high standards for application monitoring and alerting, in order to ensure a smooth customer experience at all times.

We we are looking for:

Strong experience in .NET development
Strong experience building and maintaining Desktop Windows applications
Strong experience with concurrent multi-threaded programming
Working knowledge of file systems
Working knowledge of Git
Bachelor's or master’s degree in a relevant field of study
Experience with owning and maintaining large software components
Experience with gradual rollouts and metrics/monitoring/alerting frameworks

Even if you don’t meet all the requirements listed above, but feel you could still be a great fit, please still apply.

What We Offer

Office First: Collaboration is easier and more effective in person, which is why we have offices in Geneva, Zurich, Prague,

Barcelona, Paris, London, Vilnius, Skopje, and Taipei. You can also enjoy working from home up to 30% of the time, while

disposal to achieve your goals.

policies, and wellness programs.

community input. To this day, Proton’s only source of revenue is user subscriptions. Over 100 million people trust and support

Proton, and we put our users and community first in everything we do. Read more about our impact here.
