Company mission
To fight for a better internet that is secure and private by default.
Role
Who you are
- You have extensive experience building and shipping high-quality iOS applications
- You care deeply about product quality, usability, and delivering exceptional user experiences
- You have strong experience building maintainable, scalable, and testable mobile architectures
- You are comfortable working across large codebases and collaborating across multiple teams
- You have experience mentoring engineers and raising the technical bar within a team
- You have a strong understanding of performance, concurrency, and mobile memory management
- You are comfortable navigating ambiguity and contributing to product and technical discussions
- Experience with privacy, security, encryption, sync systems, or offline-first architectures is a strong plus
- Rust experience is a plus, but not required as we continue moving towards a platform-independent Rust logical core communicating with the iOS application via generic interfaces
What the job involves
- Based in our Barcelona office, you’ll join one of several high-impact product teams across Proton Pass, Proton Wallet/Payments, and Proton VPN, helping build privacy-first products used by millions around the world.
- From secure password management and identity protection to encrypted financial tools and internet freedom products that help users bypass censorship and surveillance, you’ll work on technically ambitious products with real-world impact.
- As a senior engineer, you’ll collaborate closely with product, design, and engineers across Proton to build and ship high-quality experiences on Apple platforms, helping define what “great” looks like for privacy-focused consumer products at scale
Our take
Proton is a Geneva-based startup founded by former CERN worker and internet privacy advocate Andy Yen. It provides internet users with encrypted webmail, calendar, drive, and VPN services.
Proton maintains its pro-privacy ethos using a Swiss VPN, protected by strict Swiss privacy laws. In essence, it has established a connection between the personal and the political, smartly utilising the country’s national laws to benefit people and organisations globally. Proton also funds charities and movements such as the World Wide Web Foundation and Netblocks, further cementing it as an influential NGO.
Perhaps Proton’s most important quality is its determination to maintain independence from advertisers and companies. Originally founded on donations, Proton has funded itself via grants rather than venture capital so that all of its customer's data is never at risk of being mined. One effect of this is that to keep up with the increasing competition in the data privacy sector, Proton has expanded its services to allow more cross-selling and simultaneously has more products to offer, such as drive and calendar privacy.
