Senior Android Software Engineer - Geneva
About The Position
Based in our Geneva office, you’ll join one of several high-impact product teams across Inbox (Proton Mail and Calendar), Proton Drive, Proton VPN, Lumo, and Meet, helping build privacy-first products used by millions around the world. From secure communication and encrypted cloud storage to privacy-preserving AI experiences and next-generation online collaboration tools, 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 Android experiences using Kotlin, Jetpack Compose, and an increasingly shared Rust core, helping define what “great” looks like for privacy-focused consumer products at scale.
Requirements
- Extensive experience building and shipping high-quality Android applications using Kotlin.
- Strong experience with Jetpack Compose and modern Android development practices.
- Care deeply about product quality, usability, and delivering exceptional user experiences.
- Strong experience building maintainable, scalable, and testable mobile architectures.
- Comfortable working across large codebases and collaborating across multiple teams.
- Strong understanding of performance, concurrency, multithreading, and mobile memory management.
- Understand mobile scalability considerations, including caching, network usage, responsiveness, and offline behaviour.
- Comfortable navigating ambiguity and contributing to product and technical discussions.
Nice To Haves
- 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 that communicates with our Android applications through generic interfaces.
Responsibilities
- Build and ship high-quality Android experiences using Kotlin and Jetpack Compose.
- Collaborate closely with product, design, and engineers across Proton.
- Define what “great” looks like for privacy-focused consumer products at scale.
- Take end-to-end ownership of features, from scoping and technical design through to delivery and iteration.
- Mentor engineers and raise the technical bar within a team.
