You will own the Android and iOS mobile domain end-to-end: a consumer VPN with 10M+ installs, 1,000+ servers in 45+ countries, and users in some of the most restrictive network environments in the world. </p> <p>This is an ownership-heavy role: you'll inherit existing mobile codebases, understand how the apps interact with the VPN networking stack, close knowledge gaps from the acquired team, improve engineering quality and release processes, and ship product improvements that directly impact users and the business.</p> <p>The apps sit on top of a custom Go networking engine (Shadowsocks / WireGuard) delivered as a native library, plus OpenVPN via TunnelKit on iOS, and you will be the person who makes that engine feel fast, reliable, and effortless to users. We are a user-facing product-led team, and we are looking for someone who is passionate about building private, secure products that people depend on every day.</p> <p>You’ll work closely with the backend engineer, DevOps/network engineer, product managers, designers, marketing, operations, and several stakeholders to define and execute according to our strategic roadmap to accelerate our future growth.</p> <p><strong>Who You Are and What You’ll Do</strong></p> <ul> <li>You are passionate about giving people private, secure, and unrestricted access to the internet. You care about your users and the trust they place in the product.</li> <li>You’re an expert in smartphone technology and love mobile application software, equally comfortable shipping on Android and iOS, and you are not afraid to go below the app layer into VPN tunnels, network extensions, and platform APIs.</li> <li>You know how to integrate and debug native libraries (.aar / .framework) written in other languages, and you don't need to be a Go expert, but you should be comfortable reading Go and debugging across the mobile/native-library boundary when investigating VPN issues.</li> <li>You enjoy inheriting an existing product, reading unfamiliar code, and reverse-engineering how things work, then making them better with tests, documentation, and refactoring.</li> <li>You embrace agentic AI as a force multiplier: you use AI coding agents to plan, implement, test, and review work, and you know when to trust them and when to verify.</li> <li>You value working closely with Product Management, learning directly from users about what matters to them, and developing solutions that they love.</li> <li>You care deeply about the impact of your work, and measure success by the value added to users’ lives: connection success rate, time-to-connect, crash-free sessions, and subscription conversion.</li> <li>You’re excited to write high-quality, maintainable, and well-tested code that you deliver. You are eager to find minimal ways to test hypotheses and validate feasibility.</li> <li>You’re a strong advocate for unit/integration testing and passionate about automated testing and continuously shipping to production on both app stores, replacing day-long manual regression with automation.</li> <li>You are security-minded: secure storage of tokens and keys (Keychain, EncryptedSharedPreferences), certificate handling, and user privacy are part of everyday engineering, not an afterthought.</li> </ul> <p><strong>What You Bring to the Team</strong></p> <p><strong>Must Have:</strong></p> <ul> <li>5+ years of professional senior mobile engineering experience in an agile environment delivering native applications to end-users on <strong>both Android and iOS</strong>, with hands-on production experience using:</li> <li>Android: Kotlin (and Java), Jetpack Compose and XML views (including migrating legacy XML to Compose), Coroutines, Flow, Koin, Dagger/Hilt, Retrofit, Room, WorkM
