Note: The job is a remote job and is open to candidates in USA. Zephyr Cloud is seeking a Senior Mobile Engineer to lead the mobile experience for their AI Platform. The role involves building a React Native application for iOS and Android, owning the mobile architecture, and contributing to the mobile infrastructure of Zephyr Cloud.

Responsibilities

• Own the end-to-end mobile architecture, including state management, navigation, native integrations, APIs, and real-time communication
• Define how much of the shared React frontend should be reused versus rebuilt for mobile
• Partner with design and engineering to create a native mobile experience that feels at home on both iOS and Android
• Shape the future of mobile AI-assisted software development
• Contribute to the mobile capabilities of Zephyr Cloud, our deployment platform, with a focus on the infrastructure that enables seamless mobile delivery
• Build and maintain our React Native OTA update infrastructure using Module Federation 2.0 Runtime API, supporting Metro-based OTA workflows, and enhancing the developer experience for mobile deployments on Zephyr Cloud

Skills

• 5+ years of mobile engineering, with deep React Native experience
• Led a React Native app from greenfield to production, or owned a significant migration or re-architecture end-to-end
• Shipped and maintained apps in the App Store and Play Store — you own releases, code signing, provisioning, and store review
• Set architecture and patterns for a mobile codebase others build on, and comfortable making and defending technical decisions
• Strong cross-platform skills across iOS and Android — comfortable in the native layer when you need to be
• A sharp eye for performance and native UX — you partner with design to make mobile feel native, not ported
• Hands-on experience with Metro and/or Re.Pack (Webpack/Rspack-based React Native bundling)
• Experience with Expo (managed and/or bare workflow)
• Familiarity with React Native OTA mechanisms (Expo Updates, Hot Updater, or similar)
• Comfortable owning mobile CI/CD, release automation, and the testing that keeps a shipping app stable
• Strong async communication — we're fully remote and globally distributed
• Micro-frontend architecture in React Native contexts
• Module Federation (Webpack / Re.Pack-based)
• Contributing to or maintaining a developer-tooling or SDK product
• Exposure to Rust or native module development (our backend is Rust/Tauri)
