Nice to have: * Payment integrations (Adyen, Apple Pay, Google Pay). * Feature flag systems (e.g., LaunchDarkly). * Mobile analytics or error tracking (Sentry, Adobe Experience Platform, Quantum Metric). * CI/CD for mobile: GitHub Actions, Expo EAS, Fastlane, BrowserStack. * Internationalization (i18n) and multi-language app support. ## Description We're looking for an experienced mobile engineer to help build and improve the Subway app on iOS and Android - the app millions of guests use to order food, manage their loyalty rewards, find nearby restaurants, and check out with their preferred payment method. You'll work in a collaborative product team alongside designers, product managers, and other engineers, shipping features that are fast, reliable, and polished. App performance is a core priority: every change is expected to maintain or improve speed metrics we track rigorously., * Build and maintain app features across the full stack of the mobile experience - ordering, menu, cart, checkout, payments, loyalty, and store locator. * Write clean, well-tested TypeScript following our established coding standards, with automated checks (linting, formatting, architectural boundary rules) running on every commit. * Connect the app to backend services and third-party tools: our ordering API, authentication, payment processors, fraud detection, feature flags, and analytics. * Work with product managers, designers, and backend engineers to turn requirements into working software - joining sprint planning and reviews, implementing against Figma designs, aligning on API contracts. * Review code from teammates and incorporate review feedback on your own pull requests; all PRs go through CI checks and peer review before merging (no direct pushes to main). * Debug and fix issues on both iOS and Android using crash reporting tools, native logs, and device/simulator builds. * Write and maintain tests - unit, component, performance (we track render and time-to-interactive budgets), and end-to-end flows tested on real devices via BrowserStack. * Help keep our build and release pipelines healthy: automated builds, beta testing distributions, and production releases to the App Store and Google Play. * Document your work - code comments, architecture decision records, and notes in our project management system. * Participate in Agile ceremonies: standups, sprint planning, refinement, and retrospectives. * Stay current with the React Native ecosystem and contribute to team-wide improvements, including our ongoing migration to the React Native New Architecture (better performance and native integration). ## Related Videos - [Kotlin Multiplatform - True power of native code reuse](https://www.wearedevelopers.com/videos/4-kotlin-multiplatform-true-power-of-native-code-reuse) - [Boost Productivity with AI: Figma & Playwright MCP Workflows - Aris Markogiannakis](https://www.wearedevelopers.com/videos/1768-boost-productivity-with-ai-figma-playwright-mcp-workflows-aris-markogiannakis) - [Innovating Developer Tools with AI: Insights from GitHub Next](https://www.wearedevelopers.com/videos/1268-innovating-developer-tools-with-ai-insights-from-github-next) - [There's an app for that - on the role of cross platform development in the app development ecosystem](https://www.wearedevelopers.com/videos/278-there-s-an-app-for-that-on-the-role-of-cross-platform-development-in-the-app-development-ecosystem) - [Designing the Future of Human<>Agent Collaboration](https://www.wearedevelopers.com/videos/1447-designing-the-future-of-human-agent-collaboration) - [Making the switch from web to mobile development](https://www.wearedevelopers.com/videos/274-making-the-switch-from-web-to-mobile-development) ## Related Articles - [React Developer Salary [2023]](https://www.wearedevelopers.com/magazine/198-react-developer-salary-2023) - [16 Best Free React UI Libraries in 2025](https://www.wearedevelopers.com/magazine/148-16-best-free-react-ui-libraries-in-2025) - [Cross Platform Mobile Development Frameworks to Use in 2025](https://www.wearedevelopers.com/magazine/404-cross-platform-mobile-development-frameworks-to-use-in-2025) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Flutter Developer Salary [2023]](https://www.wearedevelopers.com/magazine/199-flutter-developer-salary-2023) - [How Much FAANG Companies Actually Pay Software Engineers in 2025](https://www.wearedevelopers.com/magazine/230-how-much-faang-companies-actually-pay-software-engineers-in-2025)
