Senior React Native Engineer

About the role

We are looking for a Senior React Native Engineer to build and maintain consumer mobile app features for a global QSR brand, spanning ordering, menu, cart, checkout, payments, and loyalty across iOS and Android. You will write clean TypeScript, integrate backend ordering and authentication APIs, maintain automated tests including end-to-end flows on real devices via BrowserStack, and contribute to the ongoing migration to React Native New Architecture. The role follows collaborative Agile practices with peer code review on every pull request.

What you will do

• 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 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: 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 pull requests; all PRs go through CI checks and peer review before merging;
• 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, and end-to-end flows tested on real devices via BrowserStack;
• Help keep build and release pipelines healthy: automated builds, beta testing distributions, and production releases to the App Store and Google Play;
• Document work — code comments, architecture decision records, and notes in the 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 the ongoing migration to the React Native New Architecture.

Must haves

• 4+ years of professional software engineering experience;
• Strong commercial experience building cross-platform mobile apps with React Native and TypeScript;
• Solid understanding of React Native architecture: state management (Redux), navigation, performance optimization, and local storage;
• Experience calling REST APIs and working with token-based authentication flows;
• Familiarity with the native side of React Native — iOS (Swift/Objective-C) and Android (Kotlin/Java) builds, native modules — or genuine enthusiasm to learn;
• Practical experience with mobile testing: unit tests, component tests, and end-to-end flows;
• Experience shipping apps to the App Store and/or Google Play;
• Clear communicator who works well in a collaborative, cross-functional team;
• Upper-intermediate English level.

Nice to haves

• 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;
• Privacy and consent frameworks (e.g., OneTrust);
• SSL/certificate pinning for mobile API security.
