A rapidly growing Italy-based tech startup operating in the performance marketing and rewarded advertising spaceis looking for a skilled React Native Engineer to help build and scale the mobile app for iOS and Android. In this role, you will own the end-to-end implementation of key features for a platform serving millions of users globally. You will be writing robust, performant TypeScript code and collaborating with product teams to solve complex challenges. This is a high-impact role where you will work with a modern React Native stack, aiming to keep our app fast, reliable, and easy to maintain.
You will focus on: * Feature Delivery: Building high-performance, user-centric mobile features for iOS and Android. * Code Quality: Writing clean, testable TypeScript code and actively participating in code reviews. * Performance: Identifying bottlenecks (app size, re-renders, startup time) and implementing fixes. * Collaboration: Working directly with Backend, QA, and Product teams to clarify requirements and deliver seamless UX. * Growth: Contributing to architectural discussions and learning best practices from senior engineers.
Key Responsibilities: * Design & Implementation * Develop and maintain cross-platform applications using React Native and TypeScript. * Build reusable UI components and performant lists (FlashList/FlatList) that adhere to design specs. * Integrate mobile apps with backend services via RESTful APIs and WebSockets. * Debug platform-specific issues using Xcode and Android Studio, writing native modules (Swift/Kotlin) when necessary. * Engineering Standards * Contribute to the codebase’s health by fixing technical debt and improving test coverage. * Participate in architectural discussions, offering input on state management and navigation patterns. * Review peer code to ensure it meets our standards for readability and maintainability. * Performance & Reliability * Monitor production crashes (using tools like Sentry/Crashlytics) and proactively fix stability issues. * Optimize app performance, focusing on frame rates, memory usage, and battery consumption. * Assist in maintaining CI/CD pipelines to ensure smooth releases to the App Store and Google Play.
Requirements: * 3+ years of professional software engineering experience, with at least 2 years focused on React Native. * Strong proficiency in TypeScript and the React Native ecosystem (CLI, Hermes, debugging tools). * Good understanding of the iOS and Android build systems (Gradle, Pods, signing/provisioning). * Ability to read native code (Swift/Kotlin) to debug issues. * Familiarity with modern patterns (Functional Components, Hooks) and state management (Redux Toolkit, Zustand, or TanStack Query). * Experience writing unit tests (Jest) and familiarity with E2E testing concepts. * Ability to explain technical constraints to non-technical stakeholders clearly. * English: B2, written and spoken; ability to work in a team and communicate clearly in English.
Nice to Have: * Experience launching and maintaining a B2C app with 100k+ MAU. * Hands-on experience writing Native Modules or JSI/TurboModules from scratch. * Familiarity with mobile analytics (Segment, Amplitude) and A/B testing implementation. * Experience with Maestro/Appium for automation. * Knowledge of backend fundamentals (Node.js) to debug API integrations effectively. * Experience with Web development (ReactJS, NextJS)
We Offer: * Scale: Your code will impact millions of users globally, where performance optimizations translate to immediate value. * Modern Stack: Work with the latest React Native tools without being bogged down by legacy spaghetti code. * Growth Culture: A collaborative environment with code reviews and knowledge sharing — we value the best idea, regardless of title. * Impact: A fast-paced environment where you can see your features go live quickly.
