About The Role

We are looking for a skilled React Native Engineer to help build and scale Scrambly's mobile app for iOS and Android. In this role, you will own the end-to-end implementation of key features for a high-traffic platform serving millions of users globally. You will be responsible for translating product requirements into robust software, ensuring that our mobile experience remains user-centric and competitive.

Your primary focus will be on writing performant TypeScript code within a modern React Native stack. You will play a crucial role in maintaining app stability, keeping the application fast, reliable, and easy to maintain. This position offers a strategic opportunity to impact business metrics directly by reducing technical debt and optimizing application performance.

Success in this role requires active cross-functional collaboration. You will work directly with Backend, QA, and Product teams to clarify requirements, solve complex engineering challenges, and deliver a seamless UX. Additionally, you will contribute to architectural discussions, helping to shape the technical direction of the product alongside senior engineers.

Key Responsibilities

Design & Implementation

Develop and maintain high-quality cross-platform applications using React Native and TypeScript
Build reusable UI components and highly performant lists (utilizing tools like FlashList or FlatList) that strictly adhere to design specifications
Integrate mobile apps with backend services via RESTful APIs and WebSockets to ensure real-time data synchronization
Debug platform-specific issues using Xcode and Android Studio, and write or modify native modules (Swift/Kotlin) when standard libraries are insufficient

Engineering Standards & Quality

Champion code quality by writing clean, testable TypeScript code and actively participating in peer code reviews to ensure standards for readability and maintainability are met
Contribute to the long-term health of the codebase by identifying and fixing technical debt and improving overall test coverage
Participate in architectural discussions, offering input on state management (e.g., Redux Toolkit, Zustand) and navigation patterns to improve scalability

Performance, Reliability & Collaboration

Monitor production stability using tools like Sentry or Crashlytics, proactively identifying and fixing crashes or errors
Optimize app performance by focusing on specific metrics such as frame rates, memory usage, app size, and battery consumption
Assist in maintaining CI/CD pipelines to ensure smooth and reliable releases to the App Store and Google Play
collaborate effectively with non-technical stakeholders to explain technical constraints and propose viable solutions

Requirements

3+ years of professional software engineering experience, with at least 2 years strictly focused on React Native development
Strong proficiency in TypeScript and the React Native ecosystem (CLI, Hermes, debugging tools)
Solid understanding of iOS and Android build systems (Gradle, Pods, signing/provisioning). You must have the ability to read native code (Swift/Kotlin) to debug platform-specific issues
Familiarity with modern React patterns (Functional Components, Hooks) and state management libraries (Redux Toolkit, Zustand, or TanStack Query)
Experience writing unit tests using Jest and familiarity with End-to-End (E2E) testing concepts
Ability to explain technical concepts clearly to diverse teams
English: Upper-Intermediateorhigher (B2/B2+, written and spoken). You need to be able to communicate clearly in English to work effectively in an international team and participate in architectural discussions

Nice to Have

Experience launching and maintaining a B2C app with 100k+ Monthly Active Users (MAU)
Hands-on experience writing Native Modules or JSI/TurboModules from scratch
Familiarity with mobile analytics tools (Segment, Amplitude) and A/B testing implementation
Experience with automation tools like Maestro or Appium
Knowledge of backend fundamentals (Node.js) to debug API integrations effectively

Benefits

Your code will impact millions of users globally. Performance optimizations you implement will translate into immediate value and improved user experience
Work with the latest React Native tools and standards (TypeScript, Hermes, etc.) without being bogged down by legacy spaghetti code
A collaborative environment with rigorous code reviews and knowledge sharing - we value the best idea, regardless of title or seniority
A high level of ownership where you can see your features go live quickly in a fast-paced environment
15 days of paid vacation days
5 days of paid days off
5 days of paid sick leave
