About The Role

Scrambly is looking for a skilled React Native Engineer to help build and scale the Scrambly 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.
