Senior React Native Engineer

Job Description

We’re looking for a Senior React Native engineer (7+ years) who’s solved real mobile platform challenges in production.

At Washmen, our customer app isn’t just another e-commerce interface—it’s a high-volume, multi-service platform processing thousands of daily orders with complex orchestration requirements. We need someone who’s already debugged production memory issues with native profilers, built custom bridges when off-the-shelf solutions failed, and made architectural decisions that scaled.

What we’re NOT looking for: Junior developers eager to learn React Native, or web developers transitioning to mobile.

What we ARE looking for: Engineers who’ve shipped apps with published App Store/Play Store experience, can immediately contribute to discussions around performance optimization, native module development, and mobile-specific constraints.

If you’ve led mobile architecture decisions in production environments and have battle scars from React Native at scale—let’s talk.

Responsibilities

Design and build high-performance mobile applications using React Native for iOS and Android.

Build and maintain custom native modules in Swift/Objective-C (iOS) and Kotlin/Java (Android) when JavaScript isn’t enough.

Debug and optimize native-level performance issues using Xcode Instruments and Android Studio Profiler. Handle crashes, memory leaks, and platform-specific problems.

Integrate third-party native SDKs and handle OS updates across both platforms.

Manage API integration (REST/GraphQL) and state management using React Query, with focus on caching and error handling.

Translate designs into pixel-perfect UIs that work seamlessly on both platforms.

Write testable code with unit, integration, and E2E tests (Jest, Appium).

Mentor teammates through code reviews and pair programming.

Required Skills

Native Expertise (Critical):

Solid iOS (Swift/Objective-C) and Android (Kotlin/Java) fundamentals

7+ Experience building custom native modules and React Native bridges

Deep understanding of React Native architecture (New Architecture, JSI, Turbo Modules)

Strong debugging skills with native profilers and crash analysis tools
