Job description
Summary
SME Careers is a fast-growing AI data services company and subsidiary of SuperAnnotate. As a React Native Engineer, you will work remotely to review AI-generated React Native code and mobile app architectures, produce high-quality implementations, and assess solutions for various technical aspects.
Responsibilities
- Develop AI Training Content: Create detailed prompts across React Native topics and write high-quality reference answers to guide AI learning
- Optimize AI Performance: Evaluate and rank AI responses to enhance correctness, security, performance, and maintainability
- Ensure Model Integrity: Test AI outputs for inaccuracies or unsafe recommendations, validating reliability across real-world mobile use cases
Skills
- Bachelor's degree or higher in Computer Science, Software Engineering, or a closely related technical field (or equivalent practical experience)
- 4+ years of professional experience building production mobile apps, including React Native
- Strong proficiency in TypeScript and modern React (hooks, state management patterns, memoization, rendering behavior)
- Hands-on experience with React Native fundamentals: component patterns, gestures/animations, lists, image handling, deep links, and notifications (as applicable)
- Experience with navigation and app structure (e.g., React Navigation) and managing complex flows safely
- Strong understanding of platform-specific behavior and debugging on both iOS and Android (builds, logs, profiling, release issues)
- Familiarity with native integration: bridging/native modules, permissions, app lifecycle, and dependency management (CocoaPods/Gradle)
- Performance mindset: diagnosing and resolving jank, slow renders, large list performance, startup time, and bundle size
- Experience with data and networking: error handling, retries, caching, offline-first strategies, and secure storage basics
- Experience with testing and quality: Jest, React Native Testing Library, and E2E frameworks (Detox/Appium), plus CI/CD familiarity
- Minimum C1 English proficiency (written and spoken), with the ability to write clear technical explanations and follow detailed English-language guidelines
- Highly detail-oriented and systematic, with a methodical approach to evaluating reasoning quality and identifying subtle issues in complex mobile code
- 2+ years of experience with React Native preferred
- Previous experience with AI data training, annotation, or evaluating AI-generated technical content is a strong plus
