React Native Engineer in भारत

Pay: up to $100/hour

As a React Native Engineer, you will work remotely on an hourly paid basis to review AI-generated React Native code, mobile app architectures, and technical explanations, as well as produce high-quality reference implementations and step-by-step reasoning for complex engineering problems. You will assess solutions for correctness, clarity, security, performance, reliability, and adherence to the prompt; identify issues in React rendering/state, navigation, native-module integration, platform differences (iOS/Android), performance bottlenecks, memory/leaks, offline behavior, and release practices; fact-check technical information; write high-quality explanations and model solutions that demonstrate best practices; and rate and compare multiple AI responses based on correctness and reasoning quality.

This fully remote, hourly paid contractor role is with SME Careers, a fast-growing AI data services company and subsidiary of SuperAnnotate that provides AI training data to many of the world’s largest AI companies and foundation model labs—where your frontend expertise will directly help improve the world’s premier AI models used by millions of developers worldwide.

Important:

There is no immediate project for this role; however, if qualified, you will be among the first experts we reach out to when relevant opportunities arise. This will also provide you with access to future projects available through our expert network.

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.

Requirements

• 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 (2+ years preferred).
• 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.
• Previous experience with AI data training, annotation, or evaluating AI-generated technical content is a strong plus.
• Highly detail-oriented and systematic, with a methodical approach to evaluating reasoning quality and identifying subtle issues in complex mobile code.
