Senior React Native Developer
First seen by Alion on Aug 21, 2026.
We're seeking a Senior React Native Developer with 10+ years of experience building secure, high-performance cross-platform mobile apps.
The ideal candidate is expert in React Native (JavaScript/TypeScript) with working knowledge of native Android (Kotlin/Java) and/or iOS (Swift/Objective-C) for bridging and platform-specific modules.
Strong emphasis on mobile security, AI-native development, and the full app lifecycle.
Key Responsibilities :
- Lead design, development, and deployment of secure React Native apps across iOS and Android; contribute to native modules as needed.
- Architect scalable, maintainable, high-performance apps using React Native, TypeScript, and native bridging where applicable.
- Implement secure coding practices, encryption, secure storage, authentication, and secure networking; conduct security audits and fix vulnerabilities.
- Use libraries such as React Navigation, Redux/Zustand/Context API, Axios/Fetch, Firebase, and native SDKs (Jetpack Compose, CocoaPods); securely integrate third-party APIs/SDKs.
- Leverage AI coding assistants (Claude Code, GitHub Copilot, etc.) to accelerate development, code review, and test generationwhile ensuring quality and security of AI-generated code.
- Debug and optimize for performance, memory, battery, and security; perform code reviews; mentor junior developers.
- Collaborate with product, design, backend, and QA teams; contribute to planning and estimation.
- Ensure compliance with App Store/Google Play policies and mobile security frameworks.
Skills & Qualifications :
- Experience : 8+ years in React Native development; apps published on Google Play and App Store; experience with native modules (Kotlin/Java and/or Swift/Objective-C).
- Languages : Expert in JavaScript/TypeScript; working knowledge of Kotlin/Java and/or Swift/Objective-C.
- Frameworks : React Native (including New Architecture Fabric/TurboModules), state management (Redux/Zustand/MobX), navigation, REST/GraphQL integration, and native platform frameworks (Jetpack Compose/MVVM, SwiftUI/UIKit).
- Security : Encryption and secure storage (Keychain, Keystore, encrypted AsyncStorage/MMKV), data privacy compliance, secure networking, familiarity with OWASP MSTG.
- AI-Native Development : Hands-on daily use of AI coding assistants (Claude Code, GitHub Copilot) for code generation, refactoring, debugging, and testing; skilled at prompting AI agents for scaffolding and integrations; understands risks of AI-generated code (insecure suggestions, hallucinated APIs, IP concerns) and applies mandatory human review.
- Tools : Git, Azure DevOps, CI/CD (Fastlane, App Center, Bitrise).
- Architecture : MVVM, Clean Architecture, common design patterns (Factory, Adapter, Observer) applied consistently across cross-platform and native code.
- Other : Strong UI/UX collaboration skills; full app lifecycle expertise (build, submit, deploy, monitor, maintain); performance profiling; excellent communication and cross-functional collaboration.
Preferred Qualifications :
- Advanced security : code obfuscation, reverse-engineering prevention, SSL pinning, API hardening.
- Cloud experience (Azure, Firebase, AWS) for secure mobile-backend communication.
- Experience customizing AI agent workflows (Claude Code commands/skills, Copilot Workspace, MCP integrations).
- Agile experience (Scrum/Kanban); knowledge of analytics, unit/A-B testing, and monetization strategies.
- Bachelor's degree in computer science or equivalent.
