Create ResumeReact Native native modules are one of the clearest signals that a developer can operate beyond basic UI work and handle real mobile engineering complexity. Companies hiring senior React Native engineers increasingly expect candidates to integrate native iOS and Android SDKs, bridge platform APIs, manage permissions, resolve native dependency conflicts, and support device-level functionality like biometrics, Bluetooth, NFC, maps, push notifications, and background services.
Most React Native developers can build screens. Far fewer can confidently work with Swift, Kotlin, Objective-C, Gradle, CocoaPods, Xcode, Android Studio, TurboModules, JSI, or platform-specific debugging. That gap matters in hiring.
If you want to qualify for higher-paying React Native roles in fintech, healthcare, logistics, enterprise SaaS, or IoT, native module expertise is often what separates mid-level developers from senior mobile engineers.
React Native native modules allow JavaScript code to communicate directly with platform-specific iOS and Android code.
This enables React Native apps to access functionality that does not exist in the JavaScript runtime alone, including:
Camera APIs
Bluetooth communication
NFC readers
Biometric authentication
Apple Pay and Google Pay
Push notification systems
Background services
Recruiters and engineering managers use native integration experience as a proxy for technical depth.
When companies evaluate React Native engineers, they often divide candidates into two categories:
These developers typically:
Build screens and flows
Consume APIs
Use existing npm libraries
Work mostly in JavaScript or TypeScript
Avoid native debugging
Depend heavily on Expo-managed workflows
These candidates are common.
Native analytics SDKs
Secure storage
HealthKit and Google Fit
Maps and geolocation
Deep linking and app links
Device sensors
File system operations
Without native modules, React Native apps are limited to what pure JavaScript libraries expose.
From a hiring perspective, developers who understand native modules are viewed differently because they can solve platform-level problems instead of depending entirely on third-party packages.
These developers can:
Build custom native bridges
Modify iOS and Android native code
Integrate proprietary SDKs
Debug native crashes
Resolve dependency conflicts
Handle native permissions properly
Configure release pipelines
Work with Swift, Kotlin, Java, or Objective-C
Support production mobile releases
These candidates are significantly harder to find.
That scarcity directly impacts compensation, contract rates, and hiring competitiveness.
Not all integrations carry equal value in the job market.
Recruiters prioritize integrations that indicate real engineering complexity, platform knowledge, security awareness, or production reliability.
Biometric authentication is heavily used in:
Fintech apps
Healthcare platforms
Enterprise authentication systems
Banking products
Secure internal tools
Common implementations include:
Face ID
Touch ID
Android BiometricPrompt
Secure keychain authentication
Device credential fallback
Hiring managers value this experience because it combines:
Security considerations
Native permission handling
Platform-specific APIs
User authentication flows
Good Example
Weak Example
The first example signals technical implementation depth. The second sounds generic and low-level.
Camera integration becomes significantly more complex in production apps.
Real-world camera work often includes:
Barcode scanning
OCR processing
Document capture
Video recording
Frame processing
Real-time image analysis
Permissions management
Native compression handling
Senior engineers are expected to understand:
AVFoundation on iOS
CameraX or Camera2 on Android
Native permission flows
Performance optimization
Memory management
Recruiters often associate advanced camera work with logistics, delivery, healthcare, AI, or retail applications.
Bluetooth and NFC integrations are strong indicators of advanced engineering capability because they involve:
Hardware communication
Background connectivity
Platform limitations
Native threading concerns
Device compatibility issues
These integrations are common in:
IoT applications
Medical devices
Smart lock systems
Warehouse logistics
Industrial software
Retail scanners
Candidates with BLE experience are often evaluated more favorably for senior mobile roles because debugging hardware communication issues requires strong platform understanding.
Basic map rendering is not impressive anymore.
What employers actually value is experience with:
Background location tracking
Route optimization
Geofencing
Offline map support
Native map SDK customization
Performance optimization for large datasets
Senior candidates typically discuss:
Battery optimization
Foreground services
iOS location restrictions
Android background execution limits
Permission edge cases
This signals real production experience.
SDK-heavy applications are extremely common in enterprise environments.
Typical SDK integrations include:
Payment SDKs
Banking SDKs
Identity verification tools
Analytics platforms
Fraud detection systems
Customer support SDKs
Marketing attribution SDKs
Healthcare integrations
This is where many React Native developers struggle.
Third-party SDKs often create:
Native dependency conflicts
Build failures
Version mismatches
iOS pod issues
Android Gradle issues
Permission conflicts
Architecture incompatibilities
Candidates who can resolve these issues independently are highly valuable.
Modern React Native companies increasingly prefer engineers comfortable with Swift and Kotlin.
Older Objective-C and Java knowledge still matters, but Swift and Kotlin now dominate modern native development.
React Native engineers frequently collaborate with native mobile teams.
Candidates who understand native codebases can:
Read platform crash logs
Modify native implementations
Contribute to shared mobile architecture
Troubleshoot release blockers
Upgrade native dependencies safely
This dramatically reduces team friction.
Most job descriptions mention “native module experience,” but hiring managers usually evaluate much more specific competencies.
Strong React Native engineers understand:
Xcode configuration
Provisioning profiles
Certificates
App signing
Info.plist configuration
CocoaPods dependency management
Build schemes
iOS permission declarations
Many developers underestimate how important release engineering knowledge becomes at senior levels.
Hiring teams also look for:
Android Studio familiarity
Gradle configuration
Android manifests
Build variants
ProGuard or R8
SDK version compatibility
Kotlin interoperability
Native dependency resolution
Android build issues are one of the biggest bottlenecks in React Native development.
Candidates who can solve them quickly stand out immediately.
Modern React Native architecture is becoming increasingly important in enterprise hiring.
Senior candidates should at least understand:
TurboModules
Fabric renderer
JSI architecture
Native threading models
Bridge performance limitations
Even if companies are not fully migrated, engineers who understand the new architecture are often viewed as more future-ready.
Most developers describe native work poorly on resumes and LinkedIn profiles.
Recruiters are scanning for evidence of:
Production-level platform experience
SDK integration complexity
Cross-platform debugging ability
Native dependency management
Release ownership
Hardware integration
Enterprise mobile reliability
Generic wording weakens candidate positioning.
This tells recruiters almost nothing.
This immediately communicates senior-level engineering depth.
These resume bullets work well because they show technical depth, platform knowledge, and business impact simultaneously.
Built custom React Native native modules to integrate proprietary iOS and Android SDK functionality for fintech payment processing
Integrated biometric authentication, secure storage, push notifications, and encrypted session handling across native mobile platforms
Resolved complex CocoaPods, Gradle, and native dependency conflicts during enterprise SDK upgrades
Developed platform-specific native bridges using Swift, Kotlin, Objective-C, and Java to support hardware device integrations
Improved app stability by implementing native fallback handling for platform permission failures and offline connectivity scenarios
Collaborated with native iOS and Android engineers to support release engineering, SDK migrations, and production debugging
Implemented BLE communication workflows for IoT-connected mobile applications with background reconnection handling
Optimized React Native bridge performance by reducing unnecessary native module calls and improving asynchronous event handling
Many developers only know how to install existing npm libraries.
That becomes a problem when:
Packages become abandoned
SDK support breaks
Native APIs change
Enterprise integrations require customization
Senior engineers are expected to go deeper than package installation.
Some React Native developers panic the moment they enter Xcode or Android Studio.
Hiring managers notice this quickly during interviews.
Common warning signs include:
Inability to explain build failures
No understanding of native logs
No familiarity with Gradle or CocoaPods
Weak platform debugging knowledge
This often blocks candidates from senior-level consideration.
Expo is useful, but relying exclusively on managed workflows can limit career progression for advanced mobile roles.
Companies building:
Banking apps
Healthcare systems
Enterprise tools
Logistics platforms
IoT products
often require native customization beyond Expo-managed capabilities.
Senior engineers usually understand both managed and bare workflows.
Strong React Native engineers know iOS and Android behave differently.
Examples include:
Background execution restrictions
Permission systems
Push notification handling
Deep linking behavior
Navigation transitions
Bluetooth capabilities
File system access
Candidates who speak about “mobile” generically often sound inexperienced.
Interview performance often depends less on syntax and more on engineering reasoning.
Strong candidates explain:
Why a native solution was necessary
How platform limitations were handled
What debugging process they used
How reliability was improved
Which edge cases caused failures
How release risks were mitigated
This sounds fundamentally different from tutorial-level React Native experience.
“We implemented a custom native bridge because the vendor SDK exposed functionality unavailable through existing React Native packages. We also had to handle different permission behaviors between Android 13 and iOS background execution policies.”
That signals real-world engineering maturity.
Some industries care far more about native integration depth than others.
Fintech companies heavily prioritize:
Biometrics
Encryption
Payment SDKs
Secure storage
Device trust validation
Fraud prevention integrations
Healthcare applications often require:
HealthKit integration
HIPAA-sensitive workflows
Device communication
Background monitoring
Secure authentication
Logistics platforms commonly use:
GPS tracking
Offline sync
Barcode scanning
Camera processing
Geofencing
Background services
IoT environments frequently require:
Bluetooth communication
NFC support
Device provisioning
Hardware pairing
Firmware communication
These industries consistently pay more for React Native engineers with native platform expertise.
If you want to move from mid-level to senior React Native engineering, native integration depth is one of the fastest ways to differentiate yourself.
Focus on building demonstrable experience in:
Native SDK integration
Platform debugging
Build environment troubleshooting
Native module creation
Hardware integrations
Release engineering
Performance optimization
Platform architecture understanding
Portfolio projects should reflect production complexity, not just polished UI work.
A simple CRUD app rarely impresses senior hiring teams anymore.
Hiring managers are trying to reduce risk.
When evaluating React Native engineers, they ask themselves:
“Can this person independently solve difficult mobile platform problems?”
Candidates who discuss:
Native crashes
SDK incompatibilities
Permission edge cases
Release blockers
Production debugging
Platform-specific failures
usually sound more senior because those are real engineering problems companies face daily.
The following skills consistently improve marketability and compensation potential:
Swift integration
Kotlin integration
Custom native bridge development
BLE and NFC integration
Payment SDK implementation
Background services
Native performance optimization
Release engineering ownership
Enterprise SDK integration
Mobile security implementation
TurboModules and JSI knowledge
Production debugging expertise
These capabilities are significantly harder to replace than basic UI development.
