Software Engineer (Mobile)

This is a remote position.

Cross-Platform

• Build and maintain applications using React Native or equivalent frameworks.
• Develop reusable cross-platform components.
• Integrate native Android functionality into cross-platform applications.
• Develop native modules where platform-specific functionality is required.
• Manage platform-specific behaviour.
• Maintain consistency between native and cross-platform components.

Application Architecture

• Define mobile application architecture.
• Design state-management strategies.
• Establish networking and API integration patterns.
• Define reusable components.
• Make informed native vs cross-platform decisions.
• Maintain code quality and technical consistency.

Transaction & Financial Workflows

Where applications support financial transactions:

• Implement transaction initiation and confirmation.
• Handle processing, success, failure, timeout, and unknown states.
• Prevent duplicate submissions.
• Display accurate transaction status.
• Implement transaction history and receipts.
• Recover correctly from interrupted application flows.

Network Resilience

Applications must work reliably under poor network conditions.

You will design for:

• Intermittent connectivity.
• Network switching.
• Request timeouts.
• Retry strategies.
• Background processing.
• Application termination.
• Interrupted workflows.
• Recovery from uncertain transaction states.

Security

Implement appropriate mobile security controls including:

• Secure token and credential storage.
• Biometric authentication.
• Secure API communication.
• Certificate/public-key pinning where appropriate.
• Protection of sensitive data.
• Secure local storage.
• Root/jailbreak risk detection where appropriate.
• Screenshot/screen-capture protection for sensitive screens.

Performance

• Optimise application startup.
• Reduce memory consumption.
• Improve rendering performance.
• Reduce unnecessary network requests.
• Optimise application size.
• Investigate device-specific issues.
• Test against low-spec Android devices.

Requirements

Required Experience

• 5–8 years of professional mobile development.
• Strong native Android experience.
• Strong Kotlin experience.
• Strong Android architecture knowledge.
• Production experience with React Native or another cross-platform framework.
• Strong understanding of asynchronous programming.
• Experience integrating APIs and third-party services.
• Experience with mobile application security.
• Experience debugging production applications.
• Strong understanding of application lifecycle and state management.
• FinTech or banking applications.
• Payment applications
• Biometric authentication
• Mobile CI/CD.
• Mobile application security testing.
• Offline/network-resilient application design.

What We Look For

You should be able to demonstrate:

• Native Android applications you have shipped.
  
• Cross-platform applications you have built or maintained.
  
• How you decide between native and cross-platform implementation.
  
• How you integrate native functionality into React Native.
  
• How you handle interrupted transaction flows.
  
• How you manage application state.
  
• How you approach mobile security.
  
• How you diagnose production crashes.
  
• How you optimise applications for constrained devices.
