  • Optimize API communication for speed and reliability.

Performance & Application Stability

  • Monitor and improve:
    • Application speed
    • Responsiveness
    • Memory usage
    • Battery efficiency
    • Overall stability
  • Identify and resolve crashes, bugs, and performance bottlenecks.
  • Ensure applications perform consistently across supported devices and operating systems.
  • Build with scalability and long-term maintainability in mind.

Testing & Quality

  • Test features across multiple devices and operating system versions.
  • Debug application issues and resolve defects before release.

  • Monitor applications after deployment and resolve production issues quickly.

What Makes You a Strong Fit

You:

  • Enjoy building mobile products people actually use.
  • Care about both engineering quality and user experience.
  • Can translate designs into polished, functional interfaces.
  • Think about performance, scalability, and maintainability.
  • Troubleshoot technical issues independently.
  • Communicate effectively with product, design, and backend teams.
  • Take ownership from development through production release.

Required Experience & Skills

  • 3+ years of mobile application development experience.
  • Strong experience with iOS and/or Android development.
  • Hands-on knowledge of:
    • Swift
    • Kotlin / Java
    • iOS SDK
    • Android SDK
  • Experience with cross-platform frameworks such as:
    • React Native

    • Application lifecycle
  • Familiarity with architecture patterns such as:
    • MVVM
    • MVC
    • MVP
  • Strong understanding of mobile UI/UX best practices.
  • Experience with Git and collaborative development workflows.
  • Strong debugging and problem-solving skills.

Nice to Have

  • Experience publishing production applications to the Apple App Store and Google Play Store.
  • Experience with:
    • Firebase
    • Push notifications
    • Mobile analytics
    • Authentication systems
  • Experience building:
    • Offline-first functionality
    • Real-time features
    • Mobile animations
  • Startup or product-company experience.
  • Experience improving performance for applications with growing user bases.

What a Typical Day Looks Like

You may start by reviewing current development priorities and debugging an issue reported in production.

Throughout the day, you could:

  • Build new mobile features.
  • Implement designs into responsive interfaces.
  • Integrate APIs and backend services.
  • Debug application issues.
  • Optimize performance.
  • Test functionality across devices.
  • Review code and collaborate with other engineers.
  • Prepare new builds for production release.

In short: you build and maintain mobile applications that are fast, stable, visually polished, and easy to use.

Key Metrics for Success

  • Application stability and crash-free performance.
  • Fast and reliable feature delivery.
  • Smooth performance across supported devices.
  • Successful App Store and Google Play releases.
