Mobile Developer (Android/iOS)

Full-time

BJAK

The Role

We are looking for mobile developers to build BJAK's AI Neobank App across Android and iOS.

This role is for strong mobile builders who can ship clean, reliable and intuitive mobile experiences, whether their main strength is Android, iOS or both.

What You'll Own

  • Build and ship mobile features for Android and/or iOS.
  • Create simple mobile flows for insurance, payments, claims, renewals and financial services.
  • Work with product, design and backend teams to turn complex journeys into usable mobile products.
  • Integrate APIs and handle edge cases, loading states, errors and production issues.
  • Improve app performance, reliability, crash rate and user experience.
  • Support fast product launches, experiments and iterations across mobile journeys.
  • Help set high standards for mobile product quality across the app.

What We're Looking For

  • 3+ years of mobile development experience in Android, iOS or both.
  • Strong experience with Kotlin and/or Swift .
  • Experience shipping production apps used by real users.
  • Strong product sense and attention to mobile UX.
  • Able to work with APIs, analytics, crash logs and production feedback.
  • Fast, practical and comfortable owning work with limited handholding.
  • App links, GitHub, screenshots or examples of shipped work are a strong advantage.

The Kind of Builder We Want

  • Thinks like a product builder, not just a mobile coder.
  • Cares about smooth flows, small details and real user behaviour.
  • Can work across ambiguity and ship without waiting for perfect specs.
  • Takes production quality personally.
  • Honest about what they built directly versus what the wider team delivered.

This Role Is Not For

  • Developers who only want to build isolated screens.
  • People who do not care about UX, performance or reliability.
  • Candidates who cannot explain their own contribution clearly.
  • People who need heavy guidance for every task.
  • Engineers who move slowly in a high-growth environment.
