The Mission:

Millions of people open their banking app every day, and it can't freeze or show a blank screen when a backend service slows down. You'll make the Android app keep working through outages, and you'll help build Open Banking features that let customers link accounts from other banks.

The Role:

This is a contractor role open to candidates based in Australia. You'll join a mobile engineering squad at one of Australia's largest banks and build an offline-first architecture in Kotlin and Jetpack Compose. It uses a SQLite persistence layer, with networking and database code generated from gRPC definitions. The first 2 to 4 weeks are onsite in Melbourne, then it moves to hybrid.

Most Significant:
5+ years of senior native Android engineering, with expert Kotlin and Jetpack Compose
Production experience with offline-first apps on SQLite: local caching, schema migrations, and thread-protected data sync
Kotlin Coroutines and Flow, used to keep UI rendering separate from background network work
Hands-on gRPC, Protocol Buffers, and automated code generation on Android
Clean Architecture, MVVM or MVI,



and dependency injection with Hilt or Dagger
Android security fundamentals: Keystore or EncryptedSharedPreferences, certificate pinning, and OAuth2
Based in Australia and able to work onsite in Melbourne for the first 2 to 4 weeks

The Bonus Skills:
Code-generation tools that map API definitions to SQLite schemas and DAO interfaces
LaunchDarkly or similar feature flagging, for staged rollouts and kill-switches
Working knowledge of Swift and SwiftUI, to keep behavior consistent with the iOS squad
FinTech background: financial dashboards, Open Banking (Consumer Data Right), or retail banking apps

Personal Traits:
You design for the bad day. When an API times out, the screen keeps working.
You prefer strongly typed contracts over loose JSON, and you like it when tooling generates the boilerplate.
You treat security and pen test findings as part of the build, not a review at the end.
You share context easily, with a current team onsite and with iOS colleagues after that.
