Job description

Join a team spread across the world and enjoy true location freedom while collaborating with talented engineers everywhere.

Work with top brands

Riot Games, Fox, Coinbase, Epic Games, and so much more.

Gamified community you'll love

Engage in online events, compete in challenges, and attend Outposts and summits that bring X-Teamers together learning, connecting, and leveling up globally.

Enjoy flexible schedules, wellness stipends, and support to make sure you're thriving both professionally and personally.

About the Role

You'll join a mobile engineering squad at one of Australia's largest banks, working on two priority projects: making the Android app resilient when backend services go down, and building Open Banking features that let customers link accounts from other banks.

The core of the work is an offline-first architecture. When backend APIs slow down or fail, the app keeps working instead of freezing or showing an empty screen. You'll build it in Kotlin and Jetpack Compose with a SQLite persistence layer, using networking and database code generated from gRPC definitions. Millions of customers use this app.

The contract runs 6 to 8 months. Expect the first 2 to 4 weeks onsite in Melbourne, to get context and share knowledge with the team.

Most Important

• 5+ years of senior native Android engineering, with expert Kotlin and Jetpack Compose

Production experience building offline-first apps with SQLite, including local caching, schema migrations, and thread-safe data synchronization

Kotlin Coroutines and Flow, used to keep UI rendering separate from background network work

Hands-on experience with gRPC, Protocol Buffers, and automated code generation on Android

Clean Architecture, MVVM or MVI, and dependency injection with Hilt or Dagger

Android security fundamentals: Android Keystore or EncryptedSharedPreferences, certificate pinning, and OAuth2

Able to work onsite in Melbourne for the first 2 to 4 weeks

Nice to Have

• Experience building or using code-generation tools that map API definitions to SQLite schemas and DAO interfaces
• LaunchDarkly or similar feature flagging, for staged rollouts and instant kill-switches
• Working knowledge of iOS patterns (Swift and SwiftUI), so you can keep behavior consistent with the iOS squad
• FinTech background: financial dashboards, Open Banking (Consumer Data Right) flows, or retail banking apps

You prefer strongly typed contracts over loose JSON, and you like it when tooling generates the boilerplate for you.

You treat security and penetration test findings as part of the build, not a review at the end.

You share context easily, with a new team onsite in the first weeks and with iOS colleagues after that.
