Senior Android Developer – Consumer Banking App

About the role

A large-scale consumer banking application is hiring hands-on Android engineers to build and support critical customer journeys and shared native capabilities. The team works in a single shared native codebase serving multiple business domains, so engineers must consider how their changes affect the whole app. This is an engineering role, not a lead, architect or delivery-lead position.

Required profile

• Four or more years of commercial Android development in Kotlin, with production code written personally in the last 12 months.
• Ability to work confidently in an established codebase that also contains Java.
• Experience beyond small or single-owner apps; candidates focused on team management, project management, Scrum-master work, vendor coordination or architecture governance will not be considered.

Required skills

• Android SDK and lifecycle in a large multi-team codebase: Activity and Fragment lifecycle, configuration changes, process death, state restoration, task and back-stack behaviour, background execution limits, modularisation, and Jetpack Compose integration.
• Concurrency and memory under real conditions: Coroutines and Flow, structured concurrency, dispatcher selection, main-thread contention, race conditions, and diagnosing context leaks and listener retention via heap analysis.
• Platform security: Android Keystore, encrypted local storage, BiometricPrompt, certificate pinning, permissions, scoped storage and root/tamper detection.
• Production debugging: ANR, jank, frame drops, startup time, crash analysis and device/OS fragmentation, diagnosing from customer symptoms to root cause.
• Preferred: API or SDK upgrades in production, App Links and custom URL schemes, WebView/hybrid integration, banking/fintech experience, internal SDK or design system contribution, observability instrumentation, and CI/CD or test automation ownership.
