About the Role

We are looking for an experienced Senior Android Engineer to take ownership of a modern native Android application built with Kotlin, Jetpack Compose and a modular Gradle architecture.

This is a hands-on engineering role where you will work closely with product, design, backend, platform and QA teams to build high-quality, scalable mobile features across reusable UI components, networking, authentication and secure identity-verification journeys.

You will contribute to both product delivery and the ongoing evolution of the Android architecture, with a strong focus on code quality, security, performance and maintainability.

Key Responsibilities

• Own, develop and maintain the native Android application using Kotlin and Jetpack Compose

• Build maintainable Compose features using established Android architecture patterns and Hilt dependency injection

• Contribute to a modular codebase with dedicated application, network, core, reusable-component and design-system modules

• Integrate backend services through the application networking layer, supporting authentication and API-based customer journeys

• Integrate and maintain third-party SDKs and identity-verification capabilities, including Jumio-based journeys where applicable

• Develop secure device and customer journeys in line with Android security and fintech requirements

• Build and maintain reusable Jetpack Compose components aligned with the application design system

• Use Kotlin Serialization and KSP-based tooling where required by the codebase

• Write and maintain unit, integration and UI tests and contribute to reliable, testable software design

• Support multiple application flavors and environment-specific configurations for development and release builds

• Contribute to Android build, release and distribution processes, including Firebase App Distribution

• Support production monitoring and application observability using New Relic

• Participate in code reviews, technical design discussions and continuous improvements to application quality and architecture

• Ensure development activities are carried out in line with applicable regulatory, security and compliance requirements

What We’re Looking For

• University degree in Computer Science, Engineering or a related field

• Minimum 5 years of professional experience in Kotlin and native Android development

• Hands-on experience building production Android features with Jetpack Compose

• Solid understanding of Android application architecture and state-driven UI development

• Hands-on experience with Hilt dependency injection

• Experience working with modular Android applications and reusable components or libraries

• Experience integrating backend APIs, authentication or identity services and third-party SDKs

• Experience with Kotlin Serialization and familiarity with KSP-based code generation

• Good understanding of Android security best practices, including secure token and credential storage

• Experience with Gradle Kotlin DSL and dependency management using version catalogs

• Strong knowledge of Android Studio, debugging and performance-analysis tools

• Experience writing unit and UI tests using appropriate Android testing frameworks

• Familiarity with Git-based collaborative development workflows and code reviews

• Experience working in an Agile delivery environment

• Strong communication, ownership and collaboration skills

Nice to Have

• Experience with Jumio or another KYC / identity-verification SDK

• Experience developing reusable Jetpack Compose design systems and component libraries

• Experience with Firebase tooling, particularly Firebase App Distribution

• Experience with New Relic mobile monitoring and production observability

• Experience working with product flavors and environment-specific Android configurations

• Previous experience in fintech, wallets, payments or financial-services mobile applications

• Knowledge of Android CI/CD pipelines, particularly in Azure DevOps

• Familiarity with Fastlane and Android release automation

• Familiarity with Kotlin Multiplatform as an additional, future-oriented capability

What We Offer

• Fully remote working model

• Opportunity to take ownership of a modern, production-scale native Android application

• Hands-on work with Kotlin, Jetpack Compose and modern Android architecture

• Exposure to complex mobile journeys across authentication, identity verification and financial services

• High level of technical ownership and influence on application architecture and engineering quality

• Collaborative environment working across product, design, backend, platform and QA teams

• Competitive compensation based on experience
