Mid-Level Android Engineer

About this role

This full-time Android engineering role is based in Tokyo and focuses on the company's own food and health app, as well as other Android applications developed with client companies. The engineer will design, develop, operate and improve mobile applications from requirements definition through release.

Day-to-day work includes analyzing user activity, reporting findings, proposing improvements to the app experience, considering new features, testing and debugging, releasing updates, reviewing code from other developers, and maintaining the mobile CI/CD environment. Candidates who want to work beyond mobile development may also contribute to server-side API development. The role also includes considering and implementing technical measures that improve development efficiency.

The posting lists experience publishing an Android application on Google Play, keeping up with Android development trends, and knowledge of or experience with Android application architectures such as MVP, MVVM and Clean Architecture as welcome qualifications. Experience developing GUI applications with Jetpack Compose, whether professionally or independently, is also welcomed. No specific education or years-of-experience threshold is stated.

The development environment uses a MacBook Pro and Android Studio. The Android application architecture is MVVM, with Android Jetpack components including Jetpack Compose, AAC, Navigation Component, Room, WorkManager and Paging Library. Other named technologies include Kotlin Coroutines Flow, Dagger Hilt and Epoxy. Infrastructure primarily uses AWS, with services deployed on ECS; GCP is used for analytics and machine-learning-related tasks. CircleCI is used for nearly all services, and the wider toolset includes Git, GitHub and GitHub Copilot.

The products address food, healthcare and medical support. The company develops the consumer and patient meal-management app Oishi Kenko, the Kakaris meal-guidance solution for medical institutions, and solutions for health insurance associations. Its work brings together engineers, designers and registered dietitians, and uses food and health data in collaboration with medical universities for research and publications. The Android engineer joins a cross-functional product-development setting focused on applications that support everyday health management.

The company states that it uses remote work and core-time flextime. Online interviews are available. New employees receive onboarding during their first six months, including monthly one-on-one lunches with a mentor and regular meetings with the CEO. The company also holds welcome lunches and quarterly internal events.
