About this role
This role provides technical leadership for the Android team developing ReceChallenge, a consumer savings and shopping-support app where users submit receipts to earn points. The app has surpassed 15 million downloads and is being developed as part of a broader effort to use receipt purchase data, OCR data, demographic information, and recipe-viewing history in the offline purchasing market.
The lead will set the Android architecture direction and make technology-selection decisions. Responsibilities include planning improvements to Android-specific performance issues such as application startup time and build time. The role also advances AI-assisted development by incorporating AI tools into implementation planning, code generation, and code review, and by establishing AI-supported development as a standard team process rather than an individual practice.
Technical leadership is the main focus, with additional responsibility for a small team. Duties include conducting one-to-one meetings, providing feedback, supporting technical development, and participating in hiring through technical interviews and feedback on the selection process.
The posting does not specify required years of experience, formal qualifications, or education. It identifies the Android environment as using Kotlin, with MVI and MVVM architectures.

Listed tools include Slack, Figma, Notion, Firebase, KARTE, and Redash.
The development organization provides a monthly AI allowance of 100,000 JPY to developers for selecting and combining AI tools for their work. Technical growth support includes operating a tech blog, encouraging and supporting conference presentations, and internal study sessions and knowledge sharing. The stated equipment includes a MacBook Pro M4 Max with 64 GB of memory and 1 TB of storage, replacement with the latest model every two years, a choice of JIS or US keyboard layout, a choice of 16-inch or 14-inch display, and a 27-inch 4K office monitor.
