iOS Tech Lead

About this role

This position serves as the technical lead for the iOS team developing ReceChallenge, a consumer savings and shopping-support app where users submit receipts to earn points. The lead sets architecture direction and makes technology-selection decisions, plans systematic improvements to iOS-specific performance issues such as app launch and build time, and incorporates AI tools into the development flow for implementation planning, code generation, and more efficient review. The role also helps establish AI-assisted development as a standard team process rather than an individual practice.

The position includes supporting people-management responsibilities for a small team. These include one-to-one meetings, feedback, and technical development for team members, as well as participation in hiring through technical interviews and feedback on the selection process.

The posting does not state specific required qualifications, years of experience, or educational credentials. It also does not state an employment type, salary, working hours, or language requirement.

ReceChallenge is described as having more than 15 million cumulative downloads. Users submit receipts to receive points, and the service uses receipt OCR data, demographic information, and recipe-viewing history to support marketing and data-utilization efforts related to offline purchasing for manufacturers and retailers. The wider service portfolio includes the Kurashiru recipe-video platform, described as having more than 44 million cumulative downloads. The mobile team is working on Swift 6 compatibility and improvements to multi-module builds.

The named iOS stack includes Swift, MVVM, MVI, SwiftUI, Swift Concurrency, XcodeCloud, GitHub Actions, Swift Package Manager, CocoaPods, SwiftLint, SwiftGen, Sourcery, Mockolo, Mint, and fastlane. The listed surrounding tools are Slack, Figma, Notion, and Redash, and the team uses Scrum development. AI-assisted development is promoted across the organization, and all developers receive a monthly AI allowance of JPY 100,000 for tools they choose.

The listed work location is in Minato, Tokyo. Additional development support includes operation of a technical blog, encouragement and support for conference presentations, and internal study meetings and technical knowledge sharing. The stated equipment includes a MacBook Pro M4 Max with 64 GB memory and 1 TB storage, updated to the latest model every two years. Keyboard layout can be selected as JIS or US, screen size as 16 or 14 inches, and the office provides a 27-inch 4K monitor. The development process is described as using one-week sprints, daily morning meetings, and Working Out Loud.
