Build AI Worker VoiceAgent’s web frontend, designing visual interfaces and admin features, selecting architecture, and delivering releases with TypeScript and React in a hybrid office/home role.
About this role
WinTicket, the CyberAgent subsidiary behind the WINTICKET online betting service for keirin and auto racing, offers a student internship for a Flutter engineer focused on improving test automation. The mobile app is built in Flutter, and its end-to-end tests use Flutter's official integration_test package to check each version for serious defects before a release. About seventy test scenarios cover the main user flows.
The tests have three problems: repairs after implementation changes are costly and hard to staff (the top priority), runs are sometimes unstable depending on environment and timing, and long run times slow development and verification. Left alone, this erodes trust in the tests. The intern is asked to lead the prototyping of a new way to maintain the end-to-end tests continuously, with generative-AI tools for generating and fixing test code in view.
The app team of eight, in a development organisation of about 60, works with Flutter, Dart, Riverpod, Freezed, GitHub Actions, Fastlane and AI tools such as Cursor and Claude Code. Applicants need at least one year of Flutter development and experience leading design, proposal and development to completion. Technical writing or talks, open-source work and review experience are preferred.
