Lead an approximately 10-person QA team across multiple services, managing testing, quality improvements, and stakeholder feedback while building AI-enabled verification processes. Remote work is available.
About this role
The server-side engineer will develop APIs for new features and batch processing for Pococha, a live communication service connecting streamers and viewers. Responsibilities include developing and improving new features, events, and administration screens; evaluating the effects of new features and events; and improving the efficiency of operational processes.
The role includes tuning API and other system performance by identifying and correcting slow processing based on slow logs. The engineer will consider and rebuild architecture suited to a social live platform, while addressing challenges associated with service growth, including increasing traffic, management of multiple environments, technical debt, and AI adoption.
Within the assigned team, the engineer will prepare product requirements documents and similar materials for projects, manage project risks, and improve development processes to increase the team's efficiency. The work spans new feature development, infrastructure improvement, technical-debt reduction, performance tuning, and stability improvements for a high-traffic service with complex event logic.
The posting describes opportunities to identify system improvements directly and to provide technical guidance and support inside and outside the team. The development environment names Cursor, GitHub Copilot, Claude, and Gemini as AI tools that can be used.
The initial work locations are DeNA's Shibuya office in Tokyo, the Yokohama Arai Building office, or the Yokohama BASEGATE office. Remote work is also permitted from the employee's home or another company-approved equivalent location. The stated scope of change is any workplace designated by the company, including remote-work locations.
