Cloud Database Administrator

Power the Core of Nation-Scale Digital Payments

Join one of Japan’s leading FinTech ecosystems powering daily payment transactions for tens of millions of users nationwide. As part of the core Platform & Infrastructure team, you will manage mission-critical database systems that serve as vital social infrastructure while driving large-scale architectural modernization from on-premise environments to the public cloud.

What You’ll Do

• Drive Cloud Migration & Optimization: Lead the migration, modernization, and day-to-day operations of high-throughput database systems transitioning from on-premise to public cloud environments (AWS Aurora, GCP Spanner).
• Maintain High-Availability Systems: Manage, tune, and ensure uninterrupted performance of on-premise MySQL / MariaDB databases supporting core payment and financial services.
• Solve Complex Infrastructure Challenges: Lead operational problem-solving, troubleshoot critical bottlenecks, and introduce automation, IaC, and modern database reliability practices.

What We’re Looking For

• Database Management: 5 years of practical DBMS administration experience, with 3 years specifically in MySQL/MariaDB operations.
• Cloud Infrastructure: Proven hands-on experience managing databases in public cloud environments (particularly AWS Aurora).
• Infrastructure Focus: Core background in infrastructure/database administration rather than application development.
• Languages: Business-level Japanese (fluent stakeholder communication) and conversational English.

Nice-to-Haves

• Direct experience executing on-premise to public cloud database migrations.
• Modern operations tooling: Database operations with Git, Infrastructure as Code (IaC), or AI-driven process improvements.
• Exposure to multi-DBMS solutions (PostgreSQL, GCP Cloud Spanner) and database security baselines.
• People Management experience (small teams up to 5 people)

Why Apply?

• Massive Scale & Impact: Work directly on high-concurrency systems where stability and performance impact millions of consumer and merchant transactions every single day.
• Active Cloud Transformation: Play a pivotal hands-on role in modernizing legacy architecture to leading-edge cloud-native data platforms.
• Dynamic Global Environment: Collaborate within an innovative, tech-driven organization offering solid career growth and modern engineering practices.
