About this role
ABOUT AIRWALLEX
Airwallex is the AI-native financial operating system for a real-time, intelligent economy. More than 675,000 businesses, including McLaren Racing, Qantas, SHEIN, and TikTok, use us, directly or through our platform partners, to run their financial operations or build and monetize financial products of their own.
We started in Melbourne in 2015 to build the infrastructure global commerce runs on. We're the regulated backbone behind global payments: not by accident, but by design. A decade plus, 85+ licenses, and a financial infrastructure spanning North America, Europe, the Middle East, and Asia-Pacific.
We're co-headquartered in San Francisco and Singapore, with more than 2,700 people across 27 offices. We hire builders with founder-level energy, people who move fast with good judgment, dig in with real curiosity, and make calls from first principles rather than waiting to be told what to do.

HOW YOU'LL MAKE IMPACT
You’ll own the reliability, security, and day-to-day operation of Airwallex’s Korean production database environment supporting cross-border payment products. You’ll operate and optimise PostgreSQL, Redis, and Redis Cluster environments across Google Cloud, with a secondary AWS footprint, while partnering with local product, engineering, security, and compliance teams and our global DBA team.
- Own high availability, replication, failover, backups, and disaster recovery for production database environments.
- Drive compliance with Korean data residency and security requirements across backups, replicas, and snapshots.
- Build automation for provisioning, configuration, access management, and operational processes using scripts, software, and infrastructure-as-code.
- Improve database reliability and performance through monitoring, alerting, schema standards, indexing, query optimisation, and incident troubleshooting.
