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

- Architect distributed payment systems at global scale, designing and evolving core infrastructure across real-time local clearing, SWIFT, and proprietary treasury routing in 150+ countries.
- Solve complex financial integrity problems by building idempotent, fault-tolerant systems for multi-currency reconciliation, asynchronous settlement, and compensation logic across unreliable banking partners.
- Own the reliability and observability of the payment network by defining SLAs, designing for graceful degradation during partner outages, and building real-time payment health monitoring.
- Use payment telemetry to optimise routing, identify bottlenecks, and measure how infrastructure changes affect settlement speed and conversion.
