The Opportunity : Join Our Stablecoin Platform Team

The Financial Markets team is responsible for Airwallex’s core FX and liquidity infrastructure.

This includes support for near-instant global payments, on-chain liquidity, and seamless conversion between fiat and stablecoin balances. We’re building stablecoins into the core of Airwallex’s infrastructure, so they function as seamlessly as any fiat currency across our global platform.

Experienced in integrating new systems into legacy or distributed environments without introducing instability or regressions.

Strong grasp of secure system design, particularly around private key handling, signing, encryption, and operational controls
