About the team

The Business Accounts Team is building the intelligent orchestration layer for Airwallex’s business account ecosystem - connecting Cash, Yield, Lending, and broader Airwallex product surfaces into one unified financial experience for businesses.

As Airwallex continues to expand its product suite, our customers increasingly need programmable, automated, and intelligent ways to manage their money: moving funds between transactional accounts, yield-generating accounts, and lending facilities; optimising liquidity; and responding dynamically to business activity across payments, card spend, collections, and future product lines.

Business Accounts is a new strategic domain designed to power this next generation of financial automation. This is a high-impact opportunity to join a new team at an early stage, shape the technical foundations of a core business platform, and build products that sit at the centre of Airwallex’s business customer experience.
