About the team

Our Mobile Team is responsible for the end-to-end development of both our iOS and Android apps, leveraging the latest technologies to build a seamless user experience.

You’ll be joining Airwallex at a pivotal moment as we expand the capabilities of our modern, fully native mobile apps. These apps empower customers to manage global B2B payments, submit and approve expenses, and control both virtual and physical Airwallex cards- including seamless Apple Pay and Google Pay integration for card transactions.
