Senior Mobile Engineer

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 2,300 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.

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. On iOS, we work with SwiftUI, Combine, and Async/Await, while on Android we use AndroidX, Coroutines, Hilt, and a suite of Jetpack libraries.

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.
