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
Airwallex’s Information Security team partners closely with engineering, IT, and other stakeholders to protect our systems, data, and employees while enabling the business to move quickly. The team helps build and maintain strong security practices across the company—from secure product and infrastructure design to risk reduction, incident response, audits, and compliance—so security is built into how we operate, not treated as a blocker.
