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. Read our operating principles to see it in full.
The Global Treasury and Payment Network (GTPN) team sits at the core of Airwallex’s payment infrastructure. As Airwallex’s very first product and still the largest revenue driver across the company, GTPN underpins many of our most critical customer experiences. We operate at the intersection of traditional and modern finance, expanding the reach of our global treasury and payment network, strengthening its capabilities and reliability, and delivering innovative payment products built on a robust financial foundation.
GTPN is a truly global, cross-site engineering organization, with talented engineers in existing and emerging hubs such as the US, Singapore, Hong Kong, and Shanghai. As we continue to scale worldwide, we’re looking for passionate Senior Software Engineers to join us. You’ll collaborate closely with product managers, designers, and engineers across regions to build and enhance products that not only meet but exceed our customers’ expectations.
