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 2,700 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.

You're comfortable owning the roadmap yourself.
You're comfortable with ambiguity. Give you a problem, not a prescription, and you'll run with it.
You default to action. You'd rather course-correct in motion than wait for perfect clarity.
You say what you mean. You're direct, but you lead with respect.
You simplify complexity rather than hiding behind it.
The Business Accounts team is where Cash, Yield, Lending, and the rest of our product suite come together into one unified financial experience for businesses. We're building the intelligent orchestration layer that lets customers move funds between transactional, yield-generating, and lending accounts, optimize liquidity, and respond dynamically to activity across payments, card spend, and collections. The challenge is that this connective layer doesn't exist yet: as our product suite grows, customers need it to feel programmable and automated, not like a patchwork of separate accounts. This is a brand-new team at an early stage, so you'll shape the technical foundations of a core platform from the ground up. If you want ownership building the product that sits at the center of Airwallex's business customer experience, this is where that work happens.
