Descripción del empleo

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. Read our operating principles to see it in full.

How you'll make impact

You'll help build backend services that connect Cash, Yield, Lending, and other Airwallex product surfaces into a unified financial experience for businesses. You'll deliver core financial workflows, including moving funds between accounts, optimising liquidity, and responding to activity across payments, card spend, and collections.

• Build reliable financial infrastructure such as reconciliation controls, unit registries, investment ledgers, and integration rails.
• Write high-quality, testable code and contribute to observability, API design, and maintainable engineering practices.
• Partner with Product, Infrastructure, Design, and other engineering teams to turn complex financial requirements into simple customer experiences.

• You own the outcome and you don't wait for permission to fix what's broken.
• You enjoy working closely with people across multiple countries and time zones as part of one connected, global team, including flexing your hours occasionally to make that connection work.
• You say what you mean. You're direct, but you lead with respect.
• You simplify complexity rather than hiding behind it.

Learn more about your team

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.
