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 2,700 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.

• Improve product requirements through product insight and data-driven feedback, strengthening system robustness and scalability.

• Raise financial data integrity by implementing and enhancing checks and processes that maintain accuracy and consistency.

What we're looking for

Essentials

• You have a strong foundation in backend software engineering, with expertise in languages such as Java, Kotlin, or equivalent.

• You have a deep understanding of customer and financial data needs, guiding your approach to software development.

• You work collaboratively, share knowledge, and embrace diverse perspectives to achieve collective goals.

You'll thrive here if

• You're comfortable owning the roadmap yourself.

• You've worked in a high-growth or scaling environment and know what it takes to build systems that need to grow with the business.
