Senior Software Engineer - Organization & Identity

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. Read our operating principles to see it in full.

How you'll make impact

You'll shape the long-term technical vision for Airwallex's identity, authentication, and core account domains. You'll work on highly available, cloud-native systems that secure our platform and support global scale.

• Own the technical vision and architecture for our Identity and Access Management and account infrastructure domains.

• Build highly available, cloud-native IAM products and account infrastructure using Java or Kotlin.

• Partner with Product, Security, Compliance, Legal, and Engineering teams to turn business and regulatory requirements into scalable technical roadmaps.

• Improve engineering quality through thoughtful system design, code reviews, automated testing, and best practices for performance, reliability, and security.

You'll work from our Singapore office five days a week.
