How you'll make impact

As a Staff Software Engineer, you’ll architect, design, and build secure, scalable systems that power Airwallex’s lending platform and enable fast, seamless, and compliant credit experiences.

Lead design reviews, shape systems architecture, and mentor engineers while raising the bar for code quality, technical excellence, and engineering practices.

Build resilient, high-throughput services that perform reliably at global enterprise scale, supported by strong testing, observability, monitoring, and operational discipline.

Partner with Product, Risk, Compliance, and other engineering teams to evolve the platform and support expansion into new financing products.

Own the technical foundations that enable secure, scalable lending services and APIs for enterprise clients and their users.

This is an in-office role — you’ll be in our Singapore office five days a week.
