Airwallex is an AI-native financial operating system serving over 675,000 businesses globally, including McLaren Racing, Qantas, SHEIN, and TikTok. The company provides regulated financial infrastructure spanning North America, Europe, the Middle East, and Asia-Pacific, with headquarters in San Francisco and Singapore and 2,300+ employees across 27 offices.
As a Staff Software Engineer on the Ecosystem & Integration Platform team, you will lead the technical direction of Airwallex's ecosystem platform, which connects financial products with the software customers already use. Your responsibilities include:

- Designing and evolving platforms and integrations across accounting, HR, ERP, marketplace, payment, and open-banking systems.
- Building secure, reliable APIs, SDKs, webhooks, and UI-extension patterns that enable third-party developers and partners to build on Airwallex.
- Improving developer experience through documentation, sandboxes, and tooling.
- Partnering with engineering, product, design, and go-to-market teams to deliver secure, reliable experiences.
You will work from the Singapore office five days a week and own the roadmap yourself, making decisions with incomplete information and moving quickly. The role requires connecting dots across functions while maintaining both big-picture vision and technical detail.
