ABOUT THE TEAM The Citizen Developers Infrastructure team sits within the Infrastructure & Productivity organization and is responsible for the internal platform that powers critical business processes at Airwallex. We build and operate a citizen‑developer platform that lets non‑product engineering groups safely build and run workflows and automations. Our goal is to make it easy and safe for these “citizen developers” to ship value quickly while embedding security, compliance, and software engineering best practices by default. This role is based in Singapore.
