About The TeamThe 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. What You’ll DoAs a Senior/Staff Software Engineer on the Citizen Developers Infrastructure team, you will design, build, and operate the platform services that underpin Airwallex’s citizen‑developer ecosystem and internal workflow automation. You will partner closely with application teams and citizen developers to define tooling, patterns, and development processes, while continuously improving the platform abstractions and paved paths they build on. You’ll be responsible both for the developer experience and guardrails of the platform, and for the underlying workflow infrastructure that makes it reliable and scalable. ResponsibilitiesDesign, build, and evolve the citizen‑developer platform and tools that make it easy to create and operate automation / applications without deep infrastructure knowledge. Establish secure SDLC and guardrails for citizen‑developer‑built applications so compliance and security are baked in by default. Build self‑serve development and operations tooling that reduce dependence on central platform engineers. Design, build, and maintain the Temporal‑based workflow infrastructure, addressing challenges such as multi‑tenancy, high availability, and cost effectiveness. Contribute to the Kubernetes and GitOps foundation (ArgoCD, Helm, Terraform) that powers the platform, ensuring deployments are safe, repeatable, and auditable.
