About this role

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.

HOW YOU'LL MAKE IMPACT

You’ll build and operate goal-oriented AI agents that automate SRE, DevOps, and DBA workflows across Airwallex’s global infrastructure, including incident investigation and remediation, infrastructure provisioning, deployment orchestration, database operations, and capacity management.

• Design reliable agent architectures with planning, reasoning, tool use, error recovery, safety guardrails, auditability, and human-in-the-loop escalation for systems that interact with production infrastructure.

• Integrate agents with Kubernetes, Terraform, AWS, GCP, Aliyun, databases, monitoring and observability platforms, and CI/CD pipelines through well-designed tool interfaces.

• Define evaluation frameworks and metrics such as task completion rate, accuracy, time to resolution, and escalation rate to measure and improve agent performance.
