Senior Software Engineer, Infrastructure AI

About Airwallex Airwallex is the AI-native financial operating system for a real-time, intelligent economy. More than 676,000 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 2,300 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. Read our operating principles to see it in full. About the Team Airwallex’s Infrastructure & Productivity team is on a mission to turn everyday software engineers into superheroes. The team builds and maintains the internal platforms, tooling, and CI/CD infrastructure that power Airwallex’s global engineering organization, serving hundreds of engineers across multiple offices and time zones. The team is now pioneering a bold new direction: an AI agent ecosystem where goal-oriented agents continuously operate across every repository — automating infrastructure operations, incident response, database management, and DevOps workflows. Built on Quartermaster, our internal agent platform, these agents autonomously plan, reason, and execute multi-step tasks against real infrastructure. You will be joining at the ground floor of this initiative, building the intelligent systems that fundamentally change how infrastructure work gets done at Airwallex. What You’ll Do As a Senior Software Engineer on the Infrastructure AI team, you will design, build, and operate goal-oriented AI agents that automate SRE, DevOps, and DBA workflows across Airwallex’s global infrastructure. You won’t be doing operations work yourself — you’ll be building the AI systems that do it. Your agents will autonomously investigate incidents, provision infrastructure, manage databases, execute deployments, and handle the operational tasks that traditionally require human intervention. You will work on top of Quartermaster, Airwallex’s internal agent platform, building domain-specific agents that interact with real infrastructure tooling (Kubernetes, Terraform, cloud APIs, databases, monitoring systems). This role requires you to think deeply about agent architecture — planning and reasoning loops, tool selection and execution, safety guardrails, human-in-the-loop escalation, and how to make autonomous systems reliable in production infrastructure environments. This hybrid role is based in Seattle, WA. Responsibilities Build goal-oriented infrastructure AI agents: Design and implement autonomous agents on the Quartermaster platform that handle SRE, DevOps, and DBA workflows — including incident investigation and remediation, infrastructure provisioning, deployment orchestration, database operations, and capacity management. Design agent architectures for safety and reliability: Build robust agent loops with planning, reasoning, tool-use, error recovery, and human-in-the-loop escalation. Infrastructure agents touch production systems — they must be safe, auditable, and predictable. Integrate agents with infrastructure tooling: Give agents the ability to interact with real systems — Kubernetes, Terraform, cloud APIs (AWS, GCP, Aliyun), monitoring/observability platforms, databases, and CI/CD pipelines — through well-designed tool interfaces. Evaluate and improve agent performance: Define metrics for agent effectiveness (task completion rate, accuracy, time-to-resolution, escalation rate). Build evaluation frameworks to measure whether agents reliably achieve thei
