🎯 The Role

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.

✅ Key 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 their goals.
• Collaborate cross-functionally: Partner with SRE, DevOps, and platform engineering teams to identify the highest-value workflows for agent automation. Understand real operational pain points and translate them into agent capabilities.
• Shape the future of infrastructure AI at Airwallex: Contribute to the technical vision for how AI agents will transform infrastructure operations. Stay at the forefront of agentic AI developments and bring new ideas into the team.

📌 Required Qualifications

• 5+ years of professional software engineering experience, with strong proficiency in backend languages such as Python, Go, Java, or Kotlin.
• Infrastructure and cloud knowledge: Practical experience with cloud platforms (AWS, GCP, or Aliyun), container orchestration (Kubernetes), infrastructure-as-code (Terraform), and CI/CD systems. You understand the domain the agents will operate in.
• Strong system design skills with the ability to architect reliable, safe, and scalable systems.
• Experience with building or working with AI agents, autonomous systems, or similar technologies is a plus.
• Strong problem-solving skills and a passion for tackling complex, high-visibility problems.

⭐ Desirable Experience

• Experience with AI agent platforms, multi-agent systems, or large language models.
• Experience with infrastructure automation, SRE, or DevOps practices.
• Experience with observability tools, monitoring systems, or incident response.
• Experience with database management, database operations, or database automation.
• Experience with CI/CD pipelines, deployment automation, or release management.
