[Remote] Senior Software Engineer, Infrastructure AI

Note: The job is a remote job and is open to candidates in USA. Airwallex is a unified payments and financial platform for global businesses, empowering over 200,000 clients with integrated solutions. They are seeking a Senior Software Engineer for their Infrastructure AI team to design and build AI agents that automate infrastructure operations, enhancing the efficiency of SRE, DevOps, and DBA workflows.ResponsibilitiesBuild 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 managementDesign 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 predictableIntegrate 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 interfacesEvaluate 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 goalsCollaborate 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 capabilitiesShape 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 teamSkills5+ years of professional software engineering experience, with strong proficiency in backend languages such as Python, Go, Java, or KotlinHands-on experience building agentic AI systems: You have designed and built AI agents that autonomously plan, reason, and execute multi-step tasks using LLMs. This includes agent loop design, tool-use orchestration, and managing agent state and memory. This is a core requirement, not a nice-to-haveInfrastructure 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 inStrong system design skills with the ability to architect reliable, safe, and scalable agent systems that interact with production infrastructureExcellent communication and collaboration skills, with a track record of working effectively across cross-functional teams in a global environmentExperience with agent orchestration frameworks (e.g., LangGraph, CrewAI, AutoGen, or custom agent frameworks) and LLM APIs (OpenAI, Anthropic, etc.)Experience with observability and monitoring systems (Grafana, Prometheus, Datadog, ELK stack) — either building them or building agents that interact with themExperience with database administration or automation (schema migrations, query optimization, backup/recovery) — knowledge that helps build effective DBA agentsUnderstanding of SRE practices: incident response, runbooks, postmortems, SLOs/SLIs — the operational domain these agents will automateA forward-thinking mindset about where AI agents are headed. You have opinions on agent reliability, safety, evaluation, and the path toward increasingly autonomous infrastructure systemsCompany OverviewAirwallex is a global payments and financial platform that provides business accounts, payment solutions, and spend management tools.
