Senior Software Engineer, Infrastructure & Productivity

Job Overview

As a Senior Software Engineer at Airwallex, you will join the Productivity team on a mission to make AI agents first-class participants in the software development lifecycle. You will build and operate the platforms that power autonomous software delivery — from AirDev, which runs AI agents that ship production code end-to-end, to AirForge, which lets anyone create web applications from natural language. You will operate with high ownership, taking features from design to production in a fast-paced environment where the tools you build directly multiply the output of hundreds of engineers.

Key Responsibilities

• Build AI Agent Infrastructure: Develop and extend AirDev, the platform where AI agents autonomously execute software development tasks — managing stories, orchestrating agent lifecycles, and integrating with GitLab, Jira, Confluence, and Slack.


• AI-Powered Application Factory: Contribute to AirForge, a containerized desktop application that uses Claude Code to generate, preview, and publish web applications — including its Electron shell, Express backend, React UI, and Docker-based sandbox runtime.


• Agent Governance & Workflow Orchestration: Help build Quartermaster and CREW (Customized Resilient Enterprise Workflow), the systems that provision, coordinate, and govern autonomous agent workflows across the organization.


• Event-Driven Integration: Design and maintain Kafka-based event pipelines, webhook handlers, and API integrations that connect AI agents to enterprise systems and enable closed-loop automation.


• Operational Excellence: Own the reliability of production agent infrastructure — monitoring, alerting, incident response, and continuous improvement of platform services running on Kubernetes.

Required Qualifications

• A minimum of 5 years of professional software engineering experience.


• Proficiency in Python and/or TypeScript/Node.js, with experience building production backend services.


• Hands-on experience with containerization and orchestration (Kubernetes, Docker) and cloud platforms (GCP preferred; AWS also relevant).


• Solid understanding of event-driven architectures, messaging systems (e.g., Kafka), and RESTful API design.


• Experience with the full software development lifecycle, including CI/CD pipelines, code review, and production operations.

Preferred Skills

• Experience working with LLMs, AI agents, or developer tooling — e.g., building with Claude, GPT, or similar APIs; prompt engineering; tool-use patterns; MCP (Model Context Protocol).


• Familiarity with Electron, desktop application development, or container-based sandbox environments.


• A product-oriented mindset — you care about developer experience and think about how the tools you build change the way people work.
