ATTRIBUTES WE VALUE

We hire successful builders with founder-like energy who want real impact, accelerated learning, and true ownership. You bring strong role-related expertise and sharp thinking, and you’re motivated by our mission and operating principles https://www.airwallex.com/us/operating-principles. You move fast with good judgment, dig deep with curiosity, and make decisions from first principles, balancing speed and rigor.

You're humble and collaborative; turn zero‑to‑one ideas into real products, and you “get stuff done” end-to-end. You use AI to work smarter and solve problems faster. Here, you’ll tackle complex, high‑visibility problems with exceptional teammates and grow your career as we build the future of global banking. If that sounds like you, let’s build what’s next.

RESPONSIBILITIES

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.

WHAT YOU WILL DO

• 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.

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.

Join our team as we redefine what software development looks like when AI agents are the primary operators. Apply now to become a Senior Software Engineer at Airwallex and help us build the infrastructure for the agentic era.
