About The Team

We're a newly formed team inside Airwallex, operating like a startup within a global fintech leader. Our mission is to reimagine how businesses interact with finance by moving beyond infrastructure and tooling into intelligent systems that can perform real financial work. This is a trillion-dollar opportunity, and we're assembling a world-class engineering team to make it real. Engineers here are hands-on builders who balance long-term architecture with rapid, thoughtful execution.

About The Role

You'll be a core builder in our AI team, designing and deploying intelligent systems that automate complex, multi-step workflows. You'll leverage agentic frameworks, advanced orchestration, and pragmatic model selection to take ideas from whiteboard to production.

What You'll Do

• Architect and deploy AI agents using frameworks like LangChain, LlamaIndex, AutoGen, CrewAI, Semantic Kernel, and emerging OSS stacks.
• Apply the right techniques across the AI spectrum — prompting, RAG, fine-tuning, or training from scratch.
• Design and optimize agent architectures for reasoning, tool use, and workflow automation.
• Build systems that improve with usage, creating compounding AI flywheels.
• Work with backend and frontend engineers to integrate AI reasoning into secure, production systems.

What You Need To Have

• 2+ years in applied AI/ML engineering with production deployments.
• Strong Python skills and experience with ML frameworks (PyTorch, JAX, TensorFlow).
• Track record of building and deploying AI agents, orchestration frameworks, or multi-step reasoning systems.
• Understanding of monitoring, evaluation, and iteration in production AI systems.
• Ability to balance innovation with reliability, scalability, and compliance.
