About Airwallex

Airwallex is the AI-native financial operating system for a real-time, intelligent economy. More than 675,000 businesses, including McLaren Racing, Qantas, SHEIN, and TikTok, use us, directly or through our platform partners, to run their financial operations or build and monetize financial products of their own.

We started in Melbourne in 2015 to build the infrastructure global commerce runs on. We're the regulated backbone behind global payments: not by accident, but by design. A decade plus, 85+ licenses, and a financial infrastructure spanning North America, Europe, the Middle East, and Asia-Pacific.

We're co-headquartered in San Francisco and Singapore, with more than 2,300 people across 27 offices. We hire builders with founder-level energy, people who move fast with good judgment, dig in with real curiosity, and make calls from first principles rather than waiting to be told what to do.

About the Team

The Agentic AI team designs intelligent, autonomous systems that eliminate financial operations for companies globally. We automate the core financial workflows that businesses rely on—turning slow, manual processes into something real-time, intelligent, and seamless, compressing hours of work into seconds.

The team blends deep research pedigree with proven industry experience. We operate with high standards, are tool-agnostic, and expect engineers to own problems end-to-end. We collaborate closely, push boundaries responsibly, and ship exceptional work quickly. You’ll solve unprecedented technical challenges using unique, end-to-end financial datasets no one else in the industry has.

About the Role

As a Staff AI Engineer, you will design and deploy intelligent systems that automate complex, multi-step financial workflows. You’ll leverage agentic frameworks, orchestration layers, and pragmatic model selection to turn ideas into reliable production systems at scale.

Responsibilities

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.

Qualifications

5+ 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.
