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 AI team is at the heart of our company’s data and AI strategy. We're building a world-class, customer-facing analytics product that turns data into business impact through AI. As a Senior AI Engineer, you'll build the agent systems at the heart of it — turning natural-language questions into trustworthy, accurate answers over business data that our customers can rely on.

This is a role for someone who pairs deep AI engineering with solid data engineering foundations — comfortable not just building agents, but understanding the data and metrics they reason over and what makes those answers reliable. You'll own meaningful problems end to end and set a high bar for technical quality.

We're committed to building a diverse and inclusive team, and we welcome applicants of all backgrounds. You don't need to meet every qualification to apply — if you're excited about this work and meet the essentials, we'd love to hear from you.

This role is based in Singapore.

What you'll do

• Design, build, and ship AI agent applications and agent harnesses that answer business questions accurately over governed data.

• Build core agent capabilities, including retrieval-augmented generation, natural-language-to-query, and tool or function calling.

• Improve AI output quality through prompt and context engineering, evaluation benchmarks, guardrails, and ongoing quality measurement.

• Partner on governed metrics, data models, and data pipelines so agents can reason over consistent, reliable, and secure business data.

• Apply strong data governance and security practices, including the safe handling of sensitive data, to meet financial-services standards.

• Contribute strong engineering judgment to technical design and review, and help raise the technical bar across the team.
