Airwallex

Airwallex builds the financial infrastructure that powers global businesses. They handle payments, treasury, and spend management with AI baked in from the ground up. Founded in Melbourne in 2015, they're now processing billions annually for over 200,000 businesses—names like TikTok, Brex, Rippling, Qantas, and SHEIN trust them to move money across borders.

What makes them different is they own the full stack: proprietary infrastructure plus software plus AI. That means they can solve real problems—not just bolt AI on top of legacy systems. Businesses get multi-currency accounts, embedded financial products, and spend controls that actually work at scale.

They've got 2,200+ people across 26 offices globally, with major presence in APAC (Singapore, Hong Kong, Melbourne, Shanghai, Bangkok). If you're a data or ML engineer, there's serious infrastructure here—they're processing billions, managing complex regulatory landscapes across multiple jurisdictions, and using AI to detect fraud and optimize payments in real time.

Why this matters for professionals in Malaysia and Singapore: fintech in Southeast Asia needs infrastructure that works across borders and currencies. Airwallex is hiring across the region and tackling the exact problems that regional businesses face when they go global. You get to work on financial systems that move money for real companies, not toy problems.
