Staff Software Engineer, Risk

Airwallex is the AI-native financial operating system for a real-time intelligent economy. More than 676000 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. Were 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.

Were co-headquartered in San Francisco and Singapore with more than 2300 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. Read our operating principles to see it in full.

Risk Platform builds the decisioning infrastructure that sits between Airwallex and every dollar that moves through it protecting 150000 businesses moving over US$260 billion a year across 200 countries and 90 currencies and deciding often in milliseconds whether a new signup is real a payment is safe or a login is who they claim to be. The hard part is that fraud evolves fast and every decision carries a two-sided cost: miss an attack and money is lost over-block and a legitimate business cant get paid. We build this with streaming pipelines processing billions of events a day graph databases exposing coordinated fraud rings ML models scoring every transaction and LLM agents that triage alerts. You dont need a fintech background just an appetite for adversarial systems problems where the scoreboard is measured in dollars. If you want to help scale one of the worlds fastest-growing financial platforms safely this is the team.
