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 2,700 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.

How you'll make impact

You’ll build and run the experimentation engine behind Airwallex’s global growth: what we test, how we test it, and how we know when we’re right.

Own the end-to-end execution of growth experiments and campaigns, translating strategic hypotheses into operational workflows, coordinating launches and rollouts, and synthesising learnings to inform the next iteration.

Manage the experimentation backlog, campaign calendar, measurement approach, tracking taxonomy, dashboards, QA processes, and reporting across Commercial, Growth, Product, Engineering, Marketing, Data and Legal.

Identify gaps in tooling and process, then codify repeatable work into scalable systems, including checklists, QA scripts, readout templates and registry libraries. Use AI with clear guardrails and human review before anything customer-facing goes live.

Partner with FP&A on forecasting and budget tracking, balancing speed with experimental rigour, data quality and effective cross-functional execution.

You’ll work from our San Francisco office on Mondays, Wednesdays and Thursdays.
