Attributes We Value
We hire successful builders with founder-like energy who want real impact, accelerated learning, and true ownership. You bring strong role-related expertise and sharp thinking, and you're motivated by our mission and operating principles. You move fast with good judgment, dig deep with curiosity, and make decisions from first principles, balancing speed and rigor.
You're humble and collaborative; turn zero-to-one ideas into real products, and you "get stuff done" end-to-end. You use AI to work smarter and solve problems faster. Here, you'll tackle complex, high-visibility problems with exceptional teammates and grow your career as we build the future of global banking. If that sounds like you, let's build what's next.
Role and Project Scope:
As part of the Business Accounts Team, you will help build the intelligent orchestration layer for Airwallex's business account ecosystem - connecting Cash, Yield, Lending, and broader Airwallex product surfaces into a unified financial experience for businesses. This includes building systems that can support liquidity optimisation, automated transfers, and dynamic responses to business activity across payments, card spend, collections, and future product lines.
This is a high-impact opportunity to join a new strategic domain at an early stage. You will help shape the architecture, APIs, and technical foundations of a core business platform that sits at the centre of Airwallex's business customer experience and powers the next generation of financial automation.
This role is based in Sydney

What you need to know about the Melbourne Tech Scene
Home to 650 biotech companies, 10 major research institutes and nine universities, Melbourne is among one of the top cities for biotech. In fact, some of the greatest medical advancements were conceptualized and developed here, including Symex Lab's "lab-on-a-chip" solution that monitors hormones to predict ovulation for conception, and Denteric's vaccine for periodontal gum disease. Yet, the thousands of people working in the city's healthtech sector are just getting started, to say nothing of the tech advancements across all other sectors.
