If you’re ready to do the most ambitious work of your career, join us.

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.

Corporate IT builds and runs the technology Airwallex runs on — laptops, identity, collaboration, automation, AI. We partner with every team in the company, from Finance to Engineering, to solve hard problems and build new solutions. We remove friction from technology, provide world-class support, and drive outcomes that help Airwallex move faster and go further.

As an IT Engineer, you’ll work in our IT Engineering function, owning our collaboration tool stack. You’ll be the primary owner of our Slack, Google Workspace, Zoom, and our collaboration surfaces our Airwallex uses to connect with our customers and work together every day. This is a technical, hands-on role, using code, integrations, clickops, command line, terminals and more. You’ll be an expert and own much of our Google Workspace operations, ensuring we build and manage a complex footprint across Google products and bring them all together with Identity engineering. You’ll need to be intensely curious, and relentless about solving hard problems. You’ll build integrations and workflows that solve our problems. You’ll work closely with INFOSEC, Revenue Operations and other IT teams across the world, ensuring we build secure and scalable solutions across the many regions where we operate. You’ll also drive onboarding and enablement of AI products and features in and around these products, experimenting, trialing and finally leveraging these tools to work faster, and drive your own results farther.
