About the team

Corporate IT drives many functions within Airwallex, including IT Support, IT Engineering, Corporate Networks, and Business Engineering at Airwallex. IT Engineering is the core team that drives our technology experiences from collaboration and automation, AI to hardware, applications, identity and access management. We design, build and run the systems and services our Airwallex team uses to build our product, serve our customers and run our business. We partner with every team in the business and solve some of the most difficult problems for our business, all at lightning speed.

What you’ll do

You will be part of a team working on new product features, and solving difficult problems for our business across our internal IT systems and finance systems with the goal of dramatically improving operational efficiency. You’ll work across our product and our internal teams to build features in our product, focusing on our procurement and ERP functions. This will include integrations with ERP systems, our Airwallex product, and integrations to and from the Airwallex Platform.

This will appeal to you if you’re excited to work on many things across multiple areas, with a lot of opportunity to build from zero.
