About the role
The successful candidate will join BNZ’s Technology team within the Lending Platforms domain, working across the platforms and integration services that support lending application processing and decisioning for both personal and business customers. The role has a primary focus on Secured Lending. The wider business unit is responsible for the technology that underpins key lending experiences and services for BNZ customers.

The role also offers the opportunity to help lead new work as the team transitions to building integrations with BNZ’s banking platforms.
