Here at BNZ, it's about more than just banking. We work together in an agile, energising environment to create innovative solutions through our promise "If you can imagine a better future, let's find a way."

We support wellbeing, flexible working and have a generous leave offering. There is the opportunity for growth, learning and career development. No two days are the same.

We have an exciting opportunity for an Intermediate Developer to join our Customer portfolio within the Customer Onboarding and Identity domain.

You’ll join a technology tīma building microservices that provide trusted enterprise customer data across the bank. This is a core platform that underpins how customers are identified, onboarded, and interacted with.

This is a Wellington-based hybrid role with three days in the office and two days where you can work flexibly. Anchor days in the office are Tuesday and Wednesday, and either a Monday or Friday.
