About the Role

We are seeking an experienced Senior Systems Developer to lead the evolution of our Warehouse Management System (WMS) as we transition from a vendor-managed solution to full in-house ownership.

This is the first internal development role in this space and will suit someone who enjoys stepping into an existing codebase, understanding inherited architecture, and taking ownership of a mission-critical operational platform. You will play a key role in stabilising, enhancing, and future-proofing the system ahead of a planned 2026 handover, while helping establish structured development practices within the organisation.

Cardinal is a leading partner to many of New Zealand’s well-known companies in food, beverage, grocery and personal healthcare.  We offer an end-to-end logistics solution to our customers, which offers the opportunity for our team members to develop, upskill and progress within the business.  We are revolutionizing supply chains with New Zealand’s first fully automated 3PL warehouse with AI driven robotics.
