At Centrapay, we're revolutionising how you spend money both in-store and online. We allow businesses to create digital assets and loyalty programmes so that you can spend and be rewarded anywhere. Some of our partners include Coca-Cola, BNZ, and Farmlands, and we process payments in New Zealand and Australia. Our payments platform is the heartbeat of what we do. On top of this, we're building our hero app, Payap (www.payap.com), that brings all of our best capabilities to life. 👩‍💻 What you'll actually be working on These aren't abstract responsibilities, these are real projects from our roadmap: - Building self-service tools that let partners create their own economies: you'll be shipping flows that take a business from idea to live loyalty programme in under 10 minutes, with API abstractions that make complex economic systems feel like filling out a form. - Creating multiplayer money experiences in Payap: the split payments flow that handles the mate who never pays you back, shared challenges that make transactions feel like achievements, and group payment UX that works when half your mates have Payap and half don't. - Building fraud detection that protects without blocking legitimate transactions: designing signals that catch card testing attacks but not someone's $5.50 flat white, creating risk intelligence across thousands of merchants, and shipping monitoring that knows suspicious activity from lunch rush. 🏋️‍♀️ How we actually work - You build it, you run it, you own it: Engineers at Centrapay ship features end-to-end and see them through production. When something breaks or could be better, you have the context and autonomy to fix it, no waiting for permission or handoffs to other teams. - Learn by building: We give you business problems, not specs.

No ticket grooming, no story pointing. We also have 10% time and Hackathons where you can experiment with new tech you wouldn't normally get to use. - Progress over perfection: We deploy to production daily, and you'll push code on your first day. We believe in shipping early, iterating fast, and learning from real usage. - Work across the stack: Backend, frontend, infrastructure.
