Senior CX Engineer

About Contacx
Buddy Advisory is proud to be partnering with Contacx, a leading Amazon Connect partner helping organisations across APAC rethink how they engage with their customers.
Contacx designs and delivers contact centre solutions on Amazon Connect, bringing AWS-integrated AI to some of the region's most customer-focused businesses. They work closely with AWS and many of their projects come straight from that partnership. The team works across Melbourne, Perth and the Philippines, in small, focused delivery squads.
Contacx is now expanding into New Zealand, where demand for a dependable local delivery partner is growing fast. It's an early-stage build inside an established, scaling business.
The Role
As a Senior CX Engineer, you will lead the architecture, design, and deployment of cloud-native customer experience solutions built on Amazon Connect and the AWS ecosystem. You will bridge complex client business requirements with high-performance engineering execution, driving technical excellence across WebRTC, real-time communications, serverless integrations, and AI-driven CX workflows.
As our most senior role in NZ, you will be on a path to becoming our first NZ squad leader, a remit that will oversee all our NZ clients, sit on our ANZ senior leadership team, and contribute to our company strategy and operational optimisation.
