We are shaping the future of how millions of patients interact with their dental practice. We aim to solve tough, real-world problems by continuously innovating in the product space. We are growing our team to expand the global reach of our products.

We’re a global healthcare tech leader with a local feel. At Henry Schein One, you’ll work alongside smart, supportive teammates in a company that values innovation, impact, and inclusivity. Our products improve lives and so do our people.

About the role

As we continue to grow, we’re looking for a Principal Developer to join our Auckland-based engineering team. We require a hands-on technical leader who thrives on solving complex problems, mentoring others, and driving architectural decisions with real business impact.

This is a senior-level role with high visibility and influence. You’ll collaborate across squads, steer design decisions, elevate engineering capability, and help shape the technical direction of the organisation.

Our Tech & Tools

We use a modern mix of technologies to support both legacy and greenfield systems:

• Primary: C#, .NET, .NET Aspire, Entity Framework, Blazor, TypeScript
• Secondary: PHP, C++, Ruby on Rails, Kotlin, Angular, Ember, Vue
• Databases: SQL Server, PostgreSQL, Cosmos DB
• Cloud Platforms: Azure & AWS (compute, messaging, storage, monitoring, IoT, etc.)
• Containerisation: Kubernetes, Azure Container Apps, Docker
• DevOps: CI/CD via Azure DevOps
• Infrastructure as Code: Bicep, Terraform

The way we work

We are not looking for ticket takers, we’re looking for problem solvers. Our teams are given problems supported by rich context and customer insight and empowered to deliver solutions using modern tools and technology.

We take ownership from idea to production. Our developers design, build, ship, and run the software they create. That means deep involvement in architectural decisions, quality practices, and operational excellence.

We work with both modern and legacy platforms and apply creativity and pragmatism to continuously enhance the customer experience.
