Mission Brief

At Axturis Technologies in Salzburg, you are the guardian of our cloud-native platform. Our products rely on a secure, resilient and well‑engineered infrastructure – and you ensure that every layer, from Kubernetes to identity management, meets the highest standards.

You understand cloud architecture, you know how to harden it and you verify that it stays that way.

You move confidently across Kubernetes, container security, identity and access management, API protection and operational monitoring. You are both an engineer and an auditor: you design secure foundations and you validate that our systems and processes follow them. If you enjoy being the technical conscience of a modern cloud platform, this role is for you.
