Site Reliability Engineer / Cloud Operations Engineer (f/m/d)

German companies and public administrations in this country are ready to accelerate their digital transformation and the use of AI—but they will never compromise on the security of their most sensitive data. This is where Thales in Germany, in partnership with Google Cloud and our new company currently being established, comes into play. With a new, 100% German business unit, we are providing a concrete response to the strict requirements of the BSI. What we are creating is a locally and fully autonomously operated “Trusted Cloud”. It provides access to the broadest service portfolio on the market, while everything remains strictly under European jurisdiction. By combining German and French standards such as SecNumCloud, C5 and C3-A, we offer our customers unequaled resilience and business continuity. This is a turning point for our industry and a decisive step towards a strong, sovereign digital Europe.

• Drive operational excellence by creating and maintaining technical documentation, standardizing incident response procedures, and continuously improving operational playbooks.
• Lead and contribute to post-incident reviews, root cause analyses, and the implementation of preventive measures to improve platform reliability.
• Identify opportunities for automation and contribute to improving operational efficiency, scalability, compliance, and service reliability.
• Support the operation of highly secure cloud environments designed to meet stringent regulatory and sovereignty requirements.

We are looking forward to:
