Cloud Architect (m/f/x)

Your Mission

You design and develop new features for our OpenStack-based public cloud, the SysEleven Stack, for the benefit of our customers.

In an interdisciplinary team, we also take responsibility for operations. We attach great importance to automating the processes behind operations and support so that we have time for the “exciting” topics – we operate the SysEleven Stack by developing the necessary software.
