Senior Cloud Native Engineer (OpenStack & Networking) (m/w/d)

Role Summary

noris network AG stands for innovative, secure and sustainable IT solutions. With over 600 committed employees, we develop high-performance services in the areas of cloud, data center, network & security and managed applications - operated on a state-of-the-art, multi-certified IT infrastructure with our own high-security data centers. We have grown continuously since 1993 and are now one of the leading IT specialists in Germany. Our greatest asset? A strong, diverse team with a common goal: to actively shape the digital future of our customers. That's why we promote personal responsibility, further development and fresh ideas - in an environment that combines innovation and sustainability.

Do you not only want to configure cloud networks, but also understand and further develop their architecture?

For you, networking doesn’t end at the switch port? Would you like to know how virtual networks, routers, security groups and load balancers work together through an OpenStack platform - and what happens if packet flows, MTU, overlay networks or routing do not work as intended?

Then design the technical basis of the noris Sovereign Cloud with us. We operate an open cloud platform based on OpenStack in our own German data centers. We combine open source, automation and technical freedom of design with high requirements for availability, security and auditability. The platform is aimed at digital sovereignty, open interfaces and operation according to the BSI's C5 criteria.
