Senior DevOps Engineer (Kubernetes)

Working in cloud environments is becoming our everyday life, which gives us many benefits. As part of Comarch, we develop the Comarch Infraspace Cloud (CIC) platform based on Openstack, which allows us to quickly create environments using virtualization (IaaS) and ready-to-use services (PaaS).
One of the services that we intensively develop in the PaaS model is Kubernetes. Thanks to the work of our team, CIC platform’s users can quickly start deploying applications using Kubernetes.
Do you want to work with the latest technologies and carry out the development of the Kubernetes service in the cloud environment? Do you like to solve original problems and challenges and want to constantly develop? We are looking for engineers who are passionate about Kubernetes, the Openstack platform, new technologies and good DevOps practices who will be involved in the development of PaaS services within the Comarch Infraspace Cloud platform.
If you cannot imagine your daily work without Kuberentes, join our team today!
