Kubernetes Software Engineer

Company Description

At Kubermatic, we believe that businesses should focus on their core purpose: writing groundbreaking applications, not operations. In line with our commitment to make Kubernetes as easy as possible, we help IT teams worldwide to fully automate their Kubernetes and cloud native operations across multi-cloud, edge, and on-prem.

As one of the top corporate contributors to the Kubernetes Project, we develop enterprise-grade software solutions and provide professional services and support to safely navigate and accelerate your cloud native transformation. Our open source Kubermatic Kubernetes Platform makes it easy to operate thousands of Kubernetes clusters on any infrastructure.

If you are looking for a neatly structured environment, we are just not a good match. But if you are thrilled by the prospect of joining a technology start-up with a lot of room for your own ideas and personal growth, we definitely should at least have a chat.
