Our Mission

Our mission is to collaborate on a technology that revolutionizes how traditional data center infrastructure operations can gracefully absorb next-generation workloads without churn and additional technological complexity. Digital Rebar (aka DRP) enables upgrade and continuous deployment automation for production-scale deployments of technology such as Docker, Kubernetes, Cloud Foundry, etc.

Join Our Team

We are always looking individuals who have empathy for data center operators and a passion for reducing their toil with automation.  If this sounds like you, contact us at info@rackn.com for future consideration. At this time, we are only accepting resumes for candidates that can work in the US without additional assistance.
