Realnaut is a Madrid-based infrastructure consultancy focused on cloud migrations and DevOps transformation, founded in 2022. Their tech stack—Kubernetes, Terraform, AWS, ArgoCD, GitHub Actions—reflects a GitOps-first approach to infrastructure. Active projects center on CI/CD pipeline optimization, Kubernetes cluster deployment, and CloudFormation-to-Terraform migrations, while pain points around testing standardization and quality culture suggest they're helping clients move from manual, fragmented practices into automated, observable systems. The hiring mix is engineering-heavy (10 of 12 active roles) skewing mid-to-senior, indicating rapid scaling of delivery capacity.
