CloudLinux Tech Stack
Linux OS and security platform for shared hosting providers
CloudLinux operates a purpose-built Linux OS and security stack (Imunify360) for hosting service providers and datacenters managing multi-tenant environments. The tech mix—pytest, Python, Jenkins, Kubernetes, PostgreSQL, MongoDB, Redis—combined with heavy adoption of infrastructure-as-code tooling (Terraform, Ansible, ArgoCD, Flux) and a shift away from OpenNebula, points to a company modernizing its virtualization and deployment layers. The hiring surge is skewed heavily toward senior and lead engineers (24 senior roles out of 33 engineering hires), with parallel investment in security and QA—a pattern consistent with hardening a kernel-level product against the compliance and vulnerability-management demands of enterprise hosting customers.
