CloudLinux / TuxCare is a remote-first infrastructure and security company. More than 300 engineers build and operate products used by hosting providers, enterprises, and internal service teams worldwide. Our Infrastructure Department runs the platforms behind CloudLinux OS, Imunify, KernelCare, TuxCare ELS, and our engineering systems. We are hiring a Senior Database Reliability Engineer to join the Infrastructure DBA cell. This is a hands-on production ownership role, not a narrow ticket-processing DBA position. You will keep critical database services reliable, automate repeated work, support engineering teams, and reduce single-person dependency in our PostgreSQL, ClickHouse, MongoDB, and Redis operations. PostgreSQL is the main requirement. ClickHouse experience is a strong plus, but it is not a day-one blocker. We need a senior engineer with enough database, Linux, automation, and incident-response depth to learn our ClickHouse environment quickly and operate it safely....

The problem you'd own Imunify360 is a multi-layer Linux server security suite — WAF, IDS/IPS, malware scanning and cleanup, proactive defence, patch management, reputation — running as an agent on hundreds of thousands of customer servers, backed by a cloud estate of scanning, correlation and signature-delivery services on our own bare metal. Roughly 70 components currently ship without a defined service level indicator. Some are internal services we can scrape. Many are agent-side subsystems running on machines we do not own, reporting through a heartbeat we designed for something else. There is monitoring, and there are dashboards, and there is no coherent answer to the question "is this component doing its job right now, and how would we know if it stopped?". We know the cost of that gap precisely, because we recently paid it: a security control was silently disabled across a large fraction of the fleet for 61 days. Every dashboard was green. The telemetry reported...

CloudLinux is transforming the Linux infrastructure market by ensuring security and stability for over 500,000 servers worldwide. Our products - CloudLinux OS, TuxCare, and Imunify360 - are the de facto standard in the hosting industry and Enterprise segment. We are seeking a visionary engineer to lead the evolution of our data platform. In 2025, we are shifting from classic database administration to an Internal Database-as-a-Service (DBaaS) model. We need a specialist who doesn’t just "configure backups," but designs resilient distributed systems, writes code to automate infrastructure, and transforms databases into a reliable service for product teams. If you are tired of endless tickets and want to build platforms capable of processing petabytes of data, this role is for you. Your Challenges & Responsibilities: DBaaS Architecture: Design and implement a self-service platform based on Terraform and Ansible , enabling the deployment of HA clusters (PostgreSQL...

CloudLinux and TuxCare build Linux, security, and enterprise infrastructure products used by hosting providers, software vendors, and engineering teams around the world. The Infrastructure team runs the platforms behind that work: data centers, public cloud providers, OpenNebula, Kubernetes/Talos, Ceph, CI/CD, observability, identity and access systems, and internal services. We are hiring a hands-on Senior Cloud Network Engineer & Architect to own and evolve the network layer of our hybrid infrastructure. This is an engineering role with real architecture ownership: you will design, implement, monitor, document, automate, secure, and troubleshoot production networking across data centers, cloud regions, Kubernetes/Talos clusters, OpenNebula environments, and bare metal. This is a technical ownership role. It is not a diagrams-only architecture position, and it is not a people-management role. You will define technical solutions, ship production changes, verify behavior,...
