Jobs at Cloudlinux

Remote internship contributing to CloudLinux projects, focusing on C systems development and kernel backporting. Tasks include coding, debugging, code reviews, unit testing, and collaborating with engineers to ensure stability across Linux distributions.

Own and improve production PostgreSQL reliability, disaster recovery, automation, and observability. Support ClickHouse, MongoDB, and Redis operations, automate DBA workflows (Ansible, Terraform/OpenTofu, GitLab CI/CD), build self-service DB tools, and drive incident response, runbooks, and measurable RTO/RPO targets.

Own and deliver major KernelCare components end-to-end: gather requirements, design scalable systems, implement production-grade backend code (primarily Python), review C code, operate components in production, and provide technical product ownership and mentorship.

Design, implement, automate, monitor, and operate hybrid cross-data-center and cloud networking. Own production changes end-to-end, troubleshoot incidents (BGP, IPsec, Linux networking, Kubernetes CNI), improve observability and automation, maintain runbooks, and collaborate with SRE, Security, Platform, and delivery teams.

Join CloudLinux as a Kernel Developer focused on creating patches for Linux kernels and improving cybersecurity. Responsibilities include updating kernels, providing support, and assisting with automation.

Lead the evolution of CloudLinux's data platform, focusing on automated DBaaS architecture, data analytics support, and implementing SRE practices.

The SDET Automation Lead will develop a QA strategy, mentor engineers, enhance automation processes, and improve product quality metrics using AI. Responsibilities include overseeing quality metrics, team culture, and reporting systems.

Support and maintain Linux infrastructure: manage user access and DNS, provision and maintain hosts across bare metal, cloud, VMs and containers, configure firewalls and updates, monitor systems and respond to incidents, handle Jira tickets, implement CI/CD automation, and produce clear documentation.

Investigate upstream Linux kernel fixes, backport patches to older RPM/Debian kernels, resolve conflicts, build reproducible kernel packages, validate patches with tests and regression analysis, and improve workflows using Python/Go/Shell and automation tools.

Maintain and modernize the Patchman backend infrastructure, build and test new product features, operate a large fleet of servers, improve CI/CD pipelines, monitor and optimize performance and reliability, debug complex production issues, and collaborate cross-functionally on architecture and technical direction.
