Top Tech Jobs & Startup Jobs

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.

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.

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.

Join as an early-career engineer working on CloudLinux OS, KernelCare/TuxCare, or security tooling. You'll solve real product tasks with mentorship, complete a practical challenge using AI tools, and grow technical and systems skills while contributing to production systems.

Lead and transform QA into an AI-driven quality engineering function: set QA strategy and metrics, expand multi-distro test coverage, own test infrastructure and CI/CD, mentor SDETs into product-quality engineers, drive automation and AI tooling adoption, and collaborate with developers to prioritize quality work.

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.

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.

The Staff Engineer will lead the architectural design and technical direction for new initiatives, collaborate with teams, and promote engineering excellence. Responsibilities include gathering requirements, guiding engineering teams, and ensuring robust solutions in production environments.

The Senior IaaS/Kubernetes Platform Engineer will design, implement, and operate a multi-tenant Kubernetes platform and infrastructure, focusing on Kubernetes, storage, and networking engineering, reliability, automation, and proactive improvements.
