Jobs at Cloudlinux

Operate and support Linux infrastructure across bare metal, private cloud, and public cloud environments. Troubleshoot systems, networks, DNS, and services; manage access, provisioning, firewall and operating-system changes; monitor alerts and resolve incidents; handle Jira requests; deploy approved services; and improve recurring procedures through documentation and small automation changes.

Entry-level graduate engineers will develop and test software features, investigate production issues, improve automation, understand unfamiliar code, and contribute to code reviews and technical discussions. The role focuses on Linux infrastructure, open-source software, web-hosting security products, and thoughtful use of AI tools. Candidates will learn alongside experienced engineers in a fully remote environment and complete a practical engineering challenge during the selection process.

Drive enterprise sales growth across Japan and East Asia by generating pipeline, managing complex sales cycles, expanding existing accounts, developing channel partnerships, and negotiating localized software subscriptions and licensing agreements. The role requires autonomous territory development, executive-level engagement, and fluency in Japanese and English, with familiarity with Linux, cloud, hosting, or cybersecurity technologies.

Lead CloudLinux’s remote innovation team in taking product concepts from discovery to customer-tested MVPs. Own the idea pipeline, prioritization, success criteria, customer research, prototypes, technical direction, go/no-go decisions, and product handoffs. Build and review code, guide AI-assisted engineering, ensure production-ready releases, and lead hiring, coaching, and performance management for a distributed engineering team.

Build and productionize machine learning systems for web-malware detection using classifiers, transformer models, LLM-assisted triage, and generated signatures. Work with large malware datasets, develop leakage-free evaluations, optimize inference for CPU and memory constraints, and validate improvements against false-positive and false-negative regression sets. Collaborate with malware analysts and infrastructure engineers to deploy detection and cleanup models at fleet scale.

Staff Engineer leading cross-product architecture and technical direction for Imunify360, a Linux server security platform. Responsibilities include solving cross-squad scalability, detection, performance, upgrade, release, and security challenges; driving ADRs, engineering standards, observability, incident response, and secure development; mentoring engineers; and contributing 30–50% production code. Requires deep Python and Go or Rust experience, Linux internals expertise, distributed systems experience, customer-hosted software ownership, and strong security engineering judgment.

Own automation and infrastructure outcomes across cloud costs, inventory, network policies, and capacity workflows. Build reliable Python systems and cloud API integrations, transform and reconcile billing and inventory data, deliver infrastructure changes through IaC and CI, and maintain monitoring, documentation, testing, and safe recovery processes. Collaborate across engineering, Finance, and Security while diagnosing issues across Linux, networking, APIs, data, and cloud environments.

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.

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