Build the internal platform that powers our engineering teams, delivering mission-critical software to 4,000+ cloud hosting providers worldwide.
CloudLinux powers 4,000+ hosting providers managing millions of websites globally. Our infrastructure team is at a critical inflection point – moving from 8+ years of technical debt to building a modern platform. This isn't a typical SRE role; it's a chance to architect the future of infrastructure that cannot fail.
Where we are : Legacy systems, reactive operations, bus factor = 1. OpenNebula bottlenecks blocking releases. 70% time on firefighting.
Where we're going : Self-service platform, Infrastructure as Code, proactive engineering. You'll be one of 2-3 senior engineers leading this transformation alongside a new Infrastructure Director with full B-level support.
What You'll Actually Do
Stabilize & Assess :
- Deep dive into OpenNebula issues with the existing team
- Map critical dependencies and single points of failure
- Implement quick wins (automated VM cleanup, monitoring gaps)
- Begin documenting undocumented systems
Build Foundation :
Leading the design and development of an internal development platform (IDP)Implement GitOps for critical workflowsEstablish SLIs / SLOs for core servicesCreate runbooks for top incidentsTransform Platform :
Architect self-service Internal Developer PlatformDrive Infrastructure as Code to 60%+ coverageEliminate single points of failureDrive development and implementation of complex architectural decisionsTechnical Stack You'll Transform
Current :
Virtualization : OpenNebula (main bottleneck), oVirt / OpenStack / CloudStack, KVMStorage : Ceph (recently stabilized), Cephadm, RookNetwork : JuniperBare metal (3 Datacenters) + AWS + Google Cloud + AzureAutomation : ~5% Terraform coverage, manual operations dominantCI / CD : Gitlab, Jenkins, Gerrit, GithubYour Tools for Transformation :
Kubernetes & KubeVirt and / or all necessaryTerraform / Terragrunt + AnsibleGitOps (ArgoCD / Flux)Python / Go for custom toolingModern observability stackRequirements
To thrive in this role, we are looking for someone who has :
Migrated legacy systems to modern platforms at scaleStrong Kubernetes production experience (multi-tenant, federation)Infrastructure as Code expertise (Terraform / Ansible in production)Linux at scale (RHEL / CentOS / AlmaLinux, 1000+ servers)Network fundamentals, underlay, overlay, (EVPN, BGP, VXLAN, DNS, network architecture & segmentation, native pod networking at scale)Proven ability to work independently with minimal documentationExperience building self-service platformsEnglish B2+ and excellent documentation skillsCritical Mindset :
Comfortable with ambiguity and technical debtPragmatic : know when to fix vs. replace vs. work aroundCan balance firefighting with strategic improvementsStrong opinions, loosely heldTeaching mentality – you'll help upskill the teamWhat Makes You Successful Here :
You'll have significant technical decision-making power and direct impactNew Infrastructure Director + B-level backing for transformationApproved investment in people and technologyFull authority to simplify and modernizeProtected time for strategic work, not just operationsThe Opportunity
This isn't about maintaining the status quo. You'll :
Define infrastructure strategy affecting 4,000+ companiesBuild an internal development platformLead technical transformation with real budget and supportBecome the principal architect of a modern platformWork directly with the Infrastructure DirectorShape how critical infrastructure software gets delivered globallyBenefits
