Job summary

Adapty is seeking an experienced infrastructure lead to take ownership of Proxmox and Ceph end-to-end, driving capacity planning, upgrades, and performance across OVH, Hetzner, and bare metal.

You will manage deployments in AWS/GCP, lead cost optimizations, and split development workloads into isolated clusters, all while keeping everything as code and ensuring reliability across the platform.

Qualifications

• 10+ years working with infrastructure and physical hardware, not only managed cloud.
• 5+ years running Kubernetes and cloud platforms in production.
• Hands-on with bare metal and providers like OVH and Hetzner, plus AWS and/or GCP.
• Strong with Terraform, Ansible, ArgoCD and GitLab CI — you describe infrastructure in code by default.
• Real FinOps experience: you can name what infrastructure cost before and after you touched it.
• You take problems all the way to the root cause and to the fix, including outside your formal scope.
• You say things directly — risks and bad news arrive early, not after the incident.

Responsibilities

• Own our Proxmox and Ceph platform end to end — capacity, upgrades, performance and incident response
• Run infrastructure across OVH, Hetzner and bare metal, alongside workloads in AWS and GCP
• Drive resource rightsizing: find where we overpay, size it correctly, and prove the saving in the bills
• Lead the separation of development workloads into a dedicated cluster, without downtime for production
• Keep everything as code — Terraform, Ansible, ArgoCD and GitLab CI, with no manual changes in production
• Own reliability: on-call, incident response, root cause analysis and the runbooks that follow
• Support the data layer our product runs on — PostgreSQL, ClickHouse, Aerospike
