Senior Linux Administrator / Infrastructure Administrator

Gaijin Games

Remote · ArmeniaSalary not disclosedfull-timeVerified recentlyhh.ru

Gaijin Entertainment is looking for a Senior Linux Administrator to join the infrastructure team. We make AAA online games (War Thunder, Enlisted and others) and we run the internal infrastructure that development, testing, CI/CD, the teams' services and part of the production/support systems all live on.

Responsibilities

We make AAA online games (War Thunder, Enlisted and others) and we run the internal infrastructure that development, testing, CI/CD, the teams' services and part of the production/support systems all live on. This is not a build engineer position: we have separate people who own build logic. The focus here is systems administration, server reliability, automation, IaC and the infrastructure around development.
This is a senior role where you can visibly shape how the infrastructure of a large game studio is put together. The foundation is already there and it is a strong one: servers, virtualisation, the build/test fleet, storage, networks, monitoring, backups, IaC and internal tooling. That said, we do not consider the infrastructure "finished": it can and should be made simpler, more reliable, clearer, more convenient and more measurable.
What you will be doing:
Administering the Linux infrastructure: servers, services, access, updates, diagnostics, network configuration, system problems and incidents.
Growing infrastructure as code: describing infrastructure in code, maintaining the role and host configurations, making changes through Git/Gerrit, code review and CI.
Taking part in the large planned migration of the whole infrastructure from SaltStack to Ansible. This is not "rewriting YAML for the sake of YAML" — it is a chance to design a modern IaC platform together with the team: inventory, roles, secrets, CI checks, rollout processes and the rules for running it all.
Looking after a large fleet of build/test nodes: Windows, Linux and macOS machines, powerful workstation/server-class configurations, GPU nodes and specialised test environments. The build team owns build logic; the infrastructure team owns keeping that fleet reproducibly provisioned, available, monitored and managed through IaC.
Looking after virtualisation and the server platforms: Proxmox, Linux VMs, the network and storage dependencies, templates, provisioning and the operational procedures.
Looking after the infrastructure services: Docker, nginx, DNS, VPN, monitoring, logging, backup/restore and the internal services the development teams use.
Helping improve the internal tooling: we have a lot of engineering code in Gerrit — IaC, monitoring, backup tooling, access management, inventory, Jenkins integrations, automation scripts and shared libraries.
