Senior Linux / Proxmox / PBS DevOps — Infrastructure Audit, Backup and Recovery

Work Format: Remote, candidate location is not important Employment: Part-time / Project-based, hourly pay Salary Range: from 15 to 30 $/hour (net) Hiring Specifics: Russian-speaking engineer required. For the first stage, we work via screen sharing — the specialist explains actions, and we perform or confirm them on our side. Direct access is discussed separately and only if necessary.

Job Description:

We are looking for an experienced DevOps / infrastructure engineer to work with a production infrastructure on Proxmox VE (several services, including web and telephony). We need to conduct a thorough audit, check backup processes, help with the safe recovery/rebuilding of a problematic LXC container, and prepare a practical plan to increase reliability.

We need an engineer who first analyzes the situation, explains the risks, and records the actions, and then makes changes — not just "install packages".

Tasks:

• Audit Proxmox VE / LXC / storage infrastructure;
• Check Proxmox Backup Server and current backup processes;
• Safe restore test in an isolated environment;
• Recovery / rebuilding of a problematic LXC container;
• Risk assessment of the current infrastructure;
• Recommendations for deletion-resistant / immutable / offsite backup;
• Basic security hardening without chaotic changes on production;
• Short written report: what was checked, what are the risks, what to do next.

Required Experience:

• Confident Linux administration;
• Practical experience with Proxmox VE and Proxmox Backup Server;
• Work with LXC containers, troubleshooting and recovery of containers / VMs;
• Understanding of storage, filesystem, raw/qcow2 images;
• Experience with backup / restore tests;
• Careful work with production and the ability to explain risky actions before executing them.

Will be a plus: Asterisk / VoIP, Plesk, immutable backup, S3 Object Lock, ZFS snapshots, offsite backup, disaster recovery planning, security-sensitive cases.

We will start with a short paid assessment (initial audit + backup/restore check + risk assessment and action plan). If the approach and quality are suitable, we will continue. In your application, please indicate your rate and when you are ready to start.
