Job description

We're looking for an experienced Linux engineer with 10+ years of hands‑on experience to own and run infrastructure. You'll be the go‑to expert for Linux, Proxmox and core network services, with a strong focus on automation, consistency and reliability.

Location: Remote Experience: 10+ years in Linux systems engineering

What You'll Do

• Own Proxmox environments end to end, from building and running clusters to managing VMs, with changes automated through Ansible.

• Run and maintain Postfix mail servers.

• Build and maintain WireGuard VPNs across offices, servers and environments.

• Operate and maintain Unbound for DNS resolution.

• Design and maintain high‑availability setups using CARP.

• Use Ansible as the standard way to provision, configure and maintain servers.

• Monitor, tune and troubleshoot Linux systems, and turn recurring fixes into automation.

• Take end-to-end ownership of the services you run, from design through to production support.

• Participate in and respond to production incidents and drive them to resolution.

• Proactively flag risks, misconfigurations or technical debt before they become incidents.

What We're Looking For

• Expert‑level Linux administration.

• Proven production experience with Proxmox.

• Strong hands‑on experience with Postfix, WireGuard and Unbound.

• Experience building high‑availability setups with CARP.

• Strong Ansible skills and a habit of automating anything done twice.

• Strong troubleshooting skills and attention to detail.

Behavioral Attributes We Value

• Ownership mindset: You treat the systems you run as your responsibility.

• Accountability: You're comfortable saying "this was my change" and equally comfortable driving the fix and the retrospective afterward.

• Proactive communication: You escalation early, keep relevant people informed during outages, and don't let problems sit silently.

• Continuous improvement: You use incidents and mistakes as input for better monitoring, automation or process.

Nice to Have

• Experience with AWS, Terraform and GitLab CI.

• Experience with Docker.

• Familiarity with Agile methodologies.

• Experience with observability tools (e.g., Datadog, Grafana, Prometheus) for incident detection and debugging.
