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.

- Robust 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 escalate 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.
