[Hiring] Infrastructure Engineer @DigitalTolk

Role 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.

Qualifications

• 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 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.
