Role & responsibilities

- Manage and maintain Linux servers across production, staging, development and experimental environments.

- Keep infrastructure organized, documented and reproducible, including server inventory, access credentials, DNS, certificates, networking and service ownership.

- Deploy, configure and maintain Docker-based applications, databases, reverse proxies and supporting services.

- Implement monitoring, alerting, logging and uptime checks across all critical systems.

- Establish and maintain reliable backup, restore and disaster-recovery procedures, including regular recovery testing.

- Manage operating-system updates, security patches, SSH access, firewalls and server hardening.

- Automate repetitive administration work using tools such as Ansible, Terraform, shell scripting or equivalent.

- Maintain clear separation between production systems and experimental/development infrastructure.

- Monitor disk usage, memory, CPU, network traffic and infrastructure costs and proactively resolve issues.

- Troubleshoot server, networking, deployment and performance problems.

- Maintain documentation so another administrator can understand and recover the workplace without relying on tribal knowledge.

- Work closely with developers while taking primary responsibility for infrastructure stability, cleanliness and operational discipline.

- Help standardize deployments and gradually eliminate manually configured or undocumented infrastructure.

- Participate in incident response and perform root-cause analysis when systems fail.

- Maintain databases and storage infrastructure,



including PostgreSQL and other data services, without requiring application-development ownership.

Preferred candidate profile

- 36 years of hands-on Linux system administration, DevOps or infrastructure experience.

- Very comfortable administering Linux servers from the command line.

- Strong understanding of networking, DNS, TLS/SSL, SSH, firewalls, HTTP and reverse proxies.

- Practical experience with Docker and containerized production environments.

- Experience with Nginx, Caddy, HAProxy or similar technologies.

- Good understanding of backups, replication, disaster recovery and infrastructure security.

- Experience with monitoring tools such as Prometheus, Grafana, Uptime Kuma, Zabbix or similar.

- Familiarity with infrastructure automation such as Ansible, Terraform or shell scripting.

- Experience managing dedicated servers, VPS providers and cloud infrastructure.

- Comfortable working with Git and CI/CD pipelines.

- PostgreSQL/Linux database administration experience is a strong advantage.

- Kubernetes experience is helpful but not required.

- Strong organizational habits and an instinct for documentation, standardization and automation.

- Someone who notices an undocumented server, expiring certificate or missing backup and wants to fix it before being asked.

- Comfortable supporting a fast-moving engineering environment while being conservative and disciplined with production systems.

- We particularly value candidates who enjoy making infrastructure boring, predictable and reliable rather than constantly introducing new technologies.
