Zusammenfassung

Papers AG invites an experienced DevOps/SRE to join our infrastructure team in Switzerland. You will manage a self-hosted Linux-based stack across dedicated hardware, implement CI/CD pipelines, and optimize Docker/Docker Compose deployments while automating provisioning with Ansible.

You will own security posture, incident response, and monitoring with Telegraf, InfluxDB, Grafana, Graylog, and PagerDuty, collaborating closely with engineering across the stack.

Qualifikationen

• 3+ years of hands-on experience in DevOps, SRE, or infrastructure roles.
• Proficient with Linux/Ubuntu system administration on self-managed servers.
• Comfortable with Docker / Docker Compose and CI/CD workflows (GitLab CI).
• Experience with infrastructure-as-code (Ansible especially).
• Confident with Nginx, TLS, shell scripting, and practical networking (reverse proxies, firewalls, VPN/overlay networks).
• Comfortable owning a metrics/alerting stack and responding to incidents.
• Solid grasp of security fundamentals: identity & access management (MFA/SSO, least privilege), host hardening, secrets handling, and patch management.
• Strong written and verbal communication skills in English.
• Self-driven, self-organized, pragmatic, and comfortable working independently.

Aufgaben

• Manage and improve our self-hosted, Linux-based infrastructure (Ubuntu) running on dedicated servers.
• Keep servers patched and up to date (OS/security updates, reboots) and maintain the various applications we self-host.
• Design and maintain CI/CD pipelines (GitLab CI): build images, push to the GitLab Container Registry.
• Set up and optimize Docker and Docker Compose deployments.
• Automate infrastructure and host provisioning with Ansible.
• Define and enforce backup strategies and disaster-recovery processes.
• Run our observability stack — Telegraf + InfluxDB + Grafana for metrics and alerting; Graylog for log aggregation.
• Administer Microsoft 365 / Entra ID (Azure AD) — identity & access management, MFA, Conditional Access, SSO, and email/collaboration security.
• Own and continuously improve our security posture: SSH/host hardening, firewalls, secrets management, least-privilege access, periodic access reviews, and incident response.
• Participate in on-call rotations to support critical services (incl. Acurast blockchain/bridge infrastructure).
• Collaborate with backend engineers to streamline integration and delivery.
• Continuously identify and automate repetitive tasks to reduce manual intervention.
