• Scripting and Automation: Proficiency in Bash and Python, or willingness to learn, plus familiarity with Ansible.
• Containerization & Virtualization: Knowledge of Podman, Kubernetes, Helm, and/or OpenStack; experience with KVM/QEMU is advantageous.
• Storage Systems: Experience with Ceph and Rook is highly valued.
• Database Expertise: Understanding of relational databases (MySQL, MariaDB) and experience with etcd.
• Monitoring and Logging: Familiarity with tools like ELK (Elasticsearch, Logstash, Kibana), Prometheus, and Grafana.
• Advanced written and spoken English.

It would be nice if you also had
