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.
