• - 10+ years of experience in a System Operations or related role, with a strong background in high-demand industries such as broadcast, media, or digital video.
• - Advanced expertise in Linux administration, with hands, *.
• - Deep knowledge of configuration management tools like Rudder, Chef, or Puppet, with experience enforcing configuration standards and maintaining consistency across environments.
• - Proficiency in managing and fine-tuning monitoring tools (e.g., Zabbix, Prometheus) to track performance metrics, create alerting mechanisms, and optimize system observability.
• - Extensive experience conducting regular maintenance, applying patches, troubleshooting performance issues, and tuning systems to maximize efficiency and uptime.
• - Strong skills in mentoring junior engineers, sharing best practices, and documenting processes and procedures to build a robust knowledge base for the team.
• - Familiarity with open-source storage technologies (e.g., Ceph, ZFS) and network routing tools like FRR and Quagga to manage data flow and ensure high system reliability.
• - Proven experience in capacity planning and scaling strategies to support both current and anticipated demand across infrastructures.
• - Advanced scripting skills (e.g., Bash, Python) to automate system tasks and enhance configuration management workflows.

Nice to have:

• - Experience with or exposure to CDN infrastructures.
• - Exposure to edge computing and real-time system demands.
