• Experience with storage technologies (block and object), including usage of Kubernetes-native, AWS S3-compatible object storage solutions
• Strong networking fundamentals with hands-on experience in TCP/IP, routing protocols, network security, and data transfer optimization for distributed storage environments
• Experience with observability tools (Prometheus, Grafana, ELK stack) for large-scale monitoring and analysis
• Some automation experience using Python/Go scripting or Chef configuration management
• Excellent attention to detail and ability to make sound, timely technical decisions
• A focus on security when managing systems and developing/reviewing code
• Passion for documentation and commitment to improving knowledge transfer across teams
• Proficiency with project and program management tools (e.g.: Jira, Gitlab)
