• Work closely with developers to optimize deployment workflows and runtime environments

• Use AI tooling effectively (Claude, ChatGPT, internal MCP tools) to improve productivity and automation

Required Skills and Experience

• Solid Linux administration experience, preferably Debian-based systems

• Hands-on experience with Docker in production environments

• Working knowledge of Kubernetes fundamentals and deployment mechanisms

• Good understanding of networking fundamentals (TCP/IP, DNS, routing)
