• Strong cable management and structured cabling skills (fiber and copper)
• Ability to read and follow technical documentation, diagrams, and procedures
• Strong problem‑solving skills and attention to detail
• Ability to multitask and adapt in a fast‑paced environment
• Strong teamwork and collaboration skills, with the ability to work independently when needed
