Customer service technicians assist customers with resolving technical issues with their service or equipment. As a customer service technician, your job duties include responding to customer technical service requests, troubleshooting technical issues, and reporting the resolution of these issues back to management. You are often the primary liaison with the customer on behalf of the company, so a friendly and professional attitude is required. To pursue a career as a customer service technician, you need a high school diploma or equivalent and industry-specific experience, though many employers provide on-the-job training.
