A weekend engineer works part-time (usually on weekends and evening hours) to service equipment for various companies that they use in their operations. In addition to weekend shifts, some positions also require you to have on-call hours available on a rotating schedule with other engineers. Your responsibilities vary depending on the job and the company for which you work. For an IT company, you may service computer equipment, internet lines, and other technical equipment. In a factory position, you may work on production line equipment, such as conducting routine inspections and maintenance on equipment, ordering parts for replacement, and repairing broken or worn-down equipment.
