technician

A technician is a skilled worker who applies practical knowledge and hands-on methods to install, maintain, troubleshoot, or repair equipment, systems, or processes in various industries. Technicians often work under supervision and rely on standardized procedures, specifications, and safety guidelines.

Common fields include science and engineering (laboratory technicians, field service technicians), information technology (IT technicians, help desk), manufacturing and electronics (electronic technicians, electrical technicians), healthcare (medical laboratory technicians, radiology technicians), automotive and aerospace (maintenance technicians), and construction trades (HVAC technicians).

Most technicians complete a postsecondary certificate or an associate degree from a technical college or vocational school. Apprenticeships, on-the-job training, and industry certifications (such as CompTIA A+, IPC, or manufacturer-specific credentials) are common.

Duties may include installing equipment, setting up and calibrating instruments, diagnosing problems, performing routine maintenance, recording data, ensuring compliance with safety and quality standards, and communicating findings to supervisors.

Work environments vary from labs and clinics to factories and field sites. Career progression often follows a path from technician to senior or lead technician, supervisor, or manager; with additional education, a technician may move into technologist or engineering roles.
