As an automation technician, your responsibilities include checking these systems and diagnosing and isolating problems by performing tests to then repair or replace parts. Other duties include installing upgrades and modifications as needed. You are expected to stay updated on the most cutting-edge technological developments in your industry and provide insight into improved processes where possible.
