GATE Instrumentation Jobs

A favorable GATE Instrumentation rank for PSU is the key to this achievement. The required tasks in GATE Instrumentation are very domain specific; An Instrumentation Engineer typically works for automated industries with the objective of improving the productivity, optimization, safety and reliability. With the latest advent of AI in the picture, robotics is an interesting and intriguing field that requires multidisciplinary skills including Instrumentation and Control as an important component. The interdisciplinary nature of the stream opens opportunities for Instrumentation Engineers in various sectors like Research & Development units, heavy industries as thermal power stations, steel plants, refineries, cement and fertilizer plants. Last few decades have expanded it's sphere into varied other exciting fields like Biomedical, Nuclear, Mining and Metallurgy and Aerospace applications too. Last few decades have expanded options after GATE Instrumentation into varied other exciting fields like Biomedical, Nuclear, Mining and Metallurgy and Aerospace applications too. Some of the key recruiters that hire Instrumentation Engineers across India are Larsen & Toubro, GE, Suzlon, ESSAR, Robert Bosch, Reliance industries Ltd, Tata Consultancy Engineers, Tata Power, Siemens Ltd, Chemtrols and Emerson, Invensys Technologies etc.
