Job description

At iST Power, we specialise in the development of transformers that play a vital role in supporting critical infrastructure. Our expertise extends to solutions for renewable energy, distribution network operator equipment, and defence projects commissioned by the Ministry of Defence. Through our custom-designed transformers, reactors, and power magnetics, we contribute to the reliable operation and advancement of essential systems worldwide.

We aim to be a first-choice supplier by operating as a first-rate business that delivers a first-class product. Our commitment to innovation, sustainability, and continual improvement is backed by internationally recognised standards.

We are a medium sized, privately owned, company and our employees are heavily involved from day one! We drive for innovation and are proud of our mission to have a "First Class Product", and this is being met by our continued investment in our stand-out product range, which is exceeding our customers' expectations and, in some instances, leading the world.
