Job Summary

GKN is actively engaged in a series of major, multi £M development programmes with the long term aim of enabling zero emission flight on a series of new aircraft programmes. We want to enable the complete electrification of Aircraft powered by Liquid Hydrogen, Fuel cells and Cryogenically cooled networks and motors. As such we’ve already built up a significant capability with an international team of over 70 specialist Engineers working on Liquid Hydrogen based propulsion systems, including storage (tanks), Fuel management, Fuel cells, Electrical networks, Motors and Inverters, with Cryogenics being an enabling technology. This ground breaking technology is maturing rapidly and we’re searching for specialist Engineers and Scientists who want to work with us in this rapidly changing, dynamic, multifunctional environment to help us push further and faster as we win more programmes and the market accelerates.

We are looking for a Fuel Cell & Thermal Systems Technical Authority who can operate across multiple projects within Horizon 3.
