Even when I graduated in the 80's, electronics was already in decline as a career choice for the UK. However, I would say other fields of engineering have remained strong, such as mechanical, civil, chemical, and probably electrical power systems. For mechanical and civil, there have been megaprojects like Crossrail and HS2, and multitudes of other projects that are always going on. For electrical, there is of course the huge interest in sustainability, wind farms, power conversion and so on. In the UK in particular, with the move to offshore windfarms instead of onshore central generation, the electrical grid is the wrong shape and needs to be reengineered over the coming decades. Not to mention that the aforementioned megaprojects like Crossrail had/have an enormous electrical content for power, communications and signalling.
My suggestion to find a good career in engineering, would be to seek out big projects and industrial enterprises, and avoid consumer product manufacturing.
The same considerations would apply overseas as much as in the UK.
