The Engineering Council is a good place to start when looking for engineering info. It gives you info about the courses and qualifications.
You will see a list of chartered engineering institutions. Look at the major ones which correspond to university courses. So look at civil, structural, mechanical, electronic, electrical, environmental etc. See what interests him at each one. Structural is closest to architecture but is usually taught with civil engineering.
Universities worth looking at for info would include Sheffield, Bristol, Southampton, Loughborough and Manchester. There are others of course but these unis are a good place to start.
As for jobs: some engineering grads go into finance work. Others are well placed to get a job. Be proactive and employment is available for the majority. Architecture is less stable - I agree with pp above.
When looking at engineering degrees, try and go for MEng. If a young person intends to be a chartered engineer, this degree is the quickest route. BEng is slower and requires further study to elevate the degree. Chartered Engineers usually commend a premium in consultancies.
