I'm asking on someone's behalf.

He's a very experienced (20+ years) analogue electronics engineer who's currently doing some bits and bobs to stay afloat, however, it isn't really enough to pay the family bills.

His areas of expertise are audio and sensitive measurement (think photons) and is definitely a mad genius type.

Is his a dying breed/skill or are there well paid jobs out there which just aren't being advertised?

Thanks.
