Darrel Ince (in the Guardian article) gave us an insight into the problem when he wrote of scientific software being: "... produced by software engineers who have to undergo a regime of thorough testing, quality assurance and a change control discipline known as configuration management." Two things are worth noting in that quotation: 1. My reading in the field leads me to believe that "thorough testing, quality assurance and a change control discipline" are pretty thin on the ground in COTS software houses; 2. There aren't a lot of Software Engineers around (if you emphasise 'Engineer'). Bear in mind that Engineering is an attitude, not a qualification. I believe that these are two of the foci Bob is looking for. Good luck, Bob.
