That is surprising in financial software. You could add the famous
"shave off all the rounded numbers into my Swiss bank account"
function in your code, and no one would audit it?
We can't even do that in "answer the phone line" code in telco --
hearing that there's ever only ONE engineer in charge of a function in
financial code, doesn't give me warm fuzzies.
(Yeah, I know they'd catch the above example, but you get the idea.)

I guess it doesn't manage risk all that well -- or your customers all
didn't lose 30% last year like everyone else? Hahahaha...
Well, you did say you were "feeding code to the financial crisis", and
everything I've heard is that the mortgage stuff was quite heavily
affected by "computer models". Not that I don't hold the dolts who
BELIEVED the models responsible, mind you... but it's interesting stuff.

That right there says something. The best rarely think they are. :-)

If they're reprioritizing on a "management whim", the managers aren't
very good and don't have very good goal-setting skills in the first
place. So I wouldn't put too much stock in that "best programmers"
thing, since they're not very good managers to begin with.

One that writes award-winning software, and one that doesn't? Heh heh.
And meanwhile the bank using the software should have just turned the
idiot with the nose-ring and his girlfriend wearing the "I'm with
Stupid" T-shirt down for the loan... hah.
Isn't your job as you described it -- as an individual -- already a
"small team" within that bigger whole that gets those big projects
done? You do things you say the other's can't, you have your own
deadlines and goals... things change, you adapt... sounds "Agile" to me!
This is why (and I don't like this model, but it's still commonly
done) many companies break up "Product Engineering", and "Continuation
Engineering" into different departments that don't co-mingle.
How about pushing for code that needs LESS maintenance from the
start? Write once, use. :-)
(Everyone says it's impossible, but we've all seen small projects
where it somehow worked out and the "thing" hasn't been touched for
years, and still works. I'm not a programmer by trade, but it seems
to me like Agile is all about just scaling that "small win" type
situation up into the building blocks for a bigger project, isn't it?)
It *is* possible to write almost perfect code, after all...
