May be I stretched the meaning of numerical software a little
to far. At best it is seminumerical, but I did not have an example of well documented code at hand to make my point with true numerical software.


I think the difficulty in numerical/scientific software is not in the coding part itself, it is in having the knowledge to understand the problem itself that you are solving and coding a solution for.

These are a couple of positions at JPL, they require coding in what I would consider scientific software, numerical area.

-------- "Required Skills: Ph. D. in physics or space physics with 1-6 years of experience, Masters
with 3-8 years of experience or Bachelor's with 5-10 years of experience or equivalent.
...
of computer equipment. Demonstrated experience in FORTRAN programming. "

---------

"Required Skills: Ph.D in Analytical Chemistry with 1+ years of experience, or
MA/MS degree with 3+ years experience, ......Experience using MATLAB, PLS tool box, GRAMS"

I do not think I ever seen a job posting asking for a PhD as a qualification to write a web page or an SQL application or even a device driver.

I could not agree more. That is why I underlined the meaning of a good
education.

For writing a device driver you maybe need more engineering
capabilities?
