First, Stephen you are looking for Software System Safety Engineers for
the design, verification and validation of hardware and software systems
used in monitor and/or control of hazardous functions.

These are a rare breed in the fully developed sense that Mr. Keller is
alluding to (SIL is from IEC 1508 and other Euro standards for
Programmable Electronic Systems (PES)). There are several who do dally in
the software, and some who dally in the hardware. But if you vary the
hardware "chips" or the software "language" then you'll find that
individual back at the same starting point as another. Expertise is quite
narrow (due to the learned technology) in most.

For example, Mr. Keller states that he prefers Ada but does not caveat
under what conditions. I am presently on still another Ada project in
which there are single point failures caused by how that language is
used...

I personally have trouble with the myriad of PLAs, EPLDs, FPGAs and other
"circuits" while I seem to have conquered safety in VHDL as a language.

As to where you will find them...there are a few to refer to and others
growing up in the business, but you will always find only a few dozen, and
then you need a re-trainable one so that they can change hardawre and/or
software (see above) at least once a year...

cheers,
and yes I did get you email to arrange those standards you've asked for,
but I haven't had time to get it finished. Saturday I had to put a horse
down for fatal colic and the day was shot.
