I have also done safety-critical H/W and S/W design mostly under IEC 61508.
At the engineering level, software quality is only obtained by documenting it to death- every requirement, subroutine function, test cases- all documented and signed off. With everything ultra-defined, then the S/W can be coded by clowns and still be decent. IEC 61508 has entire sections devoted only to a corporation's quality system, project management, and even employee qualifications to do safety-critical work in the first place.
Of course this takes forever and companies skip over things, cheat the process- extra easy to do when outsourcing.

I see most credentials are fake, especially when you ask a few simple questions.
