The two heads who lead the R&D and engine development are not software engineers. But they would certainly require software engineers to help them carry out the deception. I highly doubt that only 2 people are involved.
perhaps 2 people who were intentionally intending to mislead. the software engineers could have been told the software was for factory testing only and it would have been their job to produce it. The actual program itself was not illegal just the fact that it was used to mislead official testing.
This ain't no 'independent contractors on the Death Star' issue here.
