These are not separate concerns. Morality is a necessary part of competence.

[citation needed]

In any case, here the intended meaning was clearly "technical ability", which doesn't require morality

If there's one belief I think needs to be more widespread in technical circles, it's this. Good engineers recognize the impact of their engineering, and engineer for social good. We don't remember programmers because of how good their programming was, we remember them because of how good the programs they made were.

it's the engineer part that suggests the moral uprightness. without that, it's more "developer"

"good" as in having the qualities required for a particular role, as per Google.
