After your first sentence I thought you'd continue like this:

For a hacker, making something fast and cool is the most important aspect, whereas for engineers making careful tradeoffs between effort and customer impact are the main focus.

I think you could swap 'hacker' and 'engineer' in your sentence and it would still make sense.

I'm not saying, "engineer bad, hacker good", just that we tend to value "good" code, architecture, performance, etc highly and sometimes that is to our detriment.
