Use these synonyms if you do not like engineer. synonyms: originator, deviser, designer, architect, inventor, developer, creator; mastermind "the prime engineer of the approach"

If you do not think that engineers can be creative then we disagree. And if you think that every writer, actor, director is creative, then we also disagree.

Replace "engineers" with "the people who actually do the real work" and your complaint goes away.
