Is this sentence grammatically correct?

"To secure a full-time, permanent position in which I can contribute my experience and skills performing manual labor, equipment operation, and roadway/highway reconstruction as a functioning member of a maintenance crew that helps Oregon communities."

works better for me, as "My objective" is not required after the colon in the title preceding it. Also position is used as a synonym for role, not as a place, so "in which" is preferable to "where", in my opinion.

Also I do wonder if stating that helping Oregon communities is superfluous.
